Vented Gas Logs

Vented gas logs provide a high, realistic-looking flame in your hearth that is a great alternative to a woodburning fireplace. Vented gas logs are extremely popular, so there are not only tons of styles offered, but there are also all sorts of venting options available. Our vented gas log offerings represent all of the best manufacturers and gas log styles - a vented gas log solution for every home.

Do you install the gas logs?
By Collin C. - NFI Master Hearth Professional on November 9, 2012

Answer:
We are in sales only of our products. The gas log assembly would need to be installed by a local plumber or HVAC technician.

I would like to replace my log set. I seem to have carbon build up.How do I prevent this problem ?
By Tyler M. - Fireplace Specialist on January 29, 2013

Answer:
Issues with incomplete combustion are usually the result of irregular log placement on the burner assembly, resulting in flame impingement (contact) with the logs. If the logs are installed according to the manufacturer's instructions, this can be avoided. The only replacement logs we sell are the R.H. Peterson Real Fyre brand, only for use on the Real Fyre burners.

Our direct vent fireplace produces very little heat. Our house is only seven years old. I added the blower option and it helped a little but still not much increase in warmth. Any suggestions? Our great room has vaulted ceilings and measures 15 x 20. We're using a Heatilator model # ND4236.
By Collin C. - NFI Master Hearth Professional on October 22, 2012

Answer:
While we are not a dealer of Heatilator products, specifications I have found for this unit indicate that it is a 25,000 BTU unit with 73 percent efficiency. This would equate to 18,250 BTUs of heat being felt in the room, which is a lower midrange output for direct vent appliances.

Some direct vent units offer the use of a restrictor disk, which is designed to keep the firebox warmer and boost output. However, I was not able to find mention of one in the manual for this unit.

Unfortunately, this is the only option that is commonly offered, other than the blower, to help thermal efficiency. My only other suggestion would be to verify that the flame control knob is adjusted to the "High" position and that there is proper gas pressure being supplied to the unit. Misadjustment of the flame control or insufficient gas pressure can cause a lower flame and less heat output.

I have a 960 sq foot condo with a vented gas log that doesn't heat. We are at 7800 elevation so I don't think a ventless insert would be recommended. What do you recommend as we are in snow country? I have a zero clearance wood burning fireplace insert in another home that does have a gas starter. We are at sea level and I wanted to see what options we might have to convert to gas?
By Tyler M. - NFI Certified Specialist on March 19, 2013

Answer:
For the condo at high elevation, we recommend a direct vent gas fireplace insert. You can see our full selection here:

Direct Vent Fireplace Inserts

These inserts can be installed inside a brick/masonry fireplace or a manufactured fireplace. Please double-check dimensions to ensure any particular model will fit and work for you. Please also note that these require venting (co-linear aluminum liners), so you will need at least a 7" diameter existing chimney in which to house the appropriate vent kit.

As for the house a sea level, you will also need a direct vent gas insert in that application, as vent-free gas appliances are illegal in California. Direct vent inserts are very efficient (some models more so than others), and will provide a good secondary heating source for these homes.

What is the difference between vented and ventless logs?
By Tyler M. - Fireplace Specialist on October 30, 2012

Answer:
There are a few primary differences between vented and ventless logs. First, the vented logs will need to utilize an existing, functioning chimney. Ventless logs can be used with no chimney at all; you simply close the damper in the fireplace where you have installed the logs. Vented logs produce more overall heat, but a great amount of this heat will go up the chimney.

Since ventless logs do not use a chimney, almost all of the heat stays in the room. Please also note that vented gas log sets also provide a more realistic flame.

For more information on differences and pros and cons, please see a brief explanation at the bottom of this page.

How do I get more heat into the room from my gas fireplace? It looks nice but most of the heat goes up the chimney.
By Collin C. - NFI Master Hearth Professional on January 14, 2013

Answer:
Your options will depend on the type of setup that you have installed. Is this a masonry or manufactured fireplace that had vented gas logs installed into it or did the unit come as a package with the logs and burner as part of the assembly? If it is a manufactured box, do you have the manufacturer name and model number of the unit? Please advise at your convenience.

By Don from Lancaster, NY on November 19, 2012
I have a gas burning insert now and wish to replace it but I'm not sure about the venting. We don't have a chimney but we do have a vent that goes to the outside from the fireplace. Is this considered vented even though it does not have a chimney? If so, what would you recommend?
By Tyler M. - Fireplace Specialist on November 20, 2012

Answer:
Yes, this would be considered "vented," and it sounds like you have a direct vent fireplace. If this is the case, you cannot simply replace the log set inside; you would need to replace the entire system (firebox, burner, logs.)

Depending on the manufacturer and model information, you may be able to utilize your existing pipe with a new model. If you cannot use the pipe, we do offer vent kits for all of our direct vent models.

