I have a Marco model 794019C that I want to replace. It works but is only 22000 BTU. I want 40000 to 60000 BTU. I have a wall on/off switch, which is fine.

What are the easiest to install choices that I can order from you? I like as much flame as possible, too.
By Tyler M. - Fireplace Specialist on November 26, 2012

Answer:
Here are a few direct vent options for you to consider, along with their BTU ratings:

Napoleon HDX40 Direct Vent Clean Face Gas Fireplace with Black Doors (40,000 BTUs)

Napoleon Madison Direct Vent Gas Fireplace (43,000 BTUs)

Napoleon Dream Direct Vent Gas Fireplace (50,000 BTUs)

Please see the owner's manual for each of these fireplaces for sizing and framing information.
By Collin C. - NFI Master Hearth Professional on November 26, 2012

Answer:
We carry several high BTU models that are both reliable and offer a very good flame presentation. One such model is the Monessen Covington Clear View Direct Vent Gas Fireplace with Millivolt Controls - 48 Inch.

Another good alternative is the DDI Citadel 36" Natural Gas Cool Touch Direct Vent Fireplace. Many of the other high output units are substantially larger, as this is common once a unit is greater than 35,000 BTUs.

I am building a new home and someone has given me a firebox that was for burning wood. I would like to install it for a gas log, is that feasible? It did have a gas starter for for the wood. Would I need a glass door to use a gas log?
By Tyler M. - Fireplace Specialist on January 9, 2013

Answer:
Yes, if the fireplace has been tested and listed for gas logs. A glass door is not required to have a vented gas log set. If the fireplace has functional chimney pipe installed that runs over the roof, you can get a vented gas log set. If you do not have a working chimney, you may be able to use a ventless log set. If you prefer, please reply with your full fireplace dimensions (front width, rear width, opening height, depth, etc.), as well has how you want to control the unit (on/off remote, variable flame remote, wall switch or manual), and we will be happy to offer some recommendations.

Can a vented natural gas log be converted to a vent-free LP log?
By Tyler M. - Fireplace Specialist on February 7, 2013

Answer:
No, this conversion it not possible. We recommend any of our ventless propane log sets. Please see our full selection below: Ventless Gas Logs

Please note the fuel type, as vent-free appliances cannot be field-converted.

By Brion Blanc from Indiana on November 16, 2012
Can I buy replacement parts for gas log sets, specifically the valve leading into the burner? The gas company came out and identified a leak in the valve, though they could not determine the exact spot. Or am I just better off paying for a whole new set? I want to save money but I also don't want to blow up my family.

Info I found on the unit said:
RH Peterson
Real-Fyre
SV-12
764-202 E1
1/2 PSI Max
175 F Max
9403
By Kevin E. - Fireplace Specialist on November 16, 2012

Answer:
The SV-12 is the actual valve body of the Peterson SPK-20 pilot assembly. This pilot assembly is no longer readily available. However, the SPK-26 is a perfect replacement. We offer these in both natural gas and propane applications.

By Jim from Angola, NY on November 10, 2012
I have a prefab Heatilator fireplace which was vented through the roof four years ago. I have put in a pellet stove insert and blocked the roof vent and vented the stove out through the wall. My pellet stove is not working. My wife wants to change to gas logs. Can this be done by removing the pellet insert and installing gas logs vented out the wall or not vented at all? I have since put on a new metal roof and covered vent
By Collin C. - NFI Master Hearth Professional on November 12, 2012

Answer:
Vent-free logs can be used in a prefabricated fireplace, however the chimney system must be in place and functioning properly as some heat will escape to the flue. The flue must be a vertical system, as the escaping heat does not have the assistance of a fan, such as the pellet stove. The best option would be to extend your chimney system back through the new roof, then allowing the use of gas logs again.

Another option would be to use a gas fireplace insert. Vent free gas inserts are completely sealed and do not require the chimney system to be in place. However, use of the insert would depend on the size of your firebox opening.

By Ken from Wilmington, NC on January 20, 2013
How do I know if I have a vented or ventless firelog system?
By Collin C. - NFI Master Hearth Professional on January 21, 2013

Answer:
I would first check any data plate numbers or part numbers that are affixed to the unit. This information will likely tell which you have.

