Introduction
Please read our instructions before you install and use your furnace. This will help you obtain the full value from this fur-
nace. It could help you avoid needless service costs, if the answer to the problem is found within this instruction manual.
Basic Description
Vented wall furnaces are shipped ready to install in a
2 x 4 stud wall, with studs 16 inches center to center.
Always consult your local heating or plumbing inspector,
building department or gas utility company regarding
regulations, codes or ordinaces which apply to the installa-
tion of a vented wall furnace.
No electric power is required unless furnace is equipped
with an optional blower accessory.
The efficiency rating of this appliance is a product ther-
mal efficiency rating determined under continuous
operating conditions and was determined independent of
any installed system.
Single wall models described in this manual, are install-
ed in a 2 x 4 stud wall between studs spaced 16 inches
center to center, or may be surface mounted to a wall us-
ing free standing kit 4901.
Warmed air is discharged into the room in which the fur-
nace is located.
The furnace contains a single multi-slot gas burner.
Combustion air is drawn in from the room where the fur-
nace is located and is vented out of the top of the furnace
vertically through vent piping in the stud space to a roof
vent top. (Vent equipment is not supplied with furnace, but
may be obtained from WILLIAMS.)
Convection causes room air to circulate from the floor up-
ward along the front, back, and side of the heat exchanger,
and then back to the room.
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 a neutral
beige color enamel paint finish. The front of the cabinet
is fully Iouvered.
The furnace controls are located behind an access door
on the lower front of the furnace. All models are equipped
with AGA/CGA listed gas valves and pilots.
Models: 2509611, 2509612, 3509611, 3509612, 5009611,
5009612 are equipped with a built-in thermostat control.
Models: 2509621, 2509622, 3509621, 3509622, 5009621,
5009622 are supplied with a wall thermostat.
NOTE, ALL MODELS:
This appliance is equipped with a vent safety shutoff
system, designed to protect against improper venting of
combustion products. Operation of this wall furnace when
not connected to a properly installed and maintained ven-
ting system or tampering with the vent safety shutoff
system can result in carbon monoxide (CO) poisoning and
possible death.
