Basic Description
Your direct vent wall furnace is shipped ready to install
against an exterior wall up to 9 inches thick. For walls
greater than 9 inches, and up to 24 inches thick, use an
optional VENT EXTENSION KIT listed under OPTIONAL
ACCESSORIES.
The furnace may burn either Natural or L.R Gas, depend-
ing on the model you have purchased.
No electric power is required unless furnace is equipped
with an optional blower accessory.
Always consult your local heating or plumbing inspector,
building department or gas utility company regarding
regulations, codes or ordinances which apply to the in-
stallation of a direct vent furnace.
The sealed combustion system draws combustion air
directly from outdoors into the combustion chamber and
combustion gases are discharged directly to the outdoors
through tubes mounted to the rear of the furnace.
The furnace heat exchanger is built of heavy gauge steel
treated for corrosion resistance.
The furnace cabinet is also constructed of heavy gauge
steel and has an enamel paint finish.
The furnace controls are located behind an access door
on the lower front of the furnace. All models are equipped
with American Gas Association and Canadian Gas
Association listed gas valves and pilots.
