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.
The clean burner port disconnect the gas supply to the valve, and
remove the screws fastening the burner. After removing the burner
door from the burner box, remove each main burner. Pilot mount-
ing bracket will need to be unscrewed and moved out 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 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.
Optional 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 servic
-
ing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
To Conserve Gas: Turn off pilot when heater is not in use.
