    By Rachel from NC on November 6, 2013
    I am looking to install propane gas logs into a working fireplace. Should I buy ventless gas logs or vent logs? I am going to keep the flue closed because I need to heat the home.
    By Collin C. - NFI Master Hearth Professional on November 6, 2013

    Your application will call for ventless logs to be used. This is the only type of set that can be safely used with the flue damper shut. They are also the superior choice for supplemental heating purposes, as vented logs are primarily for appearance and offer little supplemental heat.

    By Gary Shilling from Canada on November 18, 2016
    II am looking to add a ventless fireplaces to my new home, but I'm wondering if you design anything that doesn't look like logs or charcoal. What I'm thinking of is an arrangement of rocks.

    By Andy Tate from Cincinnati, Ohio on January 1, 2013
    Can ventless gas logs be installed in a standard fireplace? Would venting still be required?
    By Tyler M. - Fireplace Specialist on January 2, 2013

    Yes, ventless gas logs can indeed be installed in a masonry/brick fireplace or a manufactured wood-burning fireplace that has been tested and listed to accept gas logs. No venting would be required. In either case, the damper for the existing fireplace would be closed.

    By Sheryl from Charlottesville, VA on March 2, 2014
    Our ventless gas logs are causing our fire alarms to go off. What do you think is causing this, and what should we do to correct it? We appreciate your input. Thanks.
    By Tyler M. - NFI Certified Specialist on March 3, 2014

    Whether you have smoke alarms or carbon monoxide alarms going off, we recommend discontinuing the use of the ventless logs set until it can be serviced by a professional. The issue is likely caused by incomplete combustion, which may be a result of improper log placement or gas pressure that is out of the required range. Please call a local reputable plumber to have the unit serviced.

    By Ed from FL on July 16, 2017
    I have a wood burning prefab fireplace in my home and want to switch to gas fire logs. I have been told I should use ventless logs, but continue to use my flue. What is your advice?
    By Kelsey C. on July 17, 2017

    If you were to install ventless logs, there would be no reason to keep your flue open. These are, in fact, designed to be used with the damper closed. Some people might leave them cracked open for air circulation in basements or newer buildings with small square footage, but you will lose heat this way.

    By Carmen from Saint John, IN on November 29, 2013
    I am trying to determine what ventless gas logs will work with our fireplace for model # B36LM. Can you please advise?
    By Collin C. - NFI Master Hearth Professional on November 29, 2013

    Because of the fairly steep taper that the interior of the B36 has, a set of logs such as the Real Fyre 20" Golden Oak Designer Ventless Natural Gas Logs Set with Safety Pilot Kit should be used. A 24 inch set would be too large. We do offer these sets with remote pilot assemblies and in LP fuel, if needed.

    By Robert from Pampa, TX on November 19, 2013
    My fireplace is 30" wide in the front and 24" in the back, but only 13" deep. I think at one time this was a wood burning fireplace just because the house was built in 1926. However, I'm not sure of this until I can borrow my friends little remote camera to poke up the vent. The vent, or opening, is only about 1.25" x 6". I don't know if this is even big enough to be considered vented or not. That is my question. Can I use a vented unit or do I need to get a ventless? I would like to be able to use a vented unit because of the cost and I want to be able to have a more realistic look plus generate heat! Can you give me some advice on this?
    By Collin C. - NFI Master Hearth Professional on November 19, 2013

    Based on the dimensions of your fireplace and the flue opening, the fireplace was likely originally intended for coal burning. Because of the small size of the flue, a vented gas appliance should not be used, as it will release more gas byproducts than the small flue will be able to keep up with. If you are able to verify that the flue is in good condition and not blocked, a vent free set could be used. I recommend inspecting the chimney before proceeding further.

    By Tammie from Delray Beach, Florida on November 29, 2013
    I want to install two ventless propane gas fireplaces in the house I am building in Palm Beach County Florida. Are there any restrictions?
    By Collin C. - NFI Master Hearth Professional on November 29, 2013

    Unvented appliances are legal in the state of Florida at this time, however each local jurisdiction has final authority on the matter. It is recommended to contact your local code office to verify that vent free appliances are legal in your town.

    By Charles from Ridgecrest, CA on November 18, 2015
    Are vent less gas logs allowed in California?
    By Brennan W. on November 18, 2015

    Vent free appliances are not approved for use in California.

    By Ron from Tulsa, OK on November 13, 2013
    I have a vent less gas log with remote that I bought at a local store. I don't like the noise from the pilot and the remote start eats batteries. I would like to buy something to fix it. A wall switch and an electric pilot would be great! What do you think?
    By Collin C. - NFI Master Hearth Professional on November 13, 2013

    While it may be possible to use a wall switch in place of the remote control, I will not be able to offer a solution to the pilot assembly. Vent free burners are constructed with the valve as an integral part of the assembly, due to safety reasons. As such, the valve cannot be separated or changed.