When you say "match light," are you lighting a pilot which then stays on? Should the pilot go out, will the gas valve close?
By Collin C. - NFI Master Hearth Professional on December 17, 2012

Answer:
Match light gas log sets will not have a pilot assembly. Rather, you would need to use a lighter or long match to manually light the log burner after opening the gas valve. In order to extinguish the flames, you would simply close the gas valve completely.

Where do you find a professional to provide installation?
By Tyler M. - Fireplace Specialist on October 23, 2012

Answer:
For gas logs, a local plumber should be able to do the installation. We recommend calling around and quoting the job to a few different plumbers.

By Donald from Massapequa, NY on March 23, 2013
The dimensions on my woodburning fireplace is 41" wide (front), 28" wide (rear), 22" (depth) and 31" (high) with natural gas. Which is the best size - 24 or 30? Which logs will be the most realistic?
By Collin C. - NFI Master Hearth Professional on March 25, 2013

Answer:
We offer the Real Fyre line of logs, manufactured by R.H. Peterson. These sets are among the most realistic in the industry, featuring highly detailed ceramic refractory logs and an advanced burner system with your choice of control valve. The recommended size of the log set will depend on the gas valve.

By Marlene from Lawrenceville, NJ on December 29, 2012
We are interested in converting our prefab wood fireplace into a gas log system. Our firebox is 30" at the front and 20" at the back. The depth is 15".

When I put the dimensions into your converter, it brought up two 12" see-through systems. We do not need a see through, and would like 18" logs if they would fit properly. What would you recommend?
By Collin C. - NFI Master Hearth Professional on December 31, 2012

Answer:
I apologize for the confusion on the gas log calculator. If you are using natural gas, you could use either an 18-inch or 20-inch match light set. You could also fit an 18-inch set with a manual safety pilot kit, which is a standing pilot valve that has a rotary control to turn the unit on and off.

If you are using propane, you could only select from the safety pilot kit, as Peterson does not offer propane kits in a match light configuration for safety reasons.

I would like to replace the logs in my Regency U39 fireplace. Which set should I use? Can I use the lava or ember kit?
By Collin C. - NFI Master Hearth Professional on March 8, 2013

Answer:
Upon researching this unit, it appears that it is a free standing direct vent stove. Because of potential sooting and overheating issues, these units must use the original type of ceramic logs that they come with. The cast refractory logs that we carry cannot be used in a sealed appliance.

My recommendation is to check with a local Regency dealer for availability of the original logs or another ceramic set that is listed for use with this appliance. I apologize that we do not carry the needed items.

By Robert from El Paso, TX on October 24, 2012
Are any of the gas logs thermostat controlled?
By Tyler M. - Fireplace Specialist on October 24, 2012

Answer:
Yes, all of our Peterson RealFyre vented gas log sets have the option to add an on/off remote pilot kit or a variable flame remote pilot kit. Either of these pilot kits allow for the use of a thermostatic hand-held remote control, where you can set a temperature and the log set will operate accordingly.

We have 2 see through fireplaces 42", 2 regular fireplaces 36" and 1 regular fireplace 42" what are the correct size inserts for these fireplaces?
By Tyler M. - Fireplace Specialist on January 24, 2013

Answer:
Are the widths on each of your fireplaces the same in the front as in the back? This is almost always the case for a see-through fireplace, and you can install a 30" see-thru gas log set if your see-through unit has 42" of width all the way to each opening. However, please reply to confirm the depth of each of your fireplaces, as well as the rear widths of your standard, one-sided units. Moreover, please let us know if you would prefer to operate the gas log sets with a remote control or wall switch, and if you are interested in a variable flame option. Finally, please advise if you will be using natural gas or propane, and if you prefer vented or ventless log sets. With this information, we can make recommendations for each of your fireplaces.

By Susan from Chapel Hill, NC on November 3, 2012
We have a Tempco TFS36-3 fireplace that we been burning wood in for the past few years. We are ready to convert to gas. We mainly use the fireplace for the look and not for heat. Should we be using ventless with this unit?
By Collin C. - NFI Master Hearth Professional on November 5, 2012

Answer:
After locating an owner's manual for this particular unit, it does not advise that vent free logs are acceptable for use in this unit. However, it is certainly feasible to install a set of vented gas logs, as the unit is equipped to deal with this sort of heater. This would be in line with your needs, as vented gas logs offer a large flame and look great, but do not add much supplemental heat.

Depending on the pilot type you select (manual control, remote, match light, etc.) you would be able to use either an 18" or 24" set.

