Operation Main burner air supply: 1. For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. Primary air supply is controlled by an air shutter on the front of the burner. 2.

Trouble Shooting BURNER PROBLEMS LIFTING BURNER FLAMES: Excessive primary air can cause flames to lift and blow off the burner ports which can be noisy as well as inefficient. More importantly however is the production of dangerous carbon monoxide under this condition.

Trouble Shooting BURNER PROBLEMS– cont’d. FLOATING FLAMES: The difference between floating flames and lifting (or blowing) flames should be clearly understood. Both conditions are undesirable, but the causes and corrective steps are different. Floating flames are lazy looking. They do not have well defined cones, and appear to be “reaching” for the air. They are long, ill- defined, quite flames which roll around in the combustion chamber sometimes completely off the ports.