    By Joan from NJ on November 9, 2015
    Our old gas logs for our fireplace are 22 inches long. What size of ventless gas logs do we need to order to replace them?
    By Will M. on November 10, 2015

    Please enter your hearth dimensions into our gas log calculator to view the options that will be available for your fireplace.

    By Nei from Flourtown, PA on October 22, 2016
    I am looking for replacement logs for a Monessen Deb Ember Blaze 24" natural gas log fireplace.

    By eFireplaceStore on October 24, 2016

    Per the manufacturer, this log set is still available.

    By Lynda McAuley from Ontario on October 20, 2012
    When I run my gas GI3600 fireplace, I smell an odor that is very irrational to my throat and my lungs burn. Is this the result of the ceramic logs?
    By Collin C. - NFI Master Hearth Professional on October 22, 2012

    While uncommon, this natural vent fireplace insert can create an unpleasant smell under certain circumstances. One of the following issues may be occurring:

    1. The unit is new and the paint used in production of the unit is still curing. This is the most common cause of this smell and will dissipate with use.

    2. The ceramic logs are placed improperly. Please verify the logs are placed in the unit as specified in the owner's manual.

    3. The unit is experiencing a downdraft (spillage) when used. This can be caused by strong winds forcing their way down the chimney. A high wind cap can alleviate this issue.

    It would be best to check these issues in the order that they are listed. I will be happy to answer any questions you may have about further issues.

    By Steve from Toms River, NJ on October 10, 2014
    I have an original brick fireplace that I converted to a vent free natural gas log set from the home depot about 8 years ago during a second story add on to my house. I capped off the chimney right under the second story floor with a 1/2" thick steel plate and cement. Is there some sort of blower assembly I can add in to help distribute the heat? I would like to get rid of the little stand up fan I have on the side next to it to blow the heat away from the mantle because, without it, everything gets really hot. I have melted a few plastic holiday decorations.
    By eFireplaceStore on October 13, 2014

    While we do have grate heaters that can be used with vented logs, they are not intended for use with vent free log sets. The issue with using a blower with a vent free log set within a masonry fireplace is that even the slightest draft can cause wafting of the flames against the logs. This in turn causes some flame impingement, releasing CO and hydrocarbons into the air.

    By Faye from Ala on December 20, 2013
    We have logs that put out too much heat. Do you have logs that can be adjusted to a lower setting?
    By Collin C. - NFI Master Hearth Professional on December 20, 2013

    We do indeed offer vent free log sets that have an adjustable flame setting. However, even at the 50% flame adjustment mark, they will still be emitting at least 18,000 BTUs to the room, which is a considerable amount of heat. If you truly need heat from the log set at times, this would be the best option. However, if your fireplace has the ability to be vented, you may consider using a vented log set instead.

    By Al from Staten Island, New York on September 19, 2014
    Is there a model that has a glass front and a blower?
    By Chris C. on September 19, 2014

    These are strictly gas logs which a blower cannot be added, but we do list complete vent free fireplace assemblies which some do allow for the use of a blower and glass over the face of the unit. Please view some of these examples below:

    Is there a product that gives a wood smell for ventless fireplaces?
    By Kevin E. - Fireplace Specialist on December 26, 2012

    There are various aroma stones available that are activated by the heat of your fireplace. Unfortunately, we have none that features the scent of naturally burning wood.

    By David Stout from Mount Airy, MD on December 20, 2016
    I have direct vent Heatilalor fireplace (Model GCDC60) with decorative glass. Can I replace old gas logs with ventless gas logs without the decorative glass?
    By Brennan W. on December 21, 2016

    You can replace the logs with exact replacement logs, but you couldn't use aftermarket logs. Unfortunately, as we are not a Heatilator dealer, we do not have access to proper replacement logs.

    By Carl from MD on January 7, 2015
    What would cause fumes to come off of a ventless log natural gas fireplace?
    By eFireplaceStore on January 7, 2015

    Most vent free gas log sets will release an initial burn off odor during the first 3 to 4 hours of operation. However, if the set continues to release a noticeable smell when operating, there is likely an issue with log placement. The log placement instructions should be reviewed and a visible check made to ensure that flames are not hitting any of the logs directly. It is also important to service a vent free set on a yearly basis. Accumulation of dust, lint, or pet dander into the assembly can partially clog the air intake, releasing an odor.

    By Chip from Hoover, AL on July 10, 2013
    Our fireplace is in an outdoor area, but is not directly in the elements where rain can not get to it. Is it required to use the stainless burners?
    By Chris on July 10, 2013

    I would still suggest the use of stainless components due to the humidity and temperature changes that the burner and log set would be subjected to.

    By Frank from Boston, MA on May 19, 2013
    What size logs do you recommend for the Breckenridge VFD32FB2CL Deluxe Vent-free 32"?

    By Tyler M. - NFI Certified Specialist on May 20, 2013

    While most 18" ventless gas log sets will fit inside that 32" Breckenridge, some 24" sets can fit as well. Please see our full selection of ventless gas logs below, and let us know if you want us to verify proper fitting for a particular set:

    What else needs to be purchased if Ventless Gas Logs are purchased for an existing 36" wood fireplace?
    By Collin C. - NFI Master Hearth Professional on December 5, 2012

    If a new ventless log set is purchased, it will come as a complete assembly. The set will have all the needed components, including the decorative embers.

