Before installing the furnace, refer to the current edition of the
NFGC. Canadian installations must be installed in accordance with
NSCNGPIC and all authorities having jurisdiction. For further
information, the National Fuel Gas -Code is available from Na
tional Fire Protection Association Inc. Batterymarch Park, Quincy,
MA 02269, American Gas Association, 1515 Wilson Boulevard,
Arlington, VA 22209, or from Literature Distribution.
Installation must conform to the regulations of the serving gas
supplier and the local building, heating, and plumbing codes in
effect in the area in which the installation is made, or in the
absence of local codes with the requirements of the NFGC.
A CAUTION
Application of this furnace should be indoors with special
attention given to vent sizing and material, gas input rate, air
temperature rise, and unit sizing. Improper installation or
misapplication of the furnace can require excessive servicing
or cause premature component failure.
This furnace is designed for a minimum continuous return-air
temperature of 60°F db or an intermittent operation down to 55°F
db such as when used with a night setback thermostat. Return-air
temperature must not exceed a maximum of 85°F db.

A WARNING
Improper installation, adjustment, alteration, service, mainte
nance, or use can cause carbon monoxide poisoning, explo
sion, fire, electrical shock, or other conditions which may
cause personal injury or property damage. Consult a qualified
installer, service agency, local gas supplier, or your distribu
tor or branch for information or assistance. The qualified
installer or agency must use only factory-authorized and
listed kits or accessories when modifying this product. A
failure to follow this warning can cause electrical shock, fire,
personal injury, or death.
For accessory installation details, refer to the applicable instruction
literature.
NOTE: Remove all shipping brackets and materials before
operating the furnace.
step 1—Location
GENERAL
A CAUTION
Do not install furnace in a corrosive or contaminated atmo
sphere. Make sure all combustion and circulating air require
ments are met, in addition to all local codes and ordinances.
A CAUTION
Do not use this furnace during construction when adhesives,
sealers, and/or new carpets are being installed. If the furnace
is required during construction, use clean outside air for
combustion and ventilation. Compounds of chlorine and
fluorine when burned with combustion air form acids which
will cause corrosion of the heat exchangers and metal vent
system. Some of these compounds are found in paneling and
dry wall adhesives, paints, thinners, masonry Ci-aning mate
rials, and many other solvents commonly used in ihe con
struction process.
This furnace must be installed so the electrical components are
protected from water.
Locate the furnace close to the chimney/vent and as near the center
of the air distribution system as possible. The furnace should be
installed as level as possible.
When a furnace is installed so that the supply ducts carry air to
areas outside the space containing the furnace, the return air must
also be handled by a duct(s) ’ sealed to the furnace casing and
terminating outside the space containing the furnace.
Provide ample space for servicing and cleaning. Always comply
with the minimum fire protection clearances shown on the unit
rating plate.
LOCATION RELATIVE TO COOLING EQUIPMENT - The
cooling coil must be installed parallel with or on the downstream
side of the furnace to avoid condensation in the heat exchangers.
When installed parallel with a furnace, dampers or other means
used to control the flow of air must prevent chilled air from
entering the unit. If the dampers are manually operated, they must
be equipped with means to prevent operation of either unit unless
the damper is in the full-heat or full-cool position.
HAZARDOUS LOCATIONS - When the furnace is installed in
a residential garage, it must be installed so that the burners and
ignition source are at least 18 in. above the floor. The furnace
should be protected from physical damage by vehicles. When a
furnace is installed in public garages, airplane hangars, or other
buildings having hazardous atmospheres, the unit must be installed
in accordance with the recommended good practice requirements
of the National Fite Protection Association, Inc.
Step 2—Air For Combustion and Ventilation
Provisions for adequate combustion and ventilation air must be
provided in accordance with Section 5.3, Air for Combustion and
Ventilation, of the NFGC or applicable provisions of the local
building codes.
Canadian installations must be installed in accordance with NSCNGPIC and all authorities having jurisdiction.
A CAUTION
Air for combustion must not be contaminated by halogen
compounds, which include fluoride, chloride, bromide, and
iodide. These elements are found in aerosol sprays, deter
gents, bleaches, cleaning solvents, salts, air fresheners, and
other household products.
All fuel-burning equipment must be supplied with air for combus
tion of the fuel. Sufficient air MUST be provided to ensure there
will not be a negative pressure in the equipment room or space. In
addition, a positive seal MUST be made between the furnace
cabinet and the return-air duct to prevent pulling air from the
burner area and draft safeguard opening.
