NORMAL MAINTENANCE
CAUTION: Prior to any of the following maintenance proce-
dures, shut off all power to the unit, to avoid per-
sonal injury.
Periodic maintenance consists of changing or cleaning filters
and lubricating the venter motor. Under some conditions, the
main burners should be cleaned.
FILTERS - Inspect once a month. Replace Disposable or clean
Permanent Type as necessary. DO NOT replace Permanent
Type with Disposable.
MOTORS - Indoor and outdoor fan motors are permanently
lubricated and require no maintenance. Venter motor is factory
lubricated for an estimated 10 year life. Motor may be oiled
annually using 6 drops of Anderaol 402 to extend its life.
CAUTION: DO NOT over-lubricate venter motor.
OUTDOOR COIL - Dirt should not be allowed to accumulate
on the outdoor coil surface or other parts in the air circuit.
Cleaning should be as often as necessary to keep the coil
clean. Use a brush, vacuum cleaner attachment, or other
suitable means. If water is used to clean the coil, be sure that
the power to the unit is shut off prior to cleaning.
NOTE: Exercise care when cleaning the coil so that the coil
fins are not damaged.
Do not permit the hot condenser air discharge to be
obstructed by overhanging structures or shrubs.
BURNER - At the beginning of each heating season, make a
visual check of the main burner flame. If it is not possible to
adjust for the proper flame, the burners may need cleaning.
TO CLEAN BURNERS - Remove them from the furnace as
explained in “Burner Instructions”. Clean burners with hot
water applied along top of the burner.
COMBUSTION AIR DISCHARGE - Visually inspect discharge
outlet periodically to insure soot and dirt buildup is not exces-
sive. If necessary, clean to maintain adequate combustion air
discharge.
The manufacture recommends that the furnace system be
inspected once a year by a qualified service person.
CLEANING FLUE PASSAGES AND HEATING ELEMENTS
With proper combustion adjustment the heating element of a
gas fired furnace will seldom need cleaning. If the element
should become sooted, it can be cleaned as follows:
1. Remove the burner assembly as outlined in “BURNER
INSTRUCTIONS”.
2. Remove the screws holding the flue collector box.
3. Unscrew and lift out the flue baffles.
4. Using a wire brush on a flexible wand, brush out the inside
of each heat exchanger from the burner inlet and flue outlet
ends.
5. Brush out the inside of the flue collector box and the flue
baffles.
6. If soot build-up is particularly bad, remove the vent motor
and clean the wheel and housing.
7. After brushing is complete, blow all brushed areas with air
or nitrogen. Vacuum as needed.
8. Replace parts in the order they were removed in steps 1
thru 3.
