Some paper media high efficiency filters, some-
times identified as HEPA filters can do an effective
and excellent filtration of the air; however, some
models may also cause a large pressure drop
across the filter. The contractor should access the
capabilities of the duct system to deliver sufficient
air flow if this type of filter is considered.
RECOMMENDED: Electronic air filters using electro-
static precipitation to remove dust are an excellent fil-
tration device. A 16" x 25" model is an ideal fit with this
furnace in the case of a side mounted return air inlet.
The furnace control module is supplied with electrical
terminals for use with electronic air cleaners.
A 16" x 25" x 1" filter kit part number 550001458
can be ordered for use on this appliance. This kit
includes the filter rack and washable filter.
NOTE: If two return air inlets are used, both must be
equipped with filters.
!
CAUTION
Do not operate the furnace for prolonged
periods of time without an air filter.
A portion of the dust entrained in the air may
lodge in the supply air ductwork and reg-
isters. Any recirculated dust particles will
be heated and charred by contact with the
furnace heat exchanger. This residue will soil
ceilings, walls, drapery, carpets, and other
household articles.
LUBRICATION
Both the induced draft blower motor and circulat-
ing fan motor are ball-bearing type motors. Neither
requires routine lubrication.
IMPORTANT: The motor bearings were pre-lubri-
cated by the motor manufacturer. Do not attempt
to lubricate them. Excess lubrication will void the
warranty, shorten the service life if the motors,
and will attract the buildup of dust and dirt.
The induced blower motor and circulating fan motor
must be cleaned on a periodic basis by a qualified
service technician. Dust buildup in the ventilation
ports of the motor will cause the motor to not dissi-
pate heat properly resulting in reduced service life.
The combustion air and exhaust terminals should
be inspected occasionally to ensure that they are
free of obstructions and debris. If screens were
used in either terminal, ensure that they are free of
debris, corrosion, or anything preventing the free
flow of air.
The combustion air intake piping and exhaust pip-
ing should be inspected periodically for sags, evi-
dence of leakage etc. If either condition exists, con-
tact your installation contractor, service agency or
fuel supplier.

WARNING
HOLES IN THE EXHAUST PIPING OR FUR-
NACE HEAT EXCHANGER CAN ALLOW
TOXIC FUMES TO ENTER THE HOME AND
CIRCULATE THROUGH THE DUCT SYSTEM
RESULTING IN CARBON MONOXIDE POI-
SONING OR DEATH. IF LEAKS ARE FOUND
IN THE FURNACE HEAT EXCHANGER, IT
MUST BE REPLACED.
OPERATING TIPS
1. Clean air filters maximize efficiency and re-
duce heating costs.
2. During the heating season, keep windows and
doors closed to reduce the heating load on the
system.
3. Avoid excessive use of kitchen exhaust hoods
and other exhaust fans to reduce the heating
load on the system.
4. Arrange the furniture and drapes so that the
supply air registers and return air grilles are un-
obstructed.
5. If you have a perimeter duct system, ideally,
the warm air should bathe the cold exterior walls.
Avoid the use of plastic deflectors on the sup-
ply air registers which tend to short circuit the
warm air straight into the return air grilles. These
deflectors are often the cause of cool draughts
across the floor.
6. Avoid placing heat producing appliances such
as televisions, radios, lamps, etc. in a location to
influence the thermostat.