Vented systems will have a high flame and most will have a large ember bed. The logs will usually not have locating notches or pins. Vent free systems will have a low flame with a thin layer of ember material, if any. The logs usually have notches to position them properly.

By Ronnie from Hot Springs , AR on March 1, 2013
How do you know if you have ventless logs, or logs that need venting?
By Tyler M. - NFI Certified Specialist on March 1, 2013

Answer:
We can identify this with the manufacturer and model information for the log set. This should be located on the burner itself or attached to it with a data plate.

By Beverly from Iva, SC on March 1, 2013
Which sets of logs are suitable for a see-thru fireplace? I am having one built by a contractor.
By Collin C. - NFI Master Hearth Professional on March 4, 2013

Answer:
Any of our R.H. Peterson See Thru Gas Logs could be used for this type of installation. Narrowing your search by the required fuel type, size, and pilot type will give you a more accurate group to choose from. Selecting vented or vent free will also help. Vented logs tend to have a high flame and BTU output, but are largely aesthetic. Vent free logs have a lower flame, but serve as a heating appliance for the room. If you have an idea on what dimensions the fireplace will be, I can assist in sizing the correct logs for your needs.

By zouheir from Seminole, OK on November 17, 2012
We are trying to convert our fireplace to gas. We have a vented unit that measures as following: the width halfway back is 28 inches and 15 inches deep. What size logs do we need? We need the plate for under the logs that has the pilot light. We would like to get one with a starter and be able to adjust the flame. Can you tell me which models work?
By Collin C. - NFI Master Hearth Professional on November 19, 2012

Answer:
Based on the width of your fireplace and your request for variable flame control, I would recommend using a 16 inch log set. One of our most popular sellers is the Real Fyre 16" Charred Oak Vented Natural Gas Logs Set with Variable Flame Automatic Pilot Kit. This unit can be controlled via a wall mounted switch or a remote control. If propane gas is needed, we offer the unit configured to burn this fuel as well.

By Darren from Kansas City, KS on November 26, 2012
I have a ventless fireplace system that was installed two years ago. When they installed it, the installers put down some steel wool-looking stuff that glowed like charcoal embers. That wool substance has sort of burned up and I'm wanting to replace it. What did they put down, and where can I get some?
By Collin C. - NFI Master Hearth Professional on November 27, 2012

Answer:
The material is commonly referred to as "ember glow" or another similar term. It is a ceramic fiber material that will indeed deteriorate over time and require replacement. Vent-free fireplaces must use a specific variety that does not give off harmful byproducts when heated.

By John from Enid, OK on November 11, 2012
I have a 35" x 26" see-thru metal cabinet which is vented and made by Best Fireplaces, Ft Worth, TX. It currently has a log starter pipe with wall key control. I would like to put in an electronic start natural gas burner. I already have the gas logs. What do you recommend?
By Collin C. - NFI Master Hearth Professional on November 12, 2012

Answer:
Based on your dimensions and ignition requirements, the compatible burner for your needs is the Real Fyre 24" G45A ANSI Certified Triple T SEE THRU Gas Log Vented Burner with Electronic Pilot Kit. Please keep in mind however, that this burner is made for use with R.H. Peterson refractory logs. We cannot guarantee the lifespan of other brands when used in conjunction with this burner.

Also, this size of burner will require a flue pipe that is at least 9 inches in diameter. The smaller 18-inch version may use an 8-inch pipe.

By Al from Lakeside, AZ on February 8, 2013
I have removed a vented gas log set and want to know if it is possible to install a vent-free set. My home is at an elevation of 6800 feet. I am told that the ODS which is essential for vent-free operation will not work at that elevation.
By Collin C. - NFI Master Hearth Professional on February 8, 2013

Answer:
That is correct. Vent free appliances are not recommended above 4,500 feet of elevation. Because of lower oxygen levels, the ODS will frequently cause pilot outage. A vented unit is the best type of appliance for higher elevations.

