Basic Description
Your Counterflow Top Vented Wall Furnace is shipped
ready to install on the surface of a wall or recessed up to
9-1/4 inches in a wall, with wall studs spaced 16 inches
center to center.
Vent piping and exhaust are not part of the Williams fur-
nace package and must be purchased separately.
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 counterflow top vented wall furnace.
Air is drawn in at the top by the fan and discharges through
a grille near the floor. A two-speed fan is used with Model
50087;55083 and 65087 series. A single speed fan is us-
ed on all other models. The furnace contains a multi-slot
burner (two on Model 50087; 55083 and 65087 series) and
burns either Natural or L.P (Liquefied Petroleum) Gas,
depending on the model you have purchased.
The furnace controls are located behind an access door
on the lower front of the furnace. All models are equipped
with American Gas Association listed gas valves and pilots.
The combustion system draws combustion air directly from
the room in which the furnace is installed, and through ven-
tilation grills or ducts connected to the outdoors, such as an
attic or crawl space. The combustion gases are discharged
through the roof within a listed vent pipe
The furnace heat exchanger is built of heavy gauge steel
treated for corrosion resistance. The fan at the top forces
air down along the front, back and sides of the heat
exchanger where it is discharged into the room. The fur-
nace cabinet is also constructed of heavy gauge steel and
has an enamel paint finish.
Models 3508331; 3508332; 5508331 and 5508332 are
equipped with an electronic ignitionautomatic pilot relight
system.
This appliance is equipped with a vent safety shutoff sys-
tem designed to protect against improper venting of com-
bustion products. Operation of this wall furnace when not
connected to a properly installed and maintained ventil-
lating system or tampering with the vent safety shutoff sys-
tem can result in carbon monoxide (CO) poisioning and
possible death.
