REGULAR DEALER MAINTENANCE
Heat Exchanger
NOTE: To ensure dependable and efficient heating
operation, the heat exchanger should be checked by a
qualified maintenance person before each heating season,
and cleaned when necessary.
EQUIPMENT DAMAGE HAZARD
Failure to follow this caution may result in damage to
equipment.
This checkout should not be attempted by anyone not
having the required expertise and equipment to do the
job properly.
CAUTION
!
Checking and/or cleaning the heat exchanger involves
removing the gas controls assembly and the flue collector
box cover. When finished, the gas controls must be
reinstalled for proper operation. Also, the flue collector
box cover must be replaced correctly, with “red” RTV, so
that a proper seal is maintained. Contact your dealer for
the required periodic maintenance. At the beginning of
each cooling/heating season and as conditions require.
Fans and Belts, and Fan Motor

belt tension and fan motor shaft bearings. No lubrication of
condenser or evaporator fan bearings or motors is required or
recommended.

checked and cleaned at the same time the cooling coils are
checked by your dealer.
In addition to the type of routine maintenance you might be
willing to perform, your unit should be inspected regularly
by a properly trained and qualified service technician. An

least every year) should include the following:
S Inspection of all flue product passages, including the
burners, heat exchanger, and flue collector box.
S Inspection of all combustion-- and ventilation--air
passages and openings.
S Close inspection of all gas pipes leading to and inside
your unit.

obstructions, and insulation integrity. Any problems
found should be resolved at the time of inspection.
S Inspection of the unit base for cracks, gaps, etc., which
may cause a hazardous condition.
S Inspection of the unit casing for signs of deterioration.
S Inspection of all electrical wiring and components to
ensure proper connection.
S Inspection for leaks in the refrigerant circuit. Pressure
check to determine appropriate refrigerant charge.
S Inspection of fan wheels and housings, belt tension, and
fan motor shaft bearings.
S Operational check of the unit to determine working
conditions. Repair or adjustment should be made at the
time of inspection.
