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.

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.

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.

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.
