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 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"
(22mm) 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' (1.2m) to 5' (1.5m) 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.
To Conserve Gas: Turn off pilot when heater is not in use.
Insulated Vent Enclosure
Vented wall furnaces installed in buildings with flat roofs can have
poor venting. The cold vent pipe will have a delay in proper venting
and cause the wall furnace to shut "OFF" by the vent safety switch.
To prevent delayed venting as well as condensation of flue products
an insulated vent enclosure is recommended.
Use type B vent pipe and maintain at least a one inch (25mm)
clearance to combustibles.
Use metal thimble to protect vent pipe as it passes through
combustibles.
Vent Safety Shutoff System
This appliance must be properly connected to a venting system.
This appliance is equipped with a vent safety shutoff system.

Warning: Operation of this wall furnace when not connected
to a properly installed and maintained venting system or
tampering with the vent safety shutoff system can result in
carbon monoxide (CO) poisoning and possible death.
This furnace is equipped with a manual reset vent safety switch.
The manual reset vent safety switch will cause gas flow to the main
burners to "shut off" due to improper venting or a blocked flue.
To reset the manual reset vent safety switch:
1. Remove front panel.
2. Depress manual reset button. The manual reset vent safety
switch is located on the draft diverter.
3. Replace front panel.
If the manual reset vent safety switch continues to "shut off" the
gas flow to the main burners a qualified service person must be
contacted to inspect for improper venting, blockage in the vent pipe
or the manual reset vent safety switch for being defective.
