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.
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.
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.
