MAINTENANCE AND SERVICE

A: ROUTINE MAINTENANCE
HOME OWNER
Other than remembering to arrange for
the annual professional servicing of the
furnace by the service or installation
contractor, the most important routine
service performed by the homeowner is
to maintain the air filter or filters. A dirty
filter can cause the furnace to over-heat,
fail to maintain indoor temperature during
cold weather, increase fuel consumption
and cause component failure.
The furnace filter(s) should be inspected,
cleaned or replaced monthly.
furnace is factory equipped with a semi-
permanent type filter. If the filter is
damaged, replace with filters of the same
size and type.
During the routine service, inspect the
general condition of the furnace watching
for signs of oil leaks in the vicinity of the
oil burner, soot forming on any external
part of the furnace, soot forming around
the joints in the vent pipe, etc. If any of
these conditions are present, please
advice your service or
contractor.

radiator. Clean out all accumulated dirt,
soot and debris with a wire handled
brush and an industrial vacuum cleaner.
Replace the clean-out covers.

permanently lubricated by the motor
manufacturer. These motors will have no
oil ports. If the blower motor does
contain oil ports, under normal operating
conditions it will not require oiling for the
first two years. Oil sparingly; a few drops
in each oil port with SAE 20 non-
detergent oil. Oiling is most easily done
BY
with a "tele-spout" oiler. This oiler has a
long flexible plastic spout. DO NOT
OVER-LUBRICATE. Excess oil may
result in premature electric motor failure.