    Installation costs vary from region to region.

    By Pala from Maryland on January 12, 2013
    If I buy the vent free fireplace with remote control to turn the system on and off, will I still need to use the control knob, and if so where is it located on your systems? I have a vent free system already in my basement that is manual. I have to get on the floor to turn the control knob to turn it on to pilot, then adjust. I would like to purchase a system for upstairs but do not wish to get on the floor to turn it on.
    By Collin C. - NFI Master Hearth Professional on January 14, 2013

    Remote ready vent free fireplaces can be controlled from a remote or wall switch during the majority of operation. The pilot light will still need to be manually lit via the controls on the unit, but after this point the unit can be controlled completely by the remote. No further use of the unit's controls will be necessary unless you wish to turn the pilot completely off.

    By Rhett Ruscoe from Clarksdale, MS on December 26, 2012
    My fireplace is 36" front, 31" back, 22" depth. What size logs should I be looking for - 24" or 20"?
    By Collin C. - NFI Master Hearth Professional on December 26, 2012

    Per your dimensions, 24 inch ventless gas logs would offer the better fit.

    By Burt from PA on October 22, 2015
    What is the difference between vented and ventless gas logs/burners?

    By Brennan W. on October 22, 2015

    The difference between vented and vent free is efficiency. Vent free burners operate at an efficiency that allows them to only put off water vapor and carbon dioxide during combustion, so they can exhaust and draw combustion air from the room. Vented units can have a higher BTU output than vent free burners, but require venting which can cause heat loss. Vent free units are only meant to be used for 2-3 hours at a time as they put moisture into the air and can cause stuffiness in the room, while vented units can be run for as long as you would like.

    By Rita from Dover, Tennessee on January 8, 2014
    What would cause ventless gas logs to put out a soot film on the front of the fireplace?
    By Collin C. - NFI Master Hearth Professional on January 8, 2014

    Because vent free logs pull combustion air from the room and then return the heated air back to the room, they can produce a bit of a film over time. If the sooting is occurring over a relatively short amount of time, it is likely that the air shutter in the gas log burner assembly is becoming clogged and needs to be cleaned out. If this component is clogged with dust, dirt, or spider webs, in can cause the fuel mixture to become unbalanced, leading to the release of soot.

    By Customer from Dayton, NJ on October 22, 2012
    What is the difference between the remotes?
    By Tyler M. - Fireplace Specialist on October 22, 2012

    There are four different options for remotes with our Peterson Real Fyre Ventless Gas Logs. First, there are two options for the On/Off Automatic Pilot Kit log sets. The first is a basic on/off remote that simply turns the log set on or off, and the second is a deluxe on/off remote that turns a set on or off and also has a thermostat that can be set to operate the log set accordingly.

    There are also two remotes available with the Variable Flame Remote Pilot Kit. The first is similar to the basic on/off remote, but each time you press the "On" button, the valve gradually opens and the flame gets higher. As you press the "Off" button, the valve gradually closes and the flame gets lower.

    The second remote available for the Variable Flame Remote Pilot Kit has the added feature of a thermostat that will cause the valve to open and close as needed to meet the temperature you choose.

    By Dan from Amherst on October 10, 2013
    My ventless gas logs seem to be gassing off black soot. I recently painted and do not want to have the problem again. Any suggestions? We like heating the living room with our gas logs. They are in a vented fireplace, but we keep the vent closed.
    By Collin C. - NFI Master Hearth Professional on October 10, 2013

    Depending on the design and quality of the burner, some combustion byproducts can occur from vent free log sets. The best way to ensure a minimal amount of gassing is to verify the logs are set up in the manufacturer recommended configuration. Usually, mounting pins and grooves will only allow them to be set up a certain way, but flame should not be hitting the logs directly. Rather, it should wrap around them. Dust or lint that is drawn toward the logs can also cause the release of soot. It is important to service the log set annually to remove any dust or dirt that has built up inside the firebox and in the burner air intake.

    By Dan Blahnik from Whitelaw, WI on December 6, 2012
    I have a two-sided fireplace with a fireplace insert. We had it converted to a propane vented gas log a few years ago, but we get very little heat out of it now so we don't use it. I have been thinking about changing to a ventless gas log.

    1) Does this make sense? Will this give us more heat? 2) Could a ventless gas log be run with the vent closed? 3) Our insert also has doors and draws air from an outdoor vent. How would this work? 4) Finally, any suggestions on a log set?
    By Collin C. - NFI Master Hearth Professional on December 6, 2012

    A ventless log set would indeed offer a much greater amount of usable heat, compared to a largely decorative vented appliance. The ventless log sets are indeed designed to be operated with the damper closed and could use the outside air kit to draw fresh air for combustion. The doors would need to remain open during operation of the set.