By Phil Gaddy from Newnan, GA on November 6, 2012
I've never had gas logs before. I have natural gas and I want to put them in an existing wood fireplace. What are my options? Do I needed vented or ventless?
By Tyler M. - Fireplace Specialist on November 6, 2012

Answer:
Choosing between vented and ventless is entirely up to you, as long as ventless logs are permitted by your local building code. For a brief summary of the differences, please see this explanation from our website:

Vented Gas Logs – Vented gas logs are to be used with an open chimney flue or damper. The decorative fire they produce is large and realistic, but does not work as a very efficient heating source, as most of the heat escapes through the chimney. To produce this realistic flame, the logs also use more gas.

Vent-Free Gas Logs – Ventless (or vent-free) gas logs do not require a vent, like a chimney, to operate. This means that most of the heat generated stays in your home, and may actually save you money on your heating bill. They’re also a much better choice for the environment, because the harmful by products are not released into the atmosphere. Some even have a thermostat to control the temperature.

However, the fire does not look as real as a vented gas log, and they add moisture to the air that can cause mildew if the proper precautions are not taken. Another major concern is that these logs use oxygen to burn cleanly, and if they are burned for too long without introducing clean air into the room they can pose a danger. It’s crucial to install a carbon monoxide detector into any room using vent-free gas logs.

By James Aschenbeck from Crestwood, KY on October 20, 2012
I have a majestic BR36 fireplace and am interested in a vent-free system. I would like to have a remote on/off with thermostat control if possible. Are there any sets that will fit this fireplace? The hearth dimensions are 33 1/4" wide, 15 1/4" deep, and 19 5/8" wide. The fireplace dimensions are 36 wide, 20 deep, and 22 wide.
By Collin C. - NFI Master Hearth Professional on October 22, 2012

Answer:
Based on the hearth dimensions of the BR36, a set of 24" vent free logs could be easily used in this fireplace. One popular set is the Charred Frontier Oak set. This unit features R.H. Peterson's high output G10 burner system with an on/off gas valve. A thermostatic remote can be selected as an option from the menu on the item page.

By james clauss from Santee, CA on December 13, 2012
I have a presidential series (gl4000E/EP) vented natural gas unit. Is it possible to put in a fan kit for better heating?
By Collin C. - NFI Master Hearth Professional on December 13, 2012

Answer:
Unfortunately, a fan kit is not able to be used with the GL4000E/EP. Unlike the GL4100, this model does not have provisions for the kit to be installed, as it is lacking the blower compartment and louvers that are needed to circulate air.

By Kim from Huntington Beach, CA on April 3, 2013
I live in a small apartment that was built in 1972. I have a gas burning fireplace, that I think is vented. It ignites with a light switch on the wall. The burner control is shot and I need to fix the control or replace the unit. Which is the better option? And what will I need?
By Collin C. - NFI Master Hearth Professional on April 4, 2013

Answer:
Per your attached photos, it appears what you have currently is a B-vent gas fireplace with a millivolt type of gas valve. The standing pilot/millivolt valve is what allows you to control the unit with the light switch. There are many universal millivolt gas valves on the market and we may carry one that could be used in place of the current valve. In order to verify this, you will need to provide any model information you can find from the valve itself.

By Mike from Washington, MI on November 6, 2012
Our home came with a three-sided Superior vented gas fireplace between our kitchen & great room. We need a set of replacement gas logs for it. Superior is no longer in business, but can I get a 30" x 18" gas log set that will work in it?
By Tyler M. - Fireplace Specialist on November 6, 2012

Answer:
If your model is tested and listed to accept gas logs, we do have several see-thru gas log sets that may interest you.

By Wm. Neill from Jacksonville, FL on October 30, 2012
Do you have any gas logs for a fireplace open on both sides?
By Tyler M. - Fireplace Specialist on October 30, 2012

Answer:
Yes, we have a variety of see-thru (two-sided) gas log sets, available in both vented and ventless configurations. You can see all of them here.

By Carol Dybowski from Grant Park, IL on October 21, 2012
Can I replace my gas logs with any logs I choose?
By Tyler M. - Fireplace Specialist on October 22, 2012

Answer:
No, it is not a good idea to install logs that are not made by the manufacturer of the burner that you currently have. If you have ventless or vent-free gas logs, you will need to get identical replacements. If it is a vented set, there may be other log styles available for you.