By Karen on November 9, 2012
I have an Empire Comfort Systems vented fireplace with a remote. The model number is VFSV-18C-1. I need to replace the log set. Can you advise me which log set that I should order?
on November 9, 2012

Answer:
Upon researching the information you provided, this model number is for the log set only which is no longer manufactured. In order to replace the existing set, you would need to purchase a complete new log set and burner system. The firebox itself will have a different model number from the logs, and can be used with any vent-free log assembly, provided that the replacement burner dimensions match your firebox. For safety reasons, manufacturers do not offer replacement vent-free burners and log sets separately. We would be happy to guide you in choosing a new log set and burner assembly if you can provide us with your firebox dimensions. Please let us know if you have any additional questions.

By Mike on November 9, 2012
I had my gas log set inspected and was told to have it replaced. The pilot unit was also corroded and should be replaced as well. What is the best way to approach this? This is somewhat confusing.
on November 9, 2012

Answer:
We would be happy to help you find a replacement gas log set. You can see our full selection here: Gas Logs To further assist you, please reply with the dimensions of your fireplace, including front width, rear width and depth. Also, please let us know what kind of fuel you use (natural gas or propane) and what type of pilot kit you would like - manual safety, automatic on/off, variable flame, or electronic. With this information, we may be able to suggest a few log sets for you. We look forward to your response.

I want to convert a wood burning fireplace with a gas starter to gas logs. Because it is a wood burning fireplace, it has a flue. Do I have the choice of vented or unvented logs?
By Collin C. - NFI Master Hearth Professional on November 26, 2012

Answer:
If your fireplace's flue is in good working order, it is indeed possible to use either a vented or vent free log set. Vented logs will offer a more realistic appearance, but are largely for aesthetics. Vent free logs are very efficient and will add much supplemental heat, but have a low flame and can irritate individuals that have a keen sense of smell.

I have a round, outdoor wood burning firepit and have installed a propane gas igniter to start its fire. I would like to use ceramic logs instead of wood, as the pit is on our covered deck and we often end up with smoke in our faces when the wind changes. My firepit is 24 inches in diameter and 10 inches deep. The propane ignitor is 10 inches long and 2 inches wide and 2 inches deep. It is a bar with holes in it. Can you advise me how to replace the wood logs with ceramic logs?
on November 9, 2012

Answer:
We offer a couple of styles of refractory logs that can be used to retrofit your existing wood burning firepit. Please follow the below links to check out our current options. Replacement 24" Burner Assembly: PTS-OCBE-44P Log Assembly for representation purposes. The logs shown by following the second link can be had free of the firepit assembly shown. For these, we'd have to enter a special order for you. It is also possible to use a stainless steel grate, such as the following item: stainless steel grate The grate could be used in conjunction with a Peterson log set of your choosing. Because the logs are not designed to be used with a standard grate, you may have to get a bit creative with their placement, but it can be done. Any of our Peterson log sets by themselves will work. Please view the following link for styles available: Gas Logs w/o burners. A standard 18" or 24" could work perfectly for your requirements.

My gas line feeds in from the left, but the burner’s pipe opening is on the right. What steps do I need to take?
on November 9, 2012

Answer:
You may find a gas flex line to connect the gas line to your burner assembly. We have many different lengths of flexible gas line to connect the pipe to your burner.

I am hiring a contractor to repair my chimney. He will take care of the deterioration of the outside; however, the interior is equally as dangerous. He has recommended that I consider installing a propane burning gas log unit. In doing my preliminary research on your website, I am concluding that I would need to replace the existing wood burning box with an insert. Also based on my situation, would I need a vented or vent-free unit?
on November 9, 2012

Answer:
If the fireplace is being removed, you could easily go back with a complete zero clearance vent-free fireplace. This item would be the complete package. It would replace the entire fireplace and come equipped with the burner assembly and log set. Of course, being vent-free it would require no venting. However, if the fireplace is remaining and only the chimney is being removed, you do indeed have the option of installing either a just a log set or installing an insert. In either case, if the chimney is being removed, a vent-free appliance would be the way to go. If the interior of the fireplace is indeed in bad shape, it may be better to go with the insert. A vent-free insert will completely renovate your appliance, while a log set will simply dress up your fireplace's interior.

By Joe on November 9, 2012
I have a regular fireplace in my house that I would like to convert to gas. I have a natural gas line directly underneath the fireplace in the basement next to the boiler. Is it possible to run a gas line up into the fireplace and connect it to a burner that looks like logs? I would also like a remote if possible. Can I use the existing chimney, or should I adapt it somehow?
on November 9, 2012

Answer:
The application you describe is one that is perfectly suitable to our gas log sets. Any of our units by R. H. Peterson would suit you well. These units can be controlled manually (match lit), with a safety pilot kit, or with a remote controlled valve. Control option and size of log set are directly related to the size of your fireplace. If your chimney and damper are in good working order, no adaptation is required.
