Furnace.
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.
The furnace may burn either Natural or propane gas, depending
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 installation 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 outdoors through tubes on the rear of the
furnace.
The furnace cabinet is also constructed of heavy-gauge steel and
has a powder paint nish.
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 (AGA/CGA) listed
gas valves and pilots.
