Company regarding regulations, codes, or ordinances
which apply to the installation of a vented wall furnace.
Obtain professional help where needed.
The CHECK AND ADJUSTMENTS on page 24 are vital
to the proper and safe operation of the furnace. Be sure
they are done.

ing 4 inches, side wall 4 inches. For exception to

air.
Locating Wall Furnace & Thermostat
Consider the following points before attempting to install
the furnace:
CAUTION

ing in the attic for ceiling joist locations and proposed
venting.
The counterflow vented wall furnaces are shipped ready
to install on the surface of the wall or recessed up to 9-1/4

Place the furnace near the center of the space to be
heated for good air circulation. Do not put it behind a door
or draperies.
Do not install the furnace in a closet, alcove, or small
hallway where the furnace could be isolated by closing
doors to the heater space. See Fig. 2 for the minimum
clearances.
Do not install the furnace in a mobile home, trailer, or
recreational vehicle.
The bottom of the furnace may rest directly on a wood or
concrete floor. If floor is other than wood or concrete there
must be a piece of wood or sheet metal under the furnace
that is at least the same size as the bottom of the furnace.
On recessed installations the recessed portion may have
0 inches clearance to combustible material.
To provide adequate clearance and service access the
front of the furnace must face the open room. Be sure that
gas piping and electrical wiring can be brought to the loca-
tion. See sections covering piping and electrical wiring for
your type of furnace mounting.
Furnace vent must be installed directly to the outdoors so
that combustion gasses will not collect inside the building.
Provide an adequate vent or flue in accordance with local
codes or ordinances and instructions provided by the vent
pipe manufacturer.
Check the minimum spacing needs as shown in Figs. 2
and 3, pages 6 and 7.
The top of the furnace must be at least 4 inches from the
ceiling. See Fig. 2.
With standard furnace discharge outlet, do not install
closer than 4 inches to intersecting wall. See Fig. 3B,
page 7.
When using optional kits 6703 or 6704 maintain clearances
as shown in Figs. 3A or 3C, page 7.
When using optional kit 6704 maintain clearance as shown
in Figs. 3A and 3F, page 7. Use only optional outlet and
grille kits available from manufacturer.
