Minimum firebox size for each burner

Every burner has a smallest fireplace it can go into. In one maker's table, the 18/20 inch burner calls for a firebox no narrower than 26 inches across the front and 20 across the back, at least 15 inches deep and 17 inches tall.

Its 24 inch burner needs 30 inches at the front and 24 at the back, and its 30 inch burner 36 and 29, with the same depth and height. Our crew measures all four dimensions in your firebox and compares them with the table for the set you want.

• Front width
• Rear width, measured at the burner's depth
• Depth from the opening
• Height of the opening

Sand for natural gas, vermiculite for propane

The loose material in a burner pan spreads the gas and shapes the flame. One maker's vented sets use sand on natural gas and vermiculite on propane, with glowing embers placed on top.

Using the wrong media for the gas type is on the same manual's list of causes for a low flame, and media packed down too tightly can make a burner light unevenly. Our installers use the media your set specifies and spread it the way the manual shows.

Dual-fuel vent-free sets

Some vent-free sets ship ready for one gas and can be changed to the other. One manual describes a set shipped for propane that a qualified installer can convert to natural gas by following its instructions and markings, with no other field conversion allowed.

Our crew confirms which gas your home uses before installation and completes any conversion the manual allows, then marks the set so the next technician knows how it is configured.

Purging air from a new supply line

A new or reopened gas line is full of air, and air does not light. One maker's troubleshooting table lists air in the gas line as a reason a pilot will not light and says to bleed the supply line and repeat the lighting steps until the air is gone.

Our installers purge the line as the manual describes before the first light, which spares you a set that clicks and clicks on its first evening.

A log set that has been under water

Flood water ruins gas controls. One vented set manual says a set with any part that has been under water stays off until a qualified service technician has inspected it and replaced every part of the control system and every gas control that got wet.

The same manual warns that attempted operation may result in fire or explosion. Our technicians follow that rule even when a wet set seems to light, and they list the replacement parts on a written estimate.