By Delre Smith from Champaign, IL on October 30, 2012

By John on November 9, 2012
Hi, I bought an old Victorian cast iron insert fireplace which I want to convert to gas fire. What exactly do I need to buy from you? (logs, burner, et cetera)
on November 9, 2012

Answer:
This would indeed be a suitable item, however the cast iron insert would indeed need to be positioned into an existing masonry fireplace or pushed into an acceptable manufactured fireplace with a properly functioning chimney. These types of inserts cannot be used without the chimney. Do you have an existing fireplace that the insert will be used with? If not, I will be happy to quote a suitable fireplace and chimney system for you. Please let me know.

By Jerry on November 9, 2012
Is there an appropriate vented gas log on which I could burn wood sometimes? Is it a good idea? Commonly done by some folk?
on November 9, 2012

Answer:
All of our wood-burning fireplaces can also be used to install gas logs inside. To answer your question, yes, this is something that is very common. The key is to get a "wood-burning fireplace" that is listed to burn wood and vented accordingly with Class A chimney pipe. These units have knock-out plates on either side to allow a gas line to run in and connect to a gas log set. Please see our full selection of wood-burning fireplaces here: Wood Burning Fireplaces Remember, these must be vented with Class A pipe, and different models of fireplaces require different types of Class A pipe. We do carry all the appropriate piping for any of these units. If you have any questions about venting the fireplace, please let us know. We also carry the full line of Peterson Real Fyre gas logs as well: Gas Logs Please let us know if you have any additional questions.

By Donna on November 9, 2012
I am interested in buying a gas log set for my see-thru fireplace. My dimensions are 32" wide, 27" high and 26" deep. I will be using propane fuel. I want to make it as easy as possible for the whole family to operate, so I need advice as to what pilot kit to purchase.
on November 9, 2012

Answer:
For a vented see-thru unit, you can get a 20" log set with an automatic pilot kit. These kits will allow you to use a hand-held remote or a wall switch to operate it. Please see one example below:

Log Set 1.

Here is another log design with the same control features:

Log Set 2.

Both of these sets require 32" width in the middle, which is exactly what you have.

By Gregory on November 9, 2012
I'm looking at gas logs. My fireplace is fully vented and already has a natural gas line run to it. The front width is 30”; the back width is 26”; the middle width is 28” and the depth of the fireplace is 14 1/4”. It seems that every set I look at needs a middle width of 30”, or if a width less than that then it needs a depth usually about 20”. What gas log set would fit?
on November 9, 2012

Answer:
The following types would fit in your existing fireplace: 16" Match light sets 16" Safety Pilot Kit sets (manual on/off gas valve) 16" Remote Ready sets. This includes the on/off valve, variable flame valve, and electronic (spark ignitor) on/off valve. 18" Match light sets 18" Safety Pilot Kit sets

By Pete on November 9, 2012
I have a DESA Direct Vent Propane insert. The components were rusted out so I removed them. The insert itself is in good shape. What are my options?
on November 9, 2012

Answer:
Unfortunately, the logs and burner assembly of a direct vent insert can not be swapped out with another burner assembly. A standard vented gas log set would not be an appropriate fit for your appliance. Your best bet would be to search for an exact replacement for the components you pulled out of the insert.

By Susan from Phoenix, AZ on March 5, 2013
Looking for fire pit logs about 7-9 inches long. I need about 4 single logs.
By Tyler M. - NFI Certified Specialist on March 5, 2013

Answer:
While we do sell some decorative gas logs, they are intended for use only with R.H. Peterson Real Fyre vented gas log burners. Please see them below:

Real Fyre 9" Oak Branches - Two in Box

Real Fyre Bonus Designer Logs - Set of 2

By Craig from Los Angeles on November 7, 2012
My fireplace dimensions are: front width – 29", back width – 21 ˝", depth – 16 ˝". I am looking for a vented gas log set. I do not need the burner, just the logs. I'm also looking for least expensive.

By Kevin E. - Fireplace Specialist on November 7, 2012

Answer:
Per your fireplace dimensions, I would recommend either an 18" or 20" log set. This recommendation is based upon what burner would be appropriate for your application.

Our least expensive style is our Post Oak log set.

By Joseph Oliveri from Brick, NJ on November 7, 2012
I have a propane ventless fireplace. Can I convert to natural gas logs without changing the fire box? The company is Desa International. The measurements are: h 32 3/4, front w 34 5/16, depth 16 11/16.

