NFPA 54, ANSI Z223.1/Canadian Installation Code,
CAN/CGA B149.

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
inches into the wall, with studs 16 inches center-to-center
or stud space can be framed to 16 inches, see page 11,
Recessed Mounting.
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 instatl the furnace in a closet, alcove, of small hallway
where the furnace could be isolated by closing doors to the
heater space.
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
CABINET
that is at teast the same size as the bottom of the furnace.
On recessed installations the recessed portion rnay 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
location. 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 gases 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 on Page 8,
Figure 2 and Page 8, Figure 3.
The top of the furnace must be at least 4 inches from the
ceiling. See Figure 2.
With standard furnace discharge outlet, do not install
closer than 4 inches to intersecting wall. See figure as
shown on Page 8, Figure 3B.
When using optional kits 6703 or 6704 maintain
clearances as shown on Page 8, Figure 3A or 3C.
When using optional kit 6704 maintain clearance as shown in
Figures 3A and 3F, page 8. Use only optional outlet and grille
