•Check flue and secondary tube pas- sage ways including chimney — clean if necessary.

•Change oil filter.

•Check and adjust combustion and draft.

•Inspect all vent piping inside struc- ture for deterioration and vent termi- nations 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 fil- ter if necessary.

•Inspect all supply- and return-air ducts for obstructions, air leaks, and insulation. Remedy any problem when necessary.

•Inspect the return-air duct connec- tions at the furnace to ensure it is physically sound, sealed to the fur- nace casing, and terminates outside the space containing the furnace.

•Inspect electrical wiring, connec-

tions, and components for loose con- nections.

•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 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. Should you ever require service, you will have ready access to the infor- mation needed by your service rep- resentative.