A CAUTION
The operation of exhaust fans, kitchen ventilation fans,
clothes dryers, or fireplaces could create a NEGATIVE
PRESSURE CONDITION at the furnace. Make-up air MUST
BE PROVIDED for the ventilation devices, in addition to that
required by the furnace.
Combustion air requirements are determined by whether the
furnace is in an UNCONFINED or CONFINED space.
UNCONFINED SPACE — An unconfined space must have at
least 50 cu ft for each 1000 Btuh of input for all the appliances
(such as furnaces, clothes dryer, water heaters, etc.) in the space.
For Example:
58WAV FURNACE
INPUT BTUH
44,000 293
66,000 440
88,000
110,000 733
132,000 880
154,000 1026
If the unconfined space is of unusually tight construction, air for
combustion and ventilation MUST come from either the outdoors
or spaces freely communicating with the outdoors. Combustion
and ventilation openings must be sized the same as for a confined
space. A minimum opening with a total of at least 1 sq in. per 5000
Btuh of total input rating for all equipment must be provided.
Return air must not be taken from the room, unless an equal or
greater amount of air is supplied to the room.
CONFINED SPACE — A confined space is one whose volume is
less than 50 cu ft per 1000 Btuh of the total output rating for all
appliances installed in that space. A confined space MUST have 2
permanent openings, 1 within 12 in. of the ceiling and the other
within 12 in. of the floor. (See Fig. 2.)
NOTE: In determining the free area of an opening, the blocking
effect of the louvers, grilles, and screens must be considered. If the
free area of a louver or grille design is unknown, it may be
assumed that wood louvers have a 20 percent free area and metal
louvers or grilles have a 60 percent free area. Screens, when used,
must not be smaller than 1/4-in. mesh. Louvers and grilles must be
constructed so they cannot be closed.
The size of the openings depends upon whether the air comes from
inside or outside of the structure.
1. All air from inside the structure:
Each opening MUST have at least 1 sq in. of free area per
1000 Btuh of the total input for all equipment within the
confined space, but not less than 100 sq in. per opening. (See
Fig. 2.)

If the building is constructed unusually tight, a permanent opening
directly communicating with the outdoors should be provided.
This opening shall have a minimum free area of 1 sq in. per 5000
Btuh of total input rating for all equipment in the enclosure.
If the furnace is installed on a raised platform to provide a
return-air plenum, and return air is taken directly from the hallway
or space adjacent to the furnace, all air for combustion must come
from outdoors.
2. AJil air from outside the structure:
a. If combustion air is taken from outdoors through vertical
ducts, the openings and ducts MUST have at least 1 sq in.
of free area per 4000 Btuh of the total input for all
equipment within the confined space. (See Fig. 3.)
When ducts are used, they must be of the same cross-sectional area
as the free area of the openings to which they connect. The
minimum dimension of rectangular ducts must not be less than 3
in. (See Fig. 3.)
A WARNING
Do not install the furnace on its back; safety control operation
will be adversely affected. Never connect return-air ducts to
the back of the furnace. A failure to follow this warning can
cause a fire, personal injury, or death.
Step 3—Filter Arrangement
The factory-supplied filter(s) is shipped in the blower compart
ment. Determine location for the filter and move filter retaining
hardware, if necessary, before attaching the return-air duct. After
the return-air duct has been connected to the furnace, install the
filter(s) inside the furnace blower compartment. See Fig. 4 for side
return application and Fig. 5 for bottom return application.
A bottom closure panel is factory installed in the bottom of the
furnace. When bottom return inlet is desired, remove and discard
the enclosure panel.
Filter retaining brackets, supports, and retainers are factory as
sembled and shipped installed for side return application, with 1
set of all required hardware on each of the furnace. (See Fig. 4.)
For bottom return applications, remove the brackets (front and
back) and supports from each side. The back bracket(s) are
installed in the rear of the furnace casing (dimples are provided to
mark mounting screw locations).
The front bracket(s) are installed on the bottom front plate as
shown in Fig. 5, once the bottom enclosure has been removed.
Rotate filter supports 180° so filter will rest on support, and
reinstall. (Do not reinstall in 17-1/2 in. casing.) Install the filter
retaining rod (small U-shaped end) in the rear bracket, and the
front of the filter retainer rod as shown in Fig. 5. Two sets of
hardware are needed for furnaces in 24-1/2 in. casings using 2
filters for bottom return. All hardware is provided for filter
installation.