By Kevin E. - Fireplace Specialist on November 7, 2012

Answer:
You would only be able to convert to a natural gas appliance if the log set and burner assembly are separate from the Desa firebox in which they are installed. If firebox, burner and logs are one comprehensive assembly, conversion to a new set is usually not possible.

By stephen cline from Ashville, Ohio on November 20, 2012
I have a vented gas log fire place. The damper is opened, but I still have a smell but not like propane. Could you give me some suggestions?

By Collin C. - NFI Master Hearth Professional on November 20, 2012

Answer:
Do you notice the smell only when the log set is burning, or do you get the smell when the damper is open and the log set is not burning? Was the fireplace used for wood prior to installing the log set? If so, was the chimney swept prior to installing the log set?

By joyce from Richmond, VA on October 31, 2012
Propane or natural gas?
By Collin C. - NFI Master Hearth Professional on October 31, 2012

Answer:
The gas log sets we carry are available in both natural gas and LP. In order to narrow down to the correct fuel type, you will first need to select the "vented" or "ventless" gas log category. You may then narrow down your selections by fuel, size, and pilot type by using the selection bar on the left side of the page.

By Bill cooper from Chattanooga, TN on November 20, 2012
Can you get a set of ventless gas logs with both a remote and thermostat? Can the logs' pilot light be controlled with the remote?
By Tyler M. - Fireplace Specialist on November 20, 2012

Answer:
Our ventless gas logs do offer the option to add a hand-held remote control that offers both on/off functionality as well as a thermostat. However, none of our sets control the pilot light itself. We have millivolt valves that have on/off and variable flame control that utilize a standing pilot and an electronic pilot kit that eliminates the pilot light altogether.

By dale wohlford from Hutchinson, KS on December 28, 2012
We have a wood-burning fireplace and are considering buying a gas log. What are the benefits of ventless, and are they safe?
By Tyler M. - Fireplace Specialist on December 28, 2012

Answer:
Ventless logs are indeed safe, but there are a few factors to consider before purchasing. Please read our article with plenty of information about ventless gas logs and how they compare to vented gas logs; you can read it by clicking the following link:

What to Know When Buying Gas Logs

By Jon from Virginia on January 23, 2013
About how long should I expect my Monessen Covington direct vent fireplace to take to burn off the manufacturer smell? It's been going for a few weeks sometimes 5-10 hours at a time and still a lot of oily or chemical smell.
By Collin C. - NFI Master Hearth Professional on January 23, 2013

Answer:
Usually, most of the manufacturing oil burn off and paint curing will be completed by the first 10-12 hours of burn time. If the unit was produced very recently, the cure time can be a bit longer. If the smell persists, I would recommend checking the door seal to be sure it is fully seated, as the unit may be leaking combustion gases into the room if the door is not seated properly.

By Dee from Raleigh, NC on February 11, 2013
Do you sell gas propane un-vented gas logs with a thermostat and a blower fan? I need 33" or a tad larger logs. We've really needed a set that has an automatic fan.
By Tyler M. - Fireplace Specialist on February 12, 2013

Answer:
While we do carry a variety of ventless propane gas logs, none of them have a blower option. You can see our full selection of ventless log sets below:

For a see-thru gas fireplace, what is the best way to arrange the logs?
By Collin C. - NFI Master Hearth Professional on March 25, 2013

Answer:
While it depends on the particular log set that you have, it is typical for the log set to have a pair of main bottom logs. The logs are positioned at the front of each side of the log grate. Various other logs are usually provided to lay back and forth across the main logs. Ideally, the logs would be placed to cause as little disruption to the flame as possible, as this will cut down on the amount of sooting that you will experience from the log assembly.