    By Dan Blahnik from Whitelaw Wi. on December 15, 2012
    I have a Heatilator Model ST36C Fireplace. Can I use a ventless gas log with this unit ? I have read that Heatilator doesn't recommend using ventless logs in some of their fireplaces. Why?
    By Collin C. - NFI Master Hearth Professional on December 17, 2012

    Some models of fireplaces, including this model, do not allow for use of ventless gas logs because they are not insulated to stand up against the extra heat. Because the damper is closed during operation of ventless gas logs, no dilution air is pulled into the fireplace opening to cool it. This can cause the firebox to get significantly hotter than it would when being vented. In turn, this can cause clearances to the wooden framing behind the fireplace to be incorrect and will eventually lead to a fire.

    Overall, only if the appliance specifically states that it can be used with ventless gas logs can you do so.

    By Phyllis from Oklahoma City, OK on December 2, 2015
    I have gas logs in my fireplace at home. Do I have to open the flue when I use them?
    By Will M. on December 2, 2015

    If they are vented gas logs, you must absolutely open the damper while the logs are in operation. If they are vent free, opening the damper is typically only required by the gas log manufacturer when the mantel clearances cannot be met.

    By Keith from Springfield, VA on December 13, 2013
    Can I buy just the burner assembly and not the entire log set for a 24" natural log set?
    By Kevin E. - NFI Certified Specialist on December 13, 2013

    We currently only list our ventless logs as complete sets - both burners and logs. This is due to the highly specific way ventless units must operate. However, if you currently have a set of Peterson ventless logs and can reply with the model information, we can quote you the appropriate burner.

    By Steve Mills from Massapequa, NY on December 16, 2016
    I currently have a NG ventless fireplace that is about 15 yrs old. As I'm sure you've heard a thousand times, the unit emits an unpleasant odor that prevents us from using it. I have been reading recently that many new gas log sets are made with a catalytic converter system. Are any of the replacement log/burner sets you offer equipped with such a system.
    By Will M. on December 19, 2016

    Our recommendations will differ depending on if this is a ventless fireplace or simply a wood burning fireplace with ventless gas logs installed. If this is a fireplace, the only option will be complete replacement. If this is a gas log set, upgrading the system to a model with refractory ceramic logs may remedy the issue, so long as there are no pre-existing issues that will cause an odor with any ventless gas log set (high traffic area, ceiling fans or candles burning). With older, ceramic fiber logs, this lightweight, porous material will break down over time and hold a smell that will not go away unless the entire system is replaced. Also ventless gas hearth systems are not recommended for anyone who is sensitive to smell.

    By David from Waterville, PA on November 15, 2013
    Do the pilots stay lit on all of your ventless log sets? I am going to use this set infrequently and I am not sure about leaving the pilot lit all the time. Also, I'm not sure I want to leave the pilot on when I am away from home for a week at a time.
    By Tyler M. - NFI Certified Specialist on November 15, 2013

    Most of our ventless leg sets do indeed feature a standing pilot light. However, the sets that feature the Electronic Pilot Kit do not; these use a battery-operated ignition system that eliminates the standing pilot. You can use the search options on the left-hand side of this page to select "Electronic Remote Pilot" from the "Pilot Type" menu to see these log sets.

    By Blinda from AZ on April 6, 2014
    We are building an outdoor fireplace and want to use the ventless logs. The box is going to be sealed with concrete blocks and fire bricks on all interior sides so there is no flu. There will be a natural gas burner installed to be lit manually only. I don't think we need the remote control or the pilot light. There will be a key which turns the gas on to light it. That being said, can we just order the log set with the grate and is that all we need? What would you recommend for our situation?
    By Collin C. - NFI Master Hearth Professional on April 7, 2014

    By your description, you can indeed purchase just a log grate and a set of refractory logs to be used in your fireplace. For outdoor applications, it is ideal to use a stainless steel grate, as it will last much longer in the humid outdoor air. .

    By Steve from Atmore, AL on December 16, 2012
    I have a Monessen MCUF42D vent-free firebox (openings: 38.5" front, 30.25" rear, 16" depth, 26" height), an Ambiet Technologies RCT remote, and am set up for propane / LP gas. Which vent-free gas log sets (complete with logs, burner, millivolt valve, grate, etc) will work with my firebox and remote?
    By Collin C. - NFI Master Hearth Professional on December 17, 2012

    One popular option for your size of fireplace is the Real Fyre 30" Charred Frontier Oak Ventless Propane Gas Logs Set with Variable Flame Remote Pilot Kit. Another, lower cost option would be the Real Fyre 24" Golden Oak Designer Ventless Propane Gas Logs Set with Variable Flame Remote Pilot Kit. Both of these sets offer the ability to use your programmable remote and will fit your fireplace properly.

