MAINTENANCE
It is recommended that the furnace be checked
yearly. At a minimum, this check should include
the following items.
!
WARNING:
To avoid electric shock, personal in-
jury, or death, disconnect the electric
power before performing any mainte-
nance.
!
WARNING:
Holes in the vent pipe or heat ex-
changer can cause products of com-
bustion 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 condi-
tions including carbon monoxide poi-
soning 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.
Air Filter(s)
!
WARNING:
Never operate the furnace without a
filter in place. Dust and lint in the
return air can build up on internal
components, resulting in loss of effi-
ciency, equipment damage, and pos-
sible fire.
AIR FILTER(S) ARE NOT SUPPLIED WITH THE
FURNACE AS SHIPPED FROM THE FACTORY.
FILTERS FOR SIDE RETURN AND BOTTOM
RETURN APPLICATIONS ARE AVAILABLE
FROM NORDYNE DISTRIBUTORS.
The installer should provide a filter rack for a
high velocity type filter 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 accu-
mulated 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 flue pas-
sageways, however, the flue passageways, the
vent system, and the burners should be in-
spected and cleaned (if required) by a qualified
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 flam-
mable vapors and liquids in the vicinity of
the furnace.
