Maintenance
Keep the area around the burner clear and free of combustible materials, gasoline and other
flammable liquids or vapors. Do not obstruct burner air inlet slots or ventilation grilles for com-
bustion air.
■ ■ ■ ■ The motor features permanently lubricated ball bearings and requires no routine oiling mainte-
nance.
IMPORTANT: Check the burner flame periodically. A proper NATURAL gas flame will appear blue
at the burner face with orange and yellow tips. A proper PROPANE gas flame will appear blue at
the burner face with yellow tips. If the flame is too rich, it will appear billowy and yellow with
hazy tips. If too lean, it will appear short and all blue. If the flame does not appear proper,
CON-
TACT A QUALIFIED SERVICE TECHNICIAN FOR CLEANING, READJUSTMENT AND/OR
REPAIR.
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 Main Manual Shut-off
Valve and burner power. A dangerous condition has developed and must be
corrected.
CONTACT A QUALIFIED SERVICE TECHNICIAN FOR CLEANING READJUST-
MENT AND/OR REPAIR.
WARNING: If PROPANE gas is used and the burner is located in a base-
ment, crawl space or confining space, contact your gas supplier about
installing a GAS LEAK warning device. PROPANE gas is heavier than air and
can settle in low areas or confined spaces. This would create a danger of
explosion or fire. If you suspect a gas leak, follow instructions on front cover
of this manual.
