WARNING:
To avoid electric shock, personal injury,
or death, disconnect the electric power
before performing any maintenance.
WARNING:
Holes in the vent pipe or heat exchang-
er can cause products of combustion
to enter the home. Replace the vent
pipe or heat exchanger if leaks are
found. Failure to prevent products of
combustion from being circulated into
the living space can create potentially
hazardous conditions including car-
bon monoxide poisoning that could
result in personal injury or death.
Combustion Air and Vent System
Check the combustion air and vent pipe to ensure
that it is not damaged, corroded or blocked by
debris. Any damaged section of vent pipe must be
replaced, and any obstruction or blockage must
be removed prior to operating the furnace.
WARNING:
Never operate the furnace without
a fi lter in place. Dust and lint in the
return air can build up on internal
components, resulting in loss of
effi ciency, equipment damage, and
possible fi re.
Air Filter(s)
Air fi lter(s) are not supplied with the furnace
as shipped from the factory. Filters for side
return and bottom return applications are
available from your local distributor.
The installer should provide a fi lter rack for a high
velocity type fi lter in the return air duct adjacent
to the furnace. Filters should be changed or
cleaned monthly during the heating season.
New or newly renovated homes may require
more frequent changing until the construction
dust has been removed.
Lubrication
The bearings in the circulating air blower motors
are pre-lubricated and sealed at the factory. No
further oiling of the bearings is required for the
life of the motor.
Condensate Drain Assembly
Be sure the condensate lines are free and open
(i.e. avoid kinking hoses). Also make sure all
hose clamps are tight to avoid drawing air into
the system.
Blower Compartment
The blower compartment should be cleaned
monthly during the heating and cooling seasons
to remove any dirt and lint that may have ac-
cumulated in the compartment or on the blower
and motor. Dirt and lint can create excessive
loads on the motor resulting in higher than
normal operating temperatures and shortened
service life.
Heat Exchanger and Burner Maintenance
The furnace should operate for many years
without excessive soot buildup in the fl ue pas-
sageways, however, the fl ue passageways,
the vent system, and the burners should be
inspected and cleaned (if required) by a quali-
fi ed serviceman annually to ensure continued
safe operation. Particular attention must be
given to identify deterioration from corrosion or
other sources.
SYSTEM OPERATION
INFORMATION
Proper maintenance is most important to achieve
the best performance from a furnace. Follow
these instructions for years of safe, trouble free
operation.
• Do not place combustible materials on or
against the furnace cabinet or the vent
pipe.
• Do not store gasoline or any other fl am-
mable vapors and liquids in the vicinity of
the furnace.
• Change or replace the air fi lters monthly
during any period when the circulating
blower is operating regularly.
• Always replace the doors on the furnace
after servicing. Do not operate the furnace
without all doors and covers in place.
• Avoid operating the furnace when windows
and doors are open.
• Be sure that the thermostat is properly
installed and is not being affected by drafts
or heat from lamps or other appliances.