    By TaMara from Chicago, IL on January 14, 2013
    Are there options to purchase just the logs for a ventless fireplace? The logs that came with the unit are damaged and cant be used and I would like to figure out how to get just the logs or figure out a creative way to fill in the area without purchasing an entire unit.
    By Tyler M. - Fireplace Specialist on January 14, 2013

    Availability of replacement logs for your firebox will depend on a couple things. First, is your unit a vent-free firebox and separate vent-free log set, or did it all come together as part of a vent-free fireplace system (with box, burner and logs all included). If the former is true, you can replace your logs with a ventless gas log set. If the latter is the case, please reply with your manufacturer and model information and we can research availability of replacement logs for your unit.

    By Allen from VA on August 21, 2013
    Does vent-free gas fireplaces have only a gas connection and no other openings for a chimney or other vent connection?
    By Collin C. - NFI Master Hearth Professional on August 21, 2013

    Manufactured (metal) vent free fireplaces do indeed lack a chimney or external vent of any sort. They will recirculate and heat room air, using a precision burner system that avoids releasing harmful amounts of carbon monoxide into the room.

    Vent free gas logs can also be purchased and installed into an existing firebox. If the firebox is a model that has a chimney, be it masonry or manufactured, the chimney must still be present and in good working order. This is because the damper is not an air tight seal and some heat will escape. As such, the chimney must be in place to funnel it safely out.

    By Nikki from Ojai, CA on October 23, 2012
    Can ventless gas logs be used in California? We currently have a natural gas-jetted wood-burning fireplace and would like to use the faux logs but don't want all the heat to be sucked up the chimney flue due to an open damper.
    By Kevin E. - Fireplace Specialist on October 24, 2012

    Unfortunately, no. The state of California prohibits the installation of vent-free gas appliances. An alternative would be a direct vent insert. This option would require the relining of your chimney, though.

    By Jay from Conway, AR on October 19, 2013
    I currently have a vent-free fireplace and would like to upgrade my set to a remote/ thermostatically controlled set. The logs have been broken, so I just want a new set. The fireplace is a corner fireplace measuring 32" (front width), 26" (back width), 16" deep, and 30" high. Can you recommend a complete replacement set?
    By Collin C. - NFI Master Hearth Professional on October 21, 2013

    Based on your dimensions, one of our most popular vent free sets could be used. The set is the Real Fyre 24" Charred Frontier Oak Ventless Natural Gas Logs Set with On/Off Remote Pilot Kit. This set can be purchased with a thermostatic remote control that can be used to maintain the room temperature. It is important to note that this set is complete with the burner system and can be installed into a vent free firebox that does not have the burner system as an integral component. If your vent free firebox came with the burner as part of the unit, this set should not be used.

    By Mary from New Bern, NC on November 20, 2014
    We are converting our fireplace from propane to natural gas but I'm not sure which pilot type to use. What are the differences between them? What would you suggest? Also, do natural gas logs put out a lot of heat? We have a ventless fireplace.
    By eFireplaceStore on November 21, 2014

    Propane and natural gas log assemblies will produce the same BTU output, when looking at the output between the same models. Propane burners will have a smaller burner orifice, as propane gas has a higher BTU potential than natural gas.

    All pilot assemblies used with vent free logs are safe and have a built in shutdown system that will turn gas off to the valve if the pilot flame is lost for any reason. The most basic type of pilot is a manual pilot or what is commonly known as a "safety pilot". This system allows only manual control of the burner, with some systems offering 3 step flame height adjustment. A control knob is located on the burner assembly. Remote or millivolt pilot assemblies will allow you to control the unit from a light switch or remote control. There are also various other remote assemblies that allow flame height adjustment, in addition to the ability to control the unit from a remote.

    I want a ventless gas log set with a blower. What is the best option for me?
    By Tyler M. - Fireplace Specialist on February 12, 2013

    None of our ventless gas log sets have a blower option. If you have a manufactured wood-burning fireplace, there may be a blower available for that model that you can use in conjunction with a ventless log set.

    Where can I find the efficiency rating percentage for gas logs? I have the Pyromaster UN-24IL un-vented set. My HVAC guy says they are about 40% and my gas pack is about 70 (installed 1997). I have a friend with older logs too. He heats only with those.
    By Tyler M. - Fireplace Specialist on November 29, 2012

    Our Real Fyre ventless gas logs are 99.9% efficient, as the heat has nowhere to go but in the room where you are burning the log set.

    By John from CO on October 29, 2014
    I am replacing a vented natural gas log set that is controlled by a wall switch. Can I use a regular Safety Pilot system instead of a remote control?
    By eFireplaceStore on October 29, 2014

    Certainly. The wall switch is simply completing a millivolt circuit, so the switch could be disconnected and a manual valve used instead.

    I am looking for gas logs for my Majestic BUF400 fireplace that have a thermostat and also run off of propane. What would you suggest?
    By eFireplaceStore on February 19, 2015

    There are a vast number of vent free log sets that we carry that will fit this unit, but the 24 inch width is one common detail. Some of the most popular sets we offer in LP and with the option for a thermostat are the Empire 24" Ponderosa Refractory Ventless Propane Gas Log Set and Millivolt Slope Glaze Burner, the Empire 24" Charred Oak Ceramic Fiber Ventless Propane Gas Log Set and Intermittent Slope Glaze Burner, and the Real Fyre 24" Charred Frontier Oak Ventless Propane Gas Logs Set with Variable Flame Remote Pilot Kit.

