How to Measure for Gas Logs
Front Width x Back Width x Depth


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! Read more about Clearances Here!
