Now that you’ve gone through the steps of making the really broad decisions in selecting your gas logs, it’s time to get a little more specific. This is the point at which most gas log shoppers begin narrowing down the vast selections of ventless or vented gas logs based on things like fireplace size considerations, types of controls, pilot systems vs. manual gas valves, and others. On this page, we’ll take a look at each of the factors that can really make a difference in choosing the right gas logs.
If you’re going with ventless gas logs that come in their own cabinet you don’t have to worry too much about the size. For the rest of you, though, selecting a set of gas logs that you like and that fits properly within your fireplace is a must. You can simply use the handy-dandy gas log calculator located here on eFireplaceStore.com, but let’s run through some basic size considerations so you know exactly what you’re looking for.
As promised, here’s where we take a closer look at the three main types of gas log fuel control systems. Check them out to see how each works and which system appeals to you, then we’ll wrap this page up with a quick look at the sizing implications of each system.
|Manual On/Off Valve||Manual Safety Pilot Valve||Millivolt (Remote-ready) Pilot Valve|
|This is the simplest type of fuel control system, the one many of us used in years past. You turn a manual on/off valve open and closed by hand, light the gas log burner with a match, and adjust the flame height via the valve by hand, as well.||This fuel control system is similar to that used on a furnace or water heater. There are ‘Off’, ‘Pilot’, and ‘On’ positions. Initially you have to turn the valve to the ‘Pilot’ position and light the pilot with a match, but after that you can turn the gas logs on and off by switching between the ‘On’ and ‘Pilot’ positions. The pilot will stay lit until turned to ‘Off’ or blown out, at which point it automatically shuts off gas flow. Propane gas logs require a safety pilot valve of some kind.||This is very similar to a manual safety pilot valve, except a remote-ready pilot valve can be connected to an optional device to remotely turn the gas on or off or control the flame height. These devices range from inexpensive remotes or wall switches designed only to turn the gas on and off to more expensive remotes that can adjust flame heights and set timers, or even thermostats that will turn the flame down once the desired temperature is reached.|
Some final tips to give you an idea about how each gas log fuel control system affects the size gas log set you need. This reference is somewhat general and some gas log sets may have individual space requirements, so read the information about individual gas log sets carefully!
|Manual On/Off Valve||Manual Safety Pilot Valve||Remote-ready Pilot Valve|
|No pilot kit is involved, so all you need is 2 inches of clearance between the burner system and the fireplace on each side. Measure the fireplace’s front opening width, subtract 4 inches, and the resulting length is the largest size gas log set your fireplace can accommodate.||The safety pilot valve occupies some space, so again measure the front opening width of the fireplace, but subtract 8 total inches rather than the 4 inches required for the manual on/off valve. The resulting measurement is the largest gas log set equipped with a manual safety pilot valve your fireplace can handle.||This is about the same as the manual safety pilot valve calculation, but in this case subtract 12 inches from the opening width to find the largest gas log set equipped with a remote-ready pilot valve suitable for your fireplace.|