By John from Sedgwick, Maine on January 23, 2013
I have a vented fireplace with a 12" flue. It is a Rumford style - width of opening is 33", height of opening is 30", depth @ floor level is 14", width @ back is 14", sidewalls are 14" on a 45 degree angle to the back. Currently burning 12" to 14" wood, but would like to convert to propane gas logs, what can you suggest?
By Tyler M. - Fireplace Specialist on January 24, 2013

Answer:
Depending on the width of your fireplace in the middle, halfway back from the front, you may be able to fit this log set:

Real Fyre 18" American Oak Vented Propane Gas Logs Set with Safety Pilot Kit

This log set requires 24" of middle width. If you have enough room, this would be a nice vented log set for you. This same log set/burner offers the ability to add a remote-ready pilot kit that can utilize an optional remote control or wall switch. You can see one such example here:

By Dennis Hickman from Kingsport, TN on December 29, 2012
I have an old coal burning fireplace, and it's very shallow (approximately six inches.) I want to convert it to a gas log set, but I'm having trouble finding a set small enough. Is anything made for these small fireplaces?
By Collin C. - NFI Master Hearth Professional on December 31, 2012

Answer:
While we do offer several reduced depth coal and log baskets that are meant for coal burning fireplaces, the fireplace opening must be at least 9 inches deep to accommodate them. A depth of 6 inches is very shallow, even for a coal burning fireplace.

By Jan Willoughby from Cave Creek, AZ on December 29, 2012
I have a wood-burning fireplace that I no longer use. I would like to put in a propane setup with propane outside on patio. My current fireplace is about 36 inches wide by 25 deep. I believe the back width is about 23 inches.
By Collin C. - NFI Master Hearth Professional on December 31, 2012

Answer:
Based on your dimensions, a 20-inch outdoor log set could be used in your fireplace. One popular set is the Real Fyre 20" Post Oak Outdoor Propane Gas Logs Set with Safety Pilot Kit. The log grate and burner assembly is manufactured from durable stainless steel, which will hold up to the elements.

We also offer several other 18- and 20-inch log sets that can work in your opening, should you wish to use a different style. Our complete selection of outdoor logs can be seen here.

I have a prefab Heatilator fireplace that has an outside draw with glass doors. The fans are noisy with a gas lighter. What type of gas logs would you recommend as a replacement for the best heating results?
By Tyler M. - Fireplace Specialist on January 15, 2013

Answer:
For best heating results, we recommend a
ventless gas log set. You would close the damper on your Heatilator and all the heat stays in the room. If you reply with the dimensions of your fireplace (front width, rear width, depth) as well as your fuel type (natural gas or propane), we can make some recommendations.

By AP from Richmond, VA on November 2, 2012
I have been looking for vent-free BIRCH logs that use natural gas but can't find them. Are they available?
By Tyler M. - Fireplace Specialist on November 2, 2012

Answer:
The only birch logs we sell are vented, not ventless. We apologize for this inconvenience.

How do I protect my mantel from the heat rising from the fireplace?
By Collin C. - NFI Master Hearth Professional on December 31, 2012

Answer:
The best way to protect a wooden mantel is by using a fireplace hood. We have several sizes and styles of hoods that can mount according to your needs.

Answer:
Because the burner pan lays flat upon the fireplace floor, I do not recommend running the gas line in this way, unless the line is against the back wall of the fireplace and out of the way.

I have a Martin Industries gas log heater AU40L/U40T/UF40T, installed around 1997 and has worked wonderfully until recently. Now it emits a gas odor when in use. What's the average life span of these heaters?
By Collin C. - NFI Master Hearth Professional on February 13, 2013

Answer:
Typically, unvented fireplaces and decorative logs will last approximately 20 years when serviced regularly. Buildup of debris in the main burner orifice, dust or debris clogging the air shutter, and perforation of the main burner tube can all cause issues with odors and CO emission. I highly recommend having the unit inspected and serviced if necessary. If any corrosion or damage to the burner is present, the unit will likely need replacement.

What is the difference between vented and ventless?
By Magan B. on December 31, 2012

Answer:
The basic principle separating the two types of gas logs is that vented gas logs require some means of venting the combustion by-products and exhaust resulting from the burning of any kind of fuel, and ventless or vent-free gas logs do not.

In practical terms, this means that lots of things (including some heat) go up the chimney or out the vent pipe when using vented gas logs, and almost everything (especially heat) is contained in the home when dealing with vent-free logs.

What is a setback or buffer that is referred to when seperating the firebox from the mantle?
By Collin C. - NFI Master Hearth Professional on January 16, 2013

Answer:
Fireboxes require a clearance from the edges of surrounding mantel legs and shelf. Clearances from the surrounding combustible material and how far the material can project from the wall will depend on how far back the firebox is set into the wall. Additional clearances must be observed when installing the unit into a cabinet mantel. It is common to require 3/4 to 1 inch of space for this type of installation.

