NOTE: If filter has been replaced with an electronic
air cleaner (EAC), refer to EAC Owner’s Manual for
maintenance information.
4. If filter is dirty, it must be replaced. If your furnace
air filter needs to be replaced, be sure to use the same
size and type of filter that was originally supplied.
Use furnace filter table for filter size and filter rack
flange dimensions for return air duct.
FURNACE AIR FILTER TABLE
If you have replaced a disposable filter with a perma-
nent washable filter, it may be cleaned if it is dirty.
Wash filter in a sink, bathtub, or outside with a garden
hose. Always use cold tap water. A mild liquid deter-
gent may be used if necessary. Spray water through
filter in the opposite direction of airflow. Allow filter
to dry.
5. Re-install clean air filter.
6. Turn on electrical supply to furnace.
A CHECK-UP CHECKLIST
Your furnace represents an important investment in
your family’s comfort and your home’s value. To keep
it performing properly and as a preventative to future
problems, have a trained service specialist give your
furnace a professional check-up annually. The fol-
lowing checklist can be used as a guideline to proper
service:
• Check flue and secondary tube passage ways including
chimney — clean if necessary.
• Change oil filter.
• Change nozzle.
• Check and adjust combustion and draft.
• Inspect all vent piping inside structure for deterioration
and vent terminations outside the structure for blockage.
• Check oil pipes leading to and inside of your furnace
for leaks.
• Inspect and clean the blower motor and wheel.
• Inspect and change or clean air filter if necessary.
• Inspect all supply- and return-air ducts for obstruc-
tions, air leaks, and insulation. Remedy any problem
when necessary.
• Inspect the return-air duct connections at the furnace to
ensure it is physically sound, sealed to the furnace
casing, and terminates outside the space containing the
furnace.
• Inspect electrical wiring, connections, and compo-
nents for loose connections.
• Examine the physical support of the furnace. Support
should be sound with no cracks, sagging, gaps, etc.
around the base.
• Check furnace for any obvious signs of deterioration.
BEFORE YOU REQUEST
A SERVICE CALL
If your furnace is not operating or not performing
properly, you may save the expense of a service call
by checking a few things yourself before calling for
service.
FOR INSUFFICIENT AIRFLOW:
• Check for dirty air filters.
• Check for blocked return-air or supply-air grilles
throughout your home. Ensure they are open and
unobstructed.
If problem still exists, call your dealer for service.
IF FURNACE FAILS TO OPERATE:
Follow this checklist step by step, advancing to the next
step only if furnace fails to start.
• Check thermostat for proper temperature. Is thermo-
stat set above room temperature?
• Is thermostat set on HEAT?
• Check fuses and circuit breakers. Is electrical supply
on?
• Is valve in oil supply pipe in open position?
• Is the ignition control on the burner not in lockout? The
red button on top of the control must be depressed for 3
sec in order to reset the control.
• Check for obstructions around the vent termination.
If furnace still fails to operate, call your service represen-
tative. For your convenience, record furnace product and
serial numbers on page 2. Should you ever require
service, you will have ready access to the information
needed by your service representative.
