DANGER: The gas burner in this direct gas-fired system is designed and equipped to provide
safe and economically controlled complete combustion. However, if the installation does not
permit the burner to receive the proper supply of combustion air, complete combustion may
not occur. The result is incomplete combustion which produces carbon monoxide, a poisonous
gas that can cause death.
Always comply with the combustion air requirements in the installation codes and operating
instructions. The amount of air over the burner must be within the specified range. The burner
profile plates are set at the factory to match CFM requirements. Do not adjust the burner
profile plates without contacting a factory representative. FAILURE TO PROVIDE PROPER
COMBUSTION AIR CAN RESULT IN A HEALTH HAZARD WHICH CAN CAUSE PROPERTY
DAMAGE, SERIOUS INJURY, AND/OR DEATH. Direct-fired installations should provide for
air changes as required by the applicable installation codes.
