MAIN BURNER FLAME CHARACTERISTICS
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.

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
Electrical 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 receptacle. 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 receptacle 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
doorways with a heat source in an adjoining room.
Do Not Install
Thermostat on Outside Wall.
CAUTION:
Label all wires prior to disconnection when
servicing controls. Wiring errors can cause improper and
dangeros operation. Verify proper operation after servicing.
