Ventilation and Combustion Air
Wall furnaces shall be installed in a location in which the facilities
for ventilation permit satisfactory combustion of gas and proper
venting under normal conditions. In buildings of conventional
frame, brick, or stone construction without tight storm windows
and doors, infiltration is normally adequate to provide air for com
-
bustion and draft hood dilution.
Where appliances are installed in confined and unconfined
spaces within a building, the building being of unusually tight
construction, air for combustion and ventilation must be obtained
directly from outdoors or from such spaces that freely communi-
cate with the outdoors. Under these conditions, the confined and
unconfined spaces shall be provided with two permanent open
-
ings, one near the top of the enclosure and one near the bottom;
each opening shall have a free area of not less than one square
inch (6.45cm
2
) per 2,000 BTU hr. (.6KW/H) of total input.
Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equip-
ment or accessories and repair and servicing of equipment shall
be performed only by a qualified agency. The term “qualified
agency” means any individual, firm, corporation or company
which either in person or through a representative is engaged
in and is responsible for (a) the installation or replacement of
gas piping or (b) the connection, installation, repair or servicing
of equipment, who is experienced in such work, familiar with all
precautions required and has complied with all the requirements
of the authority having jurisdiction.
State of Massachusetts:
The installation must be made by a
licensed plumber or gas fitter in the Commonwealth of Mas
-
sachusetts.
The installation must conform with local codes or, in the absence
of local codes, with the National Fuel Gas Code, ANSI Z223.1/
NFPA 54* Natural Gas and Propane Installation Code, CSA
B149.1.

Clearances
1. In selecting a location for installation , it is necessary to provide
adequate accessibility clearances for servicing and proper
installation.
2. The FAW-55 can be attached to the wall or recessed into the
wall up to 4 inches (102mm) in depth.
3. The wall in which the furnace is recessed has (0) zero (0mm)
clearance to the furnace sides and top.
4. When using side discharge registers, SOR-1 or SOK-1, the
furnace cannot be recessed into the wall.
5. Clearance to sidewall or combustible material is 4 inches
(102mm).
6. Ceiling clearance is 7 1/2 inches (191mm)
7. Floor and rear wall clearance is (0) zero inches (0mm).
8. Clearance of 18 inches (457mm) is required to adjacent wall
or combustible material when flushed mounted SOR-1, side
outlet register is used.
Before Installing Consider The Following Venting
1. A chimney for residential-type or low-heat gas utilization equip-
ment shall extend at least 3 feet (914mm) above the highest
point where it passes through a roof of a building and at least
2 feet (610mm) higher than any portion of building within a
horizontal distance of 10 feet (3m).
2. This furnace must not be connected to a chimney flue serving
a separate solid-fuel burning appliance.
3. Uninsulated Single-Wall Metal Pipe shall not be used outdoors
in cold climates for venting gas utilization equipment.
4. Attention! This Fan Type Vented Wall Furnace is equipped with
a vent safety switch. In the event of spillage of flue products
due to improper venting the vent safety switch will open, which
results in the main burners to “shut off.”
Refer to Figure 1 and Page 12 for additional information regarding
U.L. Listed gas vent equipment.
Installing Optional Side Outlets
Side outlet register, SOR-1 may be installed on one or both sides
of the furnace at the required clearances of 18 inches (457mm) to
adjacent wall or combustible material as shown in Figure 2.
1. Locate and cut the 5 1/2” (140mm) square opening in the cabinet
side using the template from the kit, exposing the inner liner
knock-out.
2. Remove the knock-out.
3. Place the register on the 5 1/2” (140mm) opening with the
louvers set for the desired direction and mark the mounting
holes using the register as a template.
4. Drill two (2) 1/8” (3mm) diameter holes in cabinet side and
fasten the register in place with two (2) #10 x 1” (25mm) screws
provided.
Side outlet kit, 10” (254mm) boot assembly with register, SOK-1 for
warm air discharge into an adjoining room may be installed on either
side of the furnace at the required clearance of 4 inches (102mm)
to adjacent wall as shown in Figure 3A.
1. Locate and cut the 5 1/2” (140mm) square opening in the cabinet
side using the template from the kit, exposing the inner liner
knock-out.
2. Remove the knock-out.
3. Using the inner and outer boots as hole templates, mark and
drill (8) 1/8” (3mm) diameter holes in the inner liner and cabinet
side.
4. Using Figure 3A locate and cut a 6 3/4” (171mm) square open-
ing through walls.
5. Attach furnace to wall (see
Attaching Furnace to Wall
).
6. With furnace in place, after checking alignment of side outlet
opening in wall and furnace, place the 9 3/8” x 9 3/8” (238mm
x 238mm) side outlet wall plate over outer boot, pass the outer
boot through the wall and attach side outlet wall plate to furnace
