4) This furnace is equipped with an electronic ignition system that automatically
lights the burner. DO NOT try to light the burner by hand.
5) Turn on the electric power to the furnace at the disconnecting switch.
6) Adjust the room thermostat to the desired setpoint and set the operating mode, if

TO INTERRUPT (STOP) OPERATION OF THIS FURNACE:
1) Adjust the room thermostat to the lowest setpoint and set the operating mode, if
equipped, to “OFF”.
2) If service will be performed, turn off all electric power to the furnace at the
disconnecting switch.
3) Turn the manual oil shutoff valve to the closed or “OFF” position.
Oil Supply
• If available, the use of ultra-low or low sulfur (less than 0.0015% S and 0.0015 -
0.05% S, by weight, respectively), no. 2 fuel oil is highly recommended. Low
sulfur fuel oil can help to significantly reduce instances of blockage and corrosion of
the oil burner fuel delivery system, including the nozzle, the furnace heat exchanger,
and the flue gas vent system. These benefits can appreciably decrease or eliminate
service calls due to poor fuel quality. Air pollutants emitted by the furnace as well as
the typical malodorous smell of oil combustion will also be reduced. Consult your fuel
oil supplier about the availability of low-sulfur, fuel oil.
• DO NOT allow the fuel tank to run completely dry during the heating season. If the
fuel tank runs completely dry, it may be necessary to purge the oil lines of trapped
air. If necessary, contact a qualified heating contractor to bleed the oil lines and
restart the burner.
• During the warmer weather, keep the tank full to prevent condensation of moisture
on the inside surface of the tank. The presence of moisture in the tank is beneficial
to the growth of biological fuel contaminants (bacteria, mold, fungus, yeast, etc.).
• Keep the cap on the fuel tank fill pipe tightly closed at all times to prevent the
entrance of moisture, foreign matter, insects, etc. Consider adding a guard or filter to
the tank vent pipe to reduce the entrance of water and foreign matter into the tank.
Also, check the tank, vent, and fill pipe for cracks and leaks. Have any necessary
tank repairs performed ASAP.
