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
combustion 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 communicate with the
outdoors. Under these conditions, the confined and unconfined
spaces shall be provided with two permanent openings, 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 equipment
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.
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.
*Available from the American National Standards Institute, Inc., 11 West 42nd St.,
New York, N.Y. 10036.
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 flush 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
equipment 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).
INSTALLATION
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 16 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 (2) 1/8” (3mm) diameter holes in cabinet side and fasten the
register in place with (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 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
opening 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
side of wall with (2) #10 x 1” (25mm) screws provided.
7. Fasten outer boot to the cabinet side with (4) #8 x 1/4” (6mm)
screws provided.
8. Position and attach inner boot to inner liner with (4) #8 x 1/4”
(6mm) screws provided.
9. Locate the register with its louvers positioned for the desired
air discharge direction and mark the mounting holes using the
register as a template.
10. Drill (2) 1/8” (3mm) diameter holes in the wall and fasten the
register in place with (2) #10 x 1” (25mm) screws provided
