HEATER AREA
Keep the area near the heater clear and free from
combustible materials, gasoline and other flammable
liquids and vapors.
COMBUSTION AND VENTILATION AIR
The combustion and ventilation air supply must not be

Do not put anything in or on the heater cabinet.
For better circulation and more effective heating, do not
place obstructions, furniture or other items closer than four
feet to the front of the cabinet or two feet from each side
of the cabinet.
CLEANING BLOWER (IF EQUIPPED)
Shut off electricity. Clean any lint or dirt from fan blades,
fan motor and exposed air passages. Annually put two
drops of SAE 20 oil in each of the two cups or oil tubes.
PILOT BURNER
Light the pilot using the instructions in OPERATING YOUR
HEATER. Leave the thermostat at the lowest setting.
The pilot flame should surround 1/2 to 5/8 inches of the
generator tip. If the flame needs adjusting, do it as follows:
ADJUST PILOT BURNER

Turn the screw counterclockwise to increase the flame,
clockwise to decrease.

burners should light quickly and smoothly. Turn the