    By Barbara from Atlanta on August 3, 2014
    Can ventless logs replace natural gas logs?
    By eFireplaceStore on August 4, 2014

    Both vented and vent free logs are typically available in natural gas or propane fuels. I'm assuming that you currently have a vented set that is fueled by natural gas and want to convert to vent free. If this is correct, I will need to know the front width, rear width, depth, and height of your fireplace opening. This will help me to determine the proper size of set for your needs.

    By Steve from Richmond, VA on December 3, 2013
    My mechanical fireplace measures 30" at the opening front width and 20" at the back wall width. The depth is 16 inches and height is 16 inches. What is the largest set that will fit and work properly?
    By Collin C. - NFI Master Hearth Professional on December 3, 2013

    Unfortunately, a 24 inch set is slightly too large for your application, so a 20 inch set would have to be used. An example is the Real Fyre 20" Golden Oak Designer Ventless Natural Gas Logs Set with Safety Pilot Kit. This unit will offer enough supplemental heat to warm approximately 900 square feet.

    By Lisa from VT on February 3, 2015
    I have older logs from my previous fireplace. Will I be able to reuse them with a ventless system?
    By eFireplaceStore on February 3, 2015

    Unfortunately, no. Vent free log sets and burners are very specific to one another. As such, the logs and burner can only be purchased and installed as a complete set. This will ensure that the system does not release harmful soot or carbon monoxide into the room.

    By Mary from NJ on November 5, 2013
    Can you insert ventless gas logs or insert into a wooden entertainment center made for electric inserts?
    By Collin C. - NFI Master Hearth Professional on November 5, 2013

    Unfortunately, no. The wooden entertainment centers are specifically tested and listed for use with electric fireplace inserts only. Gas inserts release a great deal of heat that requires them to have greater clearances to combustibles. As such, they can only be used with purpose built mantels or built into a surrounding wall enclosure.

    By Ed from NJ on August 28, 2014
    I want to replace my ventless gas logs with new with thermostat remote. The metal fire box is 28 1/2 inches in the front, 21 inches at the back, and 13 1/4 inches deep with a 20 inch height. What size and type of ventless gas logs would work for me?
    By eFireplaceStore on August 28, 2014

    Based on your dimensions, most 24 inch sets will work for your application. An example of a popular set with thermostatic remote capabilities is the Monessen 24" Mountain Cedar Ventless Natural Gas Log Set with On/Off Remote Pilot Kit. The remote ready pilot assembly allows the use of a thermostatic remote such as the Ambient RCST Standard Thermostat On/Off Remote Control.

    By Kenneth Ling from Lola, Kansas on January 8, 2017
    We have a set of 24" ventless gas logs, and would like to know if they could be fitted with a remote.

    By Brennan W. on January 9, 2017

    I will be happy to look into this for you. If you could, please provide the manufacturer and model number of your log set.

    By Jaycee from Mt. Laurel, NJ on February 4, 2013
    I have ventless ceramic logs in my wood-burning fireplace that was converted more than 15 years ago. Lately I have noticed a residual soot around the fireplace brick and walls nearby. The unit still works well. Does this mean the set needs to be replaced? If so, why?
    By Collin C. - NFI Master Hearth Professional on February 5, 2013

    Increased output of soot and combustion byproducts can mean several things. Has the unit been serviced recently? Because ventless logs draw all of their combustion air from within the room, eventually the burner orifice and air shutter can become clogged with lint or dust. It is recommended to have the unit cleaned on a yearly basis to prevent sooting.

    If the unit was serviced recently, please verify the logs are setup in the original configuration. If the logs are placed in a position directly over the flames, sooting can occur. When the burner is serviced, it is also recommended to have an inspection of the burner tube done, as they can corrode over time.

    By Paula from Nocona, Texas on December 9, 2013
    I have a silly question for you. We have a traditional fireplace that has a flue that can be opened. Can we have ventless logs, or will it require us to have a log set that requires venting?
    By Collin C. - NFI Master Hearth Professional on December 10, 2013

    This is actually a good question and one that comes up often. If the chimney does have a working damper and is in good shape, you have the choice of using a vented or vent free set. The damper can be closed down most of the way with a vent free set, allowing the heat to circulate in the room for greater efficiency. In the event that you would like to operate the set, without incurring the extra heat, the damper could be fully opened.

    By Shannon from New Orleans, LA on May 21, 2014
    My house originally had a coal-burning fireplace. It does not appear to have a damper or a lining. What is the best way to close off the top and bottom of the chimney so that a ventless log set can be used without introducing dampness into the chimney and losing heat up the chimney?
    By eFireplaceStore on May 21, 2014

    In your case, it may be best to use a vent free insert, as opposed to a vent free log set. The insert will be a completely sealed and self contained metal chassis, which will prevent any heat from escaping to the chimney. By code, if the fireplace has any sort of chimney, it cannot be sealed off when using vent free logs. While I have seen fireplaces sealed by use of a fabricated metal pan, this is technically not an acceptable solution.

