How To Care For Your Heater

-- DO NOT refinish with wall paint.

SERIES ONLY)
For ease of cleaning, access or replacement of internal
parts, the top of this heater can be removed by following
these steps: Refer to Fig. 6.

heater sides.
HEATER AREA
Keep the area near the heater clear and free from com-
bustible materials, gasoline, and other flammable liquids
and vapors.
COMBUSTION AND VENTILATION AIR
The combustion and ventilation air supply must not be
blocked
Do not put anything in or on the heater cabinet.
For better circulation and more effective heating, do not
place obstructive furniture closer than four feet to the front
of the cabinet or two feet to the side of the cabinet.
CLEANING BURNER COMPARTMENT
Because cold air is attracted to the flame during furnace
operation, a build up of lint from bedding and dust (etc.)
in the burner area will occur each heating season. It is
necessary to clean this area regularly. Use a vacuum
cleaner with a narrow attachment to reach small areas.
Be careful in and around the pilot. A change in its adjust-
ment could be made if struck during cleaning.
DANGER
A BUILDUP OF ANY DUST, LINT OR FOREIGN
MATERIAL IN THE PARIMARY AIR OPENING OF
THE BURNER CAN INTERFERE WITH THE PRO-
PER AIR GAS MIXTURE AND CAN RESULT IN A
YELLOW FLAME WHICH CAN PRODUCE CAR-
BON MONOXIDE AND SOOT. THIS CONDITION IF
ALLOWED TO DEVELOP, CAN LEAD TO BODILY
INJURY INCLUDING DEATH. IT IS IMPERATIVE
THAT THE BURNER BE KEPT CLEAN.
