How To Care For Your Furnace
DANGER: PERSONAL INJURY HAZARD. DISCONNECT ELECTRIC POWER BEFORE
SERVICING.
ANNUAL UPKEEP NEEDED
CLEANING AND OILING CABINET FINISH
Remove cabinet door and front panel. Clean any lint
or dirt from fan blades, fan motor, air shutters and
exposed air passages. Use a brush.
Put 5 drops of SAE 20 non-detergent oil in each of the
two oil cups on fan motor. Replace front panel and
cabinet door (Fig. 1).
VENTING SYSTEM
Make sure that no parts of the venting system are
blocked or rusted. Clean or replace before using
furnace.
BURNER AND PILOT FLAME
Look at the burner flame. See "Checks and
Adjustments". Contact Sears Service Department at
once if an abnormal flame appearance should
develop (Fig. 27).
Apply a small amount of furniture wax to a soft cloth
and wipe cabinet. Never use abrasives or clean
when furniture is hot.
FURNACE AREA
The area near the furnace must be kept clear and
free from combustible materials, gasoline, and other
flammable liquids and vapors.
COMBUSTION AND VENTILATION AIR
The combustion and ventilation air supply must not
be blocked. See page 5.
Do not put anything in, on or under the furnace
cabinet.
If you wish, call for a Sears service technician to perform this maintenance for you. The peace of mind and assured
performance are well worth the cost involved.
