Our fire pit has a dual ring burner (rusted) with lava rock and the flame is blue. Should there be an air flow adjustment? Is the stainless steel burner better? We are considering the glass but still might use the logs. What do you think?

Our Answer:

Most likely, the blue flame is being caused by a fuel mixture that is too "rich" or fuel heavy. There should be an air shutter or air valve that can be opened to balance the incoming air to the burner assembly. This is usually located on or near the gas valve for the unit. Stainless steel is definitely the preferred material for outdoor use, as it not only stands up to precipitation, but can more readily deal with the large volumes of moist air that is drawn into the pit for combustion. Fire glass is becoming increasingly popular, both for the contemporary look and for the low maintenance aspect of the glass. The glass can last for years and requires virtually no maintenance.
