Proper Main Burner Flame
The correct flame will be a short, blue inner flame with a much
larger, light blue, outer flame. The burner does not have a primary
air adjustment. The flame will be correct if the factory-set
pressure and orifice opening are used. After the furnace has been
operating, the burner ports may be blocked by foreign matter
carried in by combustion air. Therefore, cleaning of the burner
may be needed for proper flame.
To clean burner port disconnect the gas supply to the valve, and
remove the screws fastening the burner door. After removing the
burner door from the burner box, remove each main burner. Pilot
mounting bracket will need to be unscrewed and moved out of the
way to remove all burners. Burners can be blown out using
compressed air or by blowing through them. Be sure there is no
lint or foreign debris blocking the burner ports. Reassemble using
the same screws earlier removed and locate pilot in the same
position as before and noted above.

Cleaning Combustion (Exchanger) Assembly
A QUALIFIED SERVICE PERSON should remove the
combustion (exchanger) assembly and flue baffles. Apply air
pressure to the inside of the combustion (exchanger) assembly
and flue baffles in order to clear all passageways.
Oiling the Motor
The fan motor should be cleaned and oiled once each heating
season. Oil holes are located on the top at each end of the motor.
Use a few drops of #10 motor oil. To clean the motor, blow air
through its ventilation openings with a vacuum cleaner or low
pressure air source.
Wiring
The appliance, when installed, must be electrically grounded in
accordance with local codes or, in the absence of local codes, with
the National Electrical Code, ANSI/NFPA 70 or Canadian Elec-
trical Code, CSA C22.1, if an external electrical source is utilized.
This appliance is equipped with a three-prong [grounding]
plug for your protection against shock hazard and should be
plugged directly into a properly grounded three-prong recep-
tacle. Do not cut or remove the grounding prong from this
plug. For an ungrounded receptacle, an adapter, which has two
prongs and a wire for grounding, can be purchased, plugged into
the ungrounded receptacle and its wire connected to the recep-
tacle mounting screw. With this wire completing the ground, the
appliance cord plug can be plugged into the adapter and be
electrically grounded. A 7/8" hole is provided in the junction box
for use with a conduit connector if local codes require this type of
protection.
Thermostat Installation
The thermostat should be installed in the same room as the
furnace 4' to 5' above the floor and away from another heat source
(cooking stove, hot water heater, etc.) including walls and door-
ways with a heat source in an adjoining room. Do Not Install
Thermostat on Outside Wall.