We have a gas (propane) fireplace that is see-thru between our kitchen and living room. When you turn it on, it burns for a little while then starts to go out on the end away from the pilot, then the middle goes out till there is only a third of the burner working. We have had the regulator checked and that is not the problem. Any suggestions?

We have been thinking about getting it replaced with one that has a battery backup for if the electricity goes out, but we don't really know where to start and would like to repair the old one if it is cheep enough to do so.
By Collin C. - NFI Master Hearth Professional on December 10, 2012

Answer:
Per your description, it sounds as if something is causing gas pressure to the main burner to slowly reduce. This could be caused by debris clogging the main burner orifice, low millivoltage from the pilot assembly, or a defect in the valve itself.

When the regulator was checked, was the gas line and orifice checked for debris? Do you notice any change in the pilot light flame size? Can you hear any odd noises coming from the gas line or gas valve?

What kind of an energy top damper can I use for gas logs?
By Tyler M. - Fireplace Specialist on February 14, 2013

Answer:
The manufacturer for our chimney top dampers explicitly warns against using them with gas logs. This is because a failure to open could cause carbon monoxide to back up into the house. Moreover, in the case of a gas leak, gas could be trapped in the flue, resulting in an explosion.

Can you convert natural gas logs to propane?
By Kevin E. - Fireplace Specialist on January 16, 2013

Answer:
Indeed, most vented gas logs can be converted from one gas type to another. The required conversion pieces vary with manufacturer and log set size. Vent-free log sets, on the other hand, cannot be converted.

By Linda from Beaumont, Texas on January 16, 2013
I have a natural gas fireplace. I live in SE Texas and don't need to use it as a source of heat for my home. So, with that in mind am I understanding that the "vent" type is best for me? Is this something I can do, are there any special procedures to disconnect the existing gas pipe and connect the one for the gas logs?
By Tyler M. - Fireplace Specialist on January 16, 2013

Answer:
Yes, we would recommend a vented gas log set for the most authentic flames for your application. We do currently have our Real Fyre log sets on sale; please see a couple of our most popular 24" log sets below:

I now have a wood burning fireplace that has not been used. I am considering putting in gas logs. I want the real look, but also want efficiency.

I have heard that vent-free logs can produce a kerosene smell. Do the vented logs also produce gas smells? I am very sensitive to smells and don't want to spend a bunch of money and not be able to use the fireplace.
By Collin C. - NFI Master Hearth Professional on November 26, 2012

Answer:
Vented gas logs do not produce a detectable smell; however, they will only offer supplemental heat to the immediate area around the fireplace and are primarily decorative. While high quality vent free log sets produce less of an odor than most sets, individuals with a strong sense of smell will indeed be able to pick up the burnt gas residue in the air. If you are able to detect the smell of a gas range or oven burning, you will likely be able to smell gas logs.

Another option you may not have considered would be a direct vent fireplace insert. These units are completely sealed from the room, drawing combustion air and venting exhaust from the chimney termination. These units offer much greater efficiency when compared to vented logs, but do not have the negative drawbacks to vent free logs.

A good example of this type of unit is the Innsbrook Medium Direct Vent Gas Fireplace Insert. While this type of unit is more costly, its efficiency makes it worth the expense in the long run and can allow you to use the fireplace as a genuine source of heat.

I have a gas fireplace and I need the logs that go inside. Do the logs really make a difference or is it just for looks?

By Chris on January 7, 2013

Answer:
A log set by R.H Peterson will make a difference as the logs themselves are constructed from refractory cement. As the fire is burning the logs will absorb heat to help radiate the heat into the living space while the fire is burning, as well as continue to radiate heat into the living space once the flame is extinguished.

My fireplace is 36" at the front, 30" across the back, 26" deep and 26" tall. What size log set should I buy?
By Kevin E. - Fireplace Specialist on February 14, 2013

Answer:
Proper log sizing would depend upon your control preference and gas type. Per your dimensions, you could safely install an 18" or 20" log set with remote control in either natural gas or propane. Or, you could opt for a match light 24" log set in natural gas. Propane does not afford the option for a match light unit.