    By bill from Scottsdale, AZ on November 30, 2012
    What is the largest ventless size? My opening is 50".
    By Collin C. - NFI Master Hearth Professional on December 3, 2012

    The largest vent-free set we carry is 30 inches in width. The reason for the size limitation is linked to the BTU output limitation of 40000 BTUs for a vent-free log set. Any larger burner would yield a flame that is too low to be appealing or realistic. Any larger log set available would be in a vented variety.

    By Paul from Pittsburgh Pa on March 11, 2014
    We are interested in the ventless gas logs but are concerned about the safety of a 100+ year old fireplace. We plan to bring in a new gas line, repair any brick work necessary and seal off the flue/chimney with fire brick but would like to leave the existing firebox as original as possible. We are using professionals for the work. Anything else we need to consider? If it is structurally adequate, are we okay?

    By Chris on March 11, 2014

    Being that vent free log sets emit much less heat than wood burning fireplaces do, a basic inspection to ensure that the fireplace, and chimney system are sound and safe would be sufficient to allow a vent free log set to be installed. Having professionals on site takes out a lot of guess work being that they can visually inspect and make needed repairs to the fireplace.

    By Janice Eason from Tuscalooosa, AL on December 8, 2016
    Are there electronic ignition retro fit kits for ventless gas logs? My gas logs are hard to turn on and I need the most simple way to turn them on that doesn't require you to crawl into the fireplace to turn them on.
    By Brennan W. on December 8, 2016

    We will be happy to look into replacement panels for your unit. If you could, will you please provide the manufacturer and model number of your fireplace? We look forward to your response.

    By Stephen from NJ on February 15, 2017
    How does the unit work, so as to not need to be vented?
    By Brennan W. on February 15, 2017

    These units operate at a high enough efficiency to put off only water vapor and carbon dioxide during operation.

    By Bob from Lockport, NY on January 27, 2015
    What is the difference between refractory log sets and ceramic fiber log sets? I'm looking at a Vail Premium 32" ventless fireplace. Which model would you recommend? What are the pros and cons between the 2 different types?
    By Chris C. on January 27, 2015

    Refractory logs are superior to ceramic fiber logs as they do not break down over time unlike ceramic fiber logs. Secondly, ceramic fiber logs are much more fragile making cleaning and maintenance a delicate process. Refractory logs will continue to hold and radiate heat for some time after the burner has been extinguished similar to the side of a brick wall which has been exposed to the sun for the majority of the afternoon. If you are in search of a 32" fireplace, I would suggest utilizing a firebox, such as the Empire Breckenridge VFD32FB0L Deluxe Vent-Free Louvered Gas Firebox - 32" along with an 18" log set of your choosing. With a firebox and log set purchased separately, if for any reason down the line, the log set needs to be replaced and replacement components are no longer available, a replacement log set and burner could be installed. Whereas, if a vent free fireplace in which the burner and log set are proprietary to that fireplace, replacement components could be harder to come by at a much later time. Pairing a firebox and log set may be slightly more expensive on the front end, but is well worth it in the long run.

    Ceramic log sets have one "pro" which sets them apart from refractory logs. While the burner is in operation, the ceramic logs will commonly have a section of the log placed closely to the burner tube allowing the log to glow as if it were a true wood log.

    By Lucy from Marshfield, MA on October 30, 2014
    My fireplace measures:
    width of FP opening - 58"
    height of FP opening - 39"
    width of FP rear - 38"
    depth of FP floor - 22"

    What size do you recommend? I am thinking of the RealFrye G10 Charred Aged Split Oak 30". Does that sound appropriate?
    By eFireplaceStore on October 30, 2014

    This set would indeed be the correct model to use and is the largest we offer. Your fireplace opening is quite large for the size of the 30 inch set, however the BTU limitation that is in place for vent free appliances prevents a larger version from being offered.

    By Donna from Charleston, SC on December 10, 2014
    We are looking at ventless gas logs for natural gas to replace some gas logs that we have had with propane for about 20 years. We will be hiring a plumber to convert our appliances to natural gas and wondered if there is anything special about installation that we need to worry about. With the plumber's help, should we be able to install them ourselves or do we need to hire someone to install them?
    By eFireplaceStore on December 11, 2014

    As long as the gas line is currently in position, changing fuels will not be an issue for a vent free log set. As you know, vent free systems cannot be converted, so installing the new natural gas burner will be fairly simple. The supplied gas line will connect to the existing pipe stub already in the fireplace. This is a job that your plumber could very easily handle.

    By Randy from Birmingham, AL on February 27, 2017
    I have a corner cabinet unit with ventless natural gas logs and need to change to using propane gas logs. Where can I find them?

