LUBRICATION
The indoor blower motor sleeve
bearings and induced draft motor are
prelubricated and DO NOT require
attention for an indefinite period of
time.
A qualified installer, service agency,
or gas supplier should clean the
motor periodically to prevent the
possibility of overheating due to an
accumulation of dust or dirt on the
windings and the motor exterior. If
the motor needs cleaning, clean the
blower wheel also. A blower wheel
loaded with dirt or dust has reduced
air flow and can cause furnace
overheating, tripping the limit. It can
also cause excessive vibration.
Exercise care if sliding the blower
assembly into the shelf track. The
rear flange must engage properly.
This procedure should be done by a
qualified technician.
As suggested, clean or replace the
air filters. Dirty filters restrict airflow
and adversely affect blower and
furnace operation.
HEAT EXCHANGER
The furnace should operate for many
years without excessive scale build-
up in the flue passageways.
However, a qualified service
technician should inspect the flue
passageways, the venting system
and the burners for continued safe
operation, paying particular attention
to deterioration from corrosion or
other sources. The heat exchanger
passages and vent system should be
inspected by a qualified technician
annually.
A WARNING: HOLES IN THE
VENT PIPING OR HEAT
EXCHANGER CAN ALLOW TOXIC
FUMES TO ENTER THE HOME
RESULTING IN CARBON
MONOXIDE POISONING OR
DEATH. REPLACE THE VENT PIPE
OR HEAT EXCHANGER IF LEAKS
ARE FOUND.
The manufacturer recommends that
at the beginning of the heating
season, a qualified installer, service
agency or gas supplier visually
inspect the main burners and heat
exchanger for proper flame
characteristics, the secondary heat
exchanger for lint and dust build up,
and the furnace for proper operation.
If the flames are distorted and/or
there is evidence of back pressure,
check the vent and inlet air system
for blockage. If there is carbon and
scale in the heat exchanger tubes,
the heat exchanger assembly should
be replaced.
FLAME SENSOR
At the beginning of the heating
season the flame sensor should be
cleaned with steel wool. A qualified
service technician should do this
procedure. This insures continued
flame sensing and proper furnace
operation.