I have a gas log that was installed in my living room when I bought this circa 1926 house. When we use the gas log, it sends soot all the way up the front of the mantel and up onto the ceiling!

I've had the chimney guy out, and he said he thinks its vented and that I should replace it with a ventless log. Do you have any thoughts?
By Collin C. - NFI Master Hearth Professional on October 29, 2012

Answer:
While vented logs can indeed produce soot, they should vent any byproducts into the chimney rather than putting the material into the room. Is the chimney itself in good working order and the damper open when the set is in use?

It would certainly be an option to switch to vent-free logs, as they produce very little byproduct while burning. However, the chimney must still be intact and operable for vent-free logs to be used, as some heat will still escape up the flue.

We have gas logs without a blower. Can a blower be added if not equipped for one?
By Collin C. - NFI Master Hearth Professional on January 28, 2013

Answer:
In most cases, a blower cannot be added to gas logs by themselves. Where the logs installed into a masonry or manufactured fireplace? If they are installed into a manufactured box, does it have louvers on the face? What is the manufacturer name and model number of the box? Please advise at your convenience.

We have a prefab wood burning fireplace which is now closed off with the chimney removed. We would like to purchase vent-free gas logs but don't know if our present firebox can still be used. Can vent-free gas logs be used with our present firebox, or should we purchase a vent-free firebox to be used with vent-free gas logs?
By Collin C. - NFI Master Hearth Professional on December 3, 2012

Answer:
Because the chimney has been removed, it will be more cost-effective to replace the existing prefab box with a vent-free firebox. In order for you to use the existing fireplace, the chimney would still need to be intact and in good working order.

By Clark from Sun Prairie, WI on April 17, 2013
I am looking for a blower system that will work with my standard gas logs, that would take the heat from under the logs and bring it up the back then over top of my logs and out into the room. What would work?
By Chris on April 17, 2013

Answer:
We currently offer two products that may work for your application. Please see both the Stoll 20 in. W x 17 in. D Grate Heater as well as the Stoll 24 in. W x 20 in. D Grate Heater.

By Larry from Johnson City, TX on January 8, 2013
I have a wood stove and want to convert it to propane logs. It is lined with fire brick and is only 22" wide and 14" deep (front to back). The front door opening is 19" wide and 12"high. I already have a propane line into the firebox, but am not sure if a pilot system would work in this case. I can manually start it if need be.
By Collin C. - NFI Master Hearth Professional on January 8, 2013

Answer:
For propane, a gas valve with standing pilot is almost always needed, due to the volatility of the fuel. All of the LP sets that we carry come with a valve and cannot be ordered as a match light version. My fear with using the stove is that the valve will overheat and fail. Would it be possible for you to locate the valve outside the stove body? Please advise.

What would be the best option for a replacement log for a Martin industries model AVFG30/VFG30?
By Collin C. - NFI Master Hearth Professional on May 13, 2013

Answer:
Per the manufacturer, original stock of the log set for this unit is no longer offered and unfortunately, there is not a direct replacement that is made. Due to issues with sooting and overheating, they do not recommend trying to retrofit another log set to this unit. In this case, it would be necessary to try former Martin dealers to see if they still have stock of the original log sets.

Not sure what the differences are between vented gas logs and vent free gas logs?  Here is a brief explanation of what to consider when purchasing gas logs for your fireplace.

  • Vented Gas Logs – Vented gas logs are to be used with an open chimney flue or damper.  The decorative fire they produce is large and realistic, but does not work as a very efficient heating source, as most of the heat escapes through the chimney.  To produce this realistic flame, the logs also use more gas. 
  • Vent Free Gas Logs – Ventless gas logs do not require a vent, like a chimney, to operate.  This means that most of the heat generated stays in your home, and may actually save you money on your heating bill.  They’re also a much better choice for the environment, because the harmful by products are not released into the atmosphere.  Some even have a thermostat to control the temperature.  However, the fire does not look as real as a vented gas log, and they add moisture to the air.  This can cause mildew if the proper precautions are not taken.  Another major concern is that these logs use oxygen to burn cleanly, and if they are burned for too long without introducing clean air into the room they can pose a danger.  It’s crucial to install a carbon monoxide detector into any room using vent free gas logs.