    Can all of your ventless propane log sets be controlled electronically with the necessary adapter?
    By Kevin E. on January 10, 2015

    Only our remote-ready units can be controlled electronically. This would include both the variable flame sets and the on/off variety. The units listed as "Safety Pilot" can only be controlled manually at the log set.

    By Keith on November 9, 2012
    I live in a house that was built around 1946. I have a gas fireplace that's 30.6" front, back 28.6" and 9" deep. It's non vented. I would like to put gas logs back in it. Can you help?
    on November 9, 2012

    Based on the depth of your fireplace, it definitely seems like this must be a Victorian styled firebox. Unfortunately, I do not have a log set that could accommodate the 9 inch depth. The only vent free units I offer in the reduced depth category are coal baskets. For reference, you may view one of these units at the link below: Coal Basket These are meant to be used in conjunction with a decorative coal basket front, which is typically installed in reduced depth fireplaces such as yours.

    By Linda on November 9, 2012
    Should the pilot light be turned off during the summer months or would you recommend not keeping it lit and opening the flue for venting the excess gas? In the winter, would it be okay not to keep the pilot light lit then throwing a match in whenever you wanted a fire?
    on November 9, 2012

    Generally, we recommend turning off the pilot for the summer months and re-lighting the first time you intend to use the fireplace. You would then keep it lit until you no longer need or want to use the fireplace, heading into the next summer.

    What size logs do you recommend for the Breckenridge Deluxe 36"?
    By Tyler M. - NFI Certified Specialist on March 14, 2013

    The Breckenridge Deluxe 36" fireboxes are best suited for our 24" Real Fyre ventless gas log sets. However, you will need to double-check the required dimensions to ensure proper fitting before ordering.

    By g from Massachusetts on February 16, 2013
    I am interested in a Peterson 30" G-18 vent free evening charred gas log set, but I am confused about the remote options, There are no descriptions of what they do, and what is electronic ignition? Does that come with variable flame adjustment on remote? What controls the flame height?
    By Tommy H. on February 18, 2013

    A SPK or safety pilot kit is a standard pilot offering no remote compatibility. An APK or automatic pilot kit comes in two versions: On/Off remote ready or Variable Flame remote ready. An EPK or electronic pilot kit will ignite the fire without the need for a standing pilot light using piezoelectric ignition and can also use an on/off remote.

    There are typically two remote types: standard and deluxe/thermostatic. Thermostatic remotes will turn the unit on or off depending on the temperature where you leave the remote.

    By Eileen from Greer, SC on October 14, 2013
    I would like to add a gas ventless log to my fireplace. I have moved into a house which was built in the 1940's. The fireplace measures 20.5" in front, 18.5" in the back, and 9" wide. There is a copper pipe with a red on off knob coming up from the floor of the fireplace. Can you help me?
    By Collin C. - NFI Master Hearth Professional on October 15, 2013

    Based on the dimensions of your fireplace, it was likely constructed as a coal burning unit and will allow a very limited selection for gas logs. The smallest set that we carry is the Real Fyre 16" Valley Oak Ventless Natural Gas Logs Set with Safety Pilot Kit. The only issue with this set is that it requires 1 inch of additional depth over what you have. This may not necessarily be an issue if the fireplace has a hearth that will allow the very front of the log set to protrude onto.

    Another option would be to use vent free coal burner, such as the Rasmussen Vent-Free Natural Gas Burner with Realistic Coals. As you can see by the appearance, it is not meant to be used by itself. The burner should be placed into a decorative coal basket or used with a fender. Some coal burning fireplaces retained their original fenders and this could be used to conceal the burner, if your fireplace still has the fender.

    By ron pearce from Flemington, NJ on November 16, 2012
    I'm interested in a ventless gas log for my wood-burning fireplace. It would need to be small: my fireplace takes 18 inch logs maximum, and burns propane. Do you have a product that can run using 20 or 30 lb. propane cylinders?
    By Collin C. - NFI Master Hearth Professional on November 16, 2012

    Our vent free gas logs can use down to a 20 pound propane cylinder, but this will limit the amount of time the unit will be able to burn before requiring time to vaporize more fuel. The larger the cylinder that can be used, the better.

    By Pam from WA on July 25, 2013
    How do I know if I need vented or ventless gas logs?
    By Collin C. - NFI Master Hearth Professional on July 25, 2013

    If your fireplace is complete and the chimney is in good working order, either system can be used.

    Vented logs offer a high flame and BTU output, giving the most realistic appearance. The logs are also placed more naturally, further enhancing the look. However, these systems are primarily for looks and only give a small amount of supplemental heat.

    Ventless gas logs have a lower flame and 40,000 BTU limit. However, all heat is pushed directly into the room, making them an excellent heating appliance. The logs do not work well in small spaces, humid environments, or dusty rooms. The sets use room air for combustion and introduce moisture back into the room. Small areas can cause oxygen depletion and excess moisture.

    By Linda Murray from Irwin, PA on December 19, 2016
    I need an 18" log for the back log, a 19" log in front, and 2 1/2" wide. Do you have those available?
