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 tem-
perature. Is thermostat 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 burn-
er 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 representative. For your
convenience, record furnace product
and serial numbers on page 2.

mation needed by your service rep-
resentative.
