Correctly sizing your Gas Logs for your Fireplace is VERY IMPORTANT!
CLEARANCE IS CRITICAL!
Every type gas log burner system must remain a certain distance from the side walls of the fireplace in order to stay cool, which is referred to as "Clearance" (see Fig.3 below) . The amount of clearance varies depending
on the type of gas log burner and controls you select. When the clearance is not met, the gas valve can overheat and melt, which will cause your log set to stop working...and can also create an unsafe condition.
Although you might think that the biggest logs that will fit into your fireplace will look the best, you must also consider how much space must be left on each side of the burner system in order for it to be safe.
Over-sizing of gas logs is the #1 cause of failure with gas logs. Follow these instructions carefully to avoid making a costly mistake!
Measure the: Front Width x Back Width x Depth
Fig.1 Masonry Fireplace
This example shows a masonry fireplace with a marble front that is flush with the firebrick on the inside, so the Front Width measurement is the same as the actual fireplace opening.
Fig.2 Metal Prefabricated Fireplace
Here's a prefabricated fireplace where the width between the fireplace walls is less than the fireplace opening, so the Front Width measurement is smaller than the fireplace opening.
FRONT WIDTH: The front width is the actual "usable" space between the side walls inside your fireplace at the front, not necessarily the width of the opening. If the facia around your fireplace opening is even with the side walls of the fireplace on the inside, then the Front Width measurement is the same as the fireplace opening (see Fig.1). If you have a prefabricated metal fireplace (zero clearance fireplace) where the opening is actually wider than the width between the side walls inside, do not base the front width on the size of the opening, measure the functional width between the side walls of the fireplace (see Fig.2).
BACK WIDTH: The Back Width is pretty self explainitory and is the measurement of the narrowest width in the back of the fireplace (see Fig.1 and Fig.2 ).
DEPTH: The Depth is simply the measurement from the front to back of your fireplace on the inside. The Front is at the point from which you took the Front Width measurement (see Fig.1 and Fig.2 ).
Height: The height of your fireplace opening needs to be at least 18" for most gas logs. This may vary somewhat between models, but if your opening is at least 18" tall, you will not normally need to be concerned about the height of your fireplace opening..
About the Center Width: Use this measurement to confirm our calculations! The Center Width is the inside width measurement taken 7" back from the point from which you measured the Front Width. The "Center Width" is not a measurment that you enter into our Gas Log Size Calculator, it is automatically calculated based on the Front and Back Width dimensions that you enter into our calculator. This is approximately where the burner and pilot will be positioned when your logs are installed, which is the point where the clearances are critical. This is the most accurate way of determining if a particular gas log will work in your fireplace and no other website performs these calculations for you. So when you see reference to the required "Center Width" for our gas logs, you will know what this is referring to (see Fig.3). Compare this measurement to our calculations before making your purchase to ensure the logs you order will fit!
Enter your measurments into our calculator to find the right size logs for your fireplace. Our calculator automatically allows
for the "Proper Clearance" based on the type of controls you select. Results are sorted by the "Largest Logs" that will fit your fireplace while maintaining the required clearance.
(*) The Asterisk shows where clearance from a safety pilot is required and calculated
Fig. #3 above shows how the clearance from each type of gas log burner or control is required from the side walls of the fireplace. The critical measurement is the center width of the fireplace where the burner is placed. Our calculator automatically calculates this distance and takes into account the required clearance for every gas log burner system that we offer. When you use our calculator, only logs that will fit your fireplace will show up in our search results.

What are the different control options for Gas Logs?
Important Note: Liquid Propane always requires a
safety pilot, whereas Natural Gas does not.
Match Light (no pilot): Match
light systems do not have any type of safety pilot. You start the fire by
lighting a long lighter or match and holding it inside the fireplace just above
the burner while you turn on the gas. The gas valve should be located either in
the wall or floor. If your gas valve is inside the fireplace, be sure that it is
legally installed. Most cities require that you at least have a cut off valve
outside the fireplace that is in reach. Match light burners are substantially
less expensive than other options, but are not legal in many cities.
Manual Pilot: Manually controlled gas logs have
a safety pilot that stays lit all of the time (it can be turned off during the
off-season). The safety pilot attached to the burner will have a knob that you
turn to light the fire manually. This knob works as long as the safety pilot is lit. You
cannot use a remote control with a manual safety pilot. Manual safety pilots are
less expensive than remote control pilots because they use a less sophisticated
system. This is also the least expensive way to operate gas logs with Liquid
Basic On/Off Remote*: A remote capable safety pilot
has the capability of being controlled by a hand held remote control transmitter
or by a wall switch. Both the transmitter and receiver are battery operated,
so they do not have to be hard wired. The wall switch option (sold separately) includes a small
millovolt wire that goes from the wall switch to the pilot valve, but is not hard wired
to your electricity.
Variable Flame Remote*: Variable Flame remote safety pilots
are also completely battery operated systems and are a step up from a standard
On/Off remote because they give you the ability
to control the flame height directly from the remote control. Variable Flame
remotes are slightly more costly due to the motorized control
valve attached to the pilot assembly.
Electronic Ignition Remote*:
Electronic ignition systems are the latest technology. The are battery operated
systems that have a remote control transmitter and receiver that turns the gas on and off
electronically so there is no safety pilot burning when the logs are off.
Therefore, there is no wasted gas or noise from a gas pilot during non-operation.
This is the most expensive type of system, but the most desired.
*All remote control safety pilots also have the ability to be operated manually
from a switch that is on burner safety pilot, so if you cannot find your remote,
you can still use the logs.

Fireplace Installation Manuals
Find out if your fireplace is approved for ventless or vented gas logs
If you have a prefabricated wood burning fireplace, you must first determine if it is approved for gas logs and, if so, if it is approved for vented gas logs, vent free gas logs or both. In order to make that determination, you must refer to the owners manual where it will tell you explicitly what is approved. If you do not have a copy of your fireplace owners manual, you may be able to download it from our archive of fireplace installation manuals below that we have accumulated over the years. Hopefully you can find your manual here and determine what type of gas logs it is approved for.
FYI: Vented gas logs are typically referred to in technical terms as a "Decorative Gas Appliance". You will find that most prefab fireplaces are approved for and have instructions for installing a decorative gas appliance. In most cases the manual will specifically say that the decorative gas appliance must have an automatic shutoff, which means you will be required to have a safety pilot...not a match-light system. Ventless gas logs are NOT a decorative gas appliance and are referred to as an unvented heater, ventless heater or some other similar use of the words ventless, vent free or unvented. If the manual does not explicitly say it is approved for a ventless appliance in whatever terms it uses, then it is NOT approved for use with ventless gas logs.
If you cannot locate the manual for your fireplace, please email me some pictures of your fireplace along with the brand name and model number. There should be a label inside your fireplace somewhere close to the opening on either side or at the top where you can find that info. Please be sure to include a legible picture of that label and I will see if I can locate a manual for it and add it to this archive. Email your pictures to: email@example.com
