The appliance, when installed, must be electrically grounded in ac-
cordance 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
dangerous operation. Verify proper operation after servicing.

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 com-
pressed 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.
