Page 52

D. STARTING THE BURNER:

1.Turn the main service switch to "OFF" position.

2.Set thermostat substantially above room temperature.

3.Open shut-off valves in oil supply line to burner.

4.Turn service switch to furnace "ON". If burner starts and runs, but stops again on lockout, it may be necessary to bleed the lines or make burner combustion air adjustments. Contact a qualified service person to adjust and start burner.

E. FILTER CLEANING AND LOCATION:

χWARNING: To avoid injury from moving parts, hot surfaces, or electrical shock, shut off the power to the furnace before removing any furnace access doors to service the air filters.

The air filters should be inspected each month and cleaned when dirty. Cleaning the air filters frequently may reduce airborne contaminants from entering the furnace and depositing in the furnace, duct system and home.
