• Instruct children on the safety haz-
ards associated with furnaces. Keep
children away from the furnace at all
times.
FILTER MAINTENANCE
Have your qualified installer, service
agency or the gas supplier instruct you
on how to access your filters for regular
maintenance.
• Keep air filters clean at all times.
Vacuum dirt from filter, wash with
detergent and water, air dry thorough-
ly and reinstall.
• After filters are cleaned and returned
to the furnace, be sure doors are
properly reinstalled. If you are not
totally sure of this procedure, consult
qualified installer, service agency or
the gas supplier.
REMOVING FILTERS
FILTER IN BOTTOM OR SIDE
LOCATION
1. Remove the blower compartment
access door.
2. Disengage the filter retaining rod and
pull filter out.
3. Clean filter and reinstall.
4. Replace the blower compartment
access door.
LUBRICATION
The blower motor and induced draft
motor are permanently lubricated by
the manufacturer and do not require
further attention.
IMPORTANT: DO NOT
ATTEMPT TO
LUBRICATE THE BEARINGS ON THE
BLOWER MOTOR OR THE INDUCED
DRAFT BLOWER MOTOR. ADDITION
OF LUBRICANTS CAN REDUCE THE
MOTOR LIFE AND VOID THE WAR-
RANTY.
The blower compartment and motor
should be inspected and cleaned peri-
odically by your qualified installer, ser-
vice agency or the gas supplier to pre-
vent the possibility of overheating due
to an accumulation of dust and dirt on
the windings or on the motor exterior.
And, as suggested elsewhere in these
instructions, keep the air filters clean
because dirty filters can restrict airflow
and the motor depends on sufficient air
flowing across and through it to keep it
from overheating.
COMBUSTION AIR AND
VENT SYSTEM
1. It is recommended that an annual
inspection of your furnace’s combus-
tion air and vent system be done by
a qualified installer, service agency
or the gas supplier.
2. Turn OFF the electrical supply to the
furnace and remove the access
doors.
3. Inspect the gas burners for dirt, rust
or scale and clean as necessary.
4. Inspect the flue connection area and
vent pipe. Be sure that the vent con-
nector is in place and slopes upward
and is physically sound, without
holes or excessive corrosion.
5. Be sure that the return air duct con-
nections are physically sound, are
sealed to the furnace casing and ter-
minate outside the space containing
the furnace.
