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:
WARNING: 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.
Filter maintenance procedure:
Shut off the electrical power to the unit. Open the access door. Slide the air filter out of the filter rack.
Clean the filter by either vacuuming, rinsing with tap water, hosing, or dipping in an ordinary detergent
solution. After cleaning and drying the filter, replace the completely dry filter in the rack. If the filter has a
supporting mesh, the mesh side of the filter must be placed towards the furnace.
