- Electronic Remote Pilot – (Vented & Vent Free) This control type will include a remote and have a non-standing pilot that will ignite when activated by the remote, allowing gas flow to the main burner. With vented sets, the flame height will be fixed. With ventless sets, the remote will also allow you to adjust flame height.
- No Pilot – Match light – (Vented Only) This will not feature a valve and will only be available with vented natural gas log sets. This option is not available with any ventless log set or any propane set. The burner will be lit with a match and the gas flow/flame height will be controlled with a previously installed manual ball or gas valve in the fireplace. Typically, this valve is located outside of the fireplace opening on the floor or wall.
- On/Off Remote Pilot – (Vented & Vent Free) This pilot kit will feature a standing pilot that will have to be lit manually. The optional wall switch, On/Off or On/Off thermostatic remote will ignite the burner only. The flame height may be adjusted manually with the valve control knob, but not with the optional remote.
- Safety Pilot – (Vented & Vent Free) This is the most basic safety valve available for vented propane log sets but is also available with vented natural gas log sets. The pilot is lit manually using either a match or long stem butane lighter via the valve control knob. After a few seconds, the pilot flame contact with the thermocouple will allow gas flow to the main burner. If the pilot flame is extinguished for any reason, gas flow to the main burner will cease, preventing the open flow of gas into your home (this will be the case with any pilot kit, with the exception of the natural gas match lit option).
- Variable Flame Remote Pilot – (Vented & Vent Free) With vented log sets, this pilot kit will feature a standing pilot that will have to be lit manually. The optional Variable Wall Switch will turn on the flame and adjust the height up and down. The optional Basic Variable Remote will turn the unit on and off as well as adjust the flame height up and down, while the Deluxe Variable Remote will add thermostatic control. With ventless log sets, your results may show both standing and non-standing pilot kits. Either option will include a remote, but only the “Variable Flame Intermittent Pilot” option will feature a non-standing pilot flame that may be lit with the remote. You will be able to select either option on the left-hand side of the page in your filtered results.

What is the difference between G45 and G46 burners? It appears that the G45 requires a larger opening when comparing the same sizes. A G45-24 shows a requirement of 34" while a G46-24 shows 30" required. I'm looking at series 11 control
1 Answer
Yes, these burners are very similar, but the G46 is designed at a much steeper taper towards the rear of the firebox to be able to fit the control valves in tighter fireplace openings.

from Madison, MS asked:
April 11, 2023
Which gas log puts out more heat, vented or ventless?
1 Answer
This answer is two-fold; vented gas log sets typically produce more actual heat (higher BTU ratings), but ventless gas log sets are designed for applications where the heat generated can be retained. Vented gas logs require a functional woodburning chimney, and the damper must remain fully open when in use, whereas ventless gas log sets can be operated with the damper closed, keeping the heat in the room.  For more information, please see our gas log buying guide here.

Wes
from NY asked:
December 2, 2022
Which burns hotter: vented or non vented?
1 Answer
Typically, a vented gas log set will have a higher BTU rating for better flames and more heat produced, but the vast majority of that heat will escape up the flue. A ventless set will have a lower BTU rating but of course, you can close your damper and almost all of that heat is retained in the room, making it a great option for supplemental heat. Please consult local codes as to whether or not a ventless set is permitted in your area.

from Texas asked:
December 12, 2021
How do you know if you need ventless or vented?
1 Answer
The main concerns are your existing fireplace, and what you're looking for in a log set. The chimney of your fireplace needs to be in full working order for a vented gas log set. Vented sets are going to give you a larger flame, but you will lost a majority of the heat through the chimney. Vent free sets will have a smaller flame, but will produce a great deal of heat, so you would want to choose based on your desire for heating or aesthetics. Â

Is there a problem with using vent free logs in a vented fireplace?

This depends on the nature of the unit. If it is a brick/masonry woodburning fireplace or a manufactured woodburning fireplace that is listed to accept a ventless gas appliance, there is no issue. You cannot, however, install a ventless gas log set inside a vented gas fireplace.

Whats the difference between vented and unvented gas logs?
1 Answer
While vented sets require the flue to remain open at all times, ventless units operate at a high enough efficiency to put out water vapor and carbon monoxide during combustion, so it can vent right into the room. Vented sets will have a larger flame, but vent free sets will give you a great deal more heat.Â

I have a fireplace with a gas line that we use to light our wood fires. Is it possible to fit our fireplace with gas logs that can be easily removed if I want to burn wood?

While it is certainly possible to install a vented gas log set, it would not be easily removable, as you would have to disconnect a gas line each time, then cap it or re-connect it to the log lighter before burning wood.

The fireplace I have now was always a propane gas fireplace. It is also open on both sides. I would like a vent-free propane gas log set that would accommodate my two-sided opening fireplace. Is there such a log set?
1 Answer
Ventless gas log sets may only be installed in one of two applications; a fully functional masonry wood-burning fireplace that's been outfitted with a gas connection or a tested and listed ventless gas firebox. A gas fireplace differs from both in that gas fireplaces are made with gas controls preinstalled outside of the visible opening, typically in a hidden control cavity just below the decorative logs. If you have a gas fireplace, installing a ventless gas log set will not be an option. Please review this article describing where the make, model and serial number is commonly located on both gas and wood fireplaces, in addition to gas log sets to determine the type of appliance you currently have. Please reply with this information along with photos as we are able to identify the appliance type with multiple clear photos of the hearth.

What causes the logs in a vent-free propane fireplace to break and crumble? I have bought 3 sets by 3 different manufacturers in big box stores, and for the last 10 years and they have all done the same thing! What can I do to prevent this?
1 Answer
Log sets purchased at the big box stores you'd mentioned will typically include decorative logs made of ceramic fiber, which is a lightweight, semi-porous material that will most certainly break down over time. I recommend choosing a log set including solid refractory logs as the logs themselves will last a lifetime and will not crumble over time. For example, any ventless log sets produced by Real Fyre will include refractory logs backed by a lifetime warranty.

How do I determine whether my gas fireplace is vented or ventless ?
1 Answer
A ventless gas fireplace will have doors that can be easily opened or no doors at all. A vented fireplace will have a sealed combustion chamber, which means a glass front that requires unlatching some clamps or screws to open the area where the logs are located. There should be a data plate on your fireplace that will specify if the fireplace is vented or ventless.

If you are only considering the G10 burner, any of the G10 log sized would work and so you could actually install a larger 30". For aesthetics, I'd probably stay with the same 24" log size.

Gas logs are a wonderful solution for converting an existing masonry fireplace into an aesthetically pleasing and easy to use focal point in any room. They are also called fire logs, fake fireplace logs, and even gas fire logs and we have a wide selection. Finding the right gas logs for fireplace doesn't have to be a headache any longer. Have you been looking at direct vent or vent free complete fireplaces but don't like the gas fireplace logs they come with? A gas firebox with a separately purchased gas log set may be the solution. Unlike the handful of options offered with complete systems, you can choose from hundreds of gas log sets to match into a gas firebox, giving you just what you are looking for.
Both vented and vent free fireplace gas logs are available, with different advantages and disadvantages to each. The size of the room, size of the fireplace, and what you expect to get from them in terms of performance all make a difference into what you will ultimately need. To ensure you are completely satisfied with your fireplace logs, we offer an in depth buyer's guide that gives a thorough look at these products. Learn more about gas fireplace logs by reading our Gas Logs Buyers Guide.
