CONSUMER INSTRUCTIONS

?

Keep the area around the burner clear and free of combustible material,  gasoline or other

flammable liquids or vapors. Do not obstruct burner air openings or ventilation grills for
combustion air.

?

The motor features permanently lubricated ball bearings and requires no maintenance.

WARNING: If any flame is observed when the burner is on standby, or if the

ignition spark or valve operator is heard to come on before the motor reaches
operating speed, immediately turn off the manual gas control and burner power. A
dangerous condition has developed and must be corrected. CONTACT A QUALIFIED
SERVICE TECHNICIAN FOR CLEANING, READJUSTMENT OR REPAIR.

?

Check that the pilot ignition spark does not come on before the motor reaches operating

speed. If it does, the air switch is defective and must be replaced. (See Section X, Motor /
Blower Interlock).
