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 upper front panel.
2. Depress red manual reset button. The manual reset vent safety
switch is located on the draft diverter.
3. Replace upper 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.

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.
