A WARNING
Improper installation, adjustment, alteration, service,
maintenance, or use can cause carbon monoxide poison­
ing, explosion, 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 distributor or branch for information
or assistance. The qualified installer or agency must use
only factory authorized and fisted kits or accessories
when modifying this product. A failure to foUow this
warning can cause electrical shock, fire, personal injury,
or death.
For accessory installation details, refer to the applicable
instruction literature.
NOTE: Remove aU shipping brackets and materials before
operating the furnace.
I. LOCATION
A. General
A CAUTION
Do not install furnace in a corrosive or contaminated
atmosphere. Make sure all combustion and circulating
air requirements are adhered to, in addition to eiU local
codes and ordinances.
Do not use this furnace during construction when adhe­
sives, sealers, and/or new carpets are being installed. If
the fm-nace 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 com­
pounds are: paneling and dry waU adhesives, paints,
thinners, masonry cleaning materials, and many other
solvents commonly used in the construction process.
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 clearemces shown
on the unit rating plate. This furnace shall not be installed
directly on carpeting, tüe, or any combustible material other
than wood flooring.

B. Location With Respect to Cooling Equipment
The coofing 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 fuU-cool position.
C. Hazardous Locations
When the furnace is installed in a residential garage, it must
be installed so that the burners and ignition source are
located no less them 18-ins. above the floor. Also, the fur­
nace should be protected from physical damage by vehicles.
When a furnace is installed in public garages, airplane han­
gars, or other buildings having hazardous atmospheres, the
unit must be installed in accordance with the recommended
good practice requirements of the National Fire Protection
Association, Inc.
II. 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 National Fuel Gas Code,
ANSI Z223.1-1988, or applicable provisions of the local
building codes.
Canadian installations must be installed in accordance with
CAN/CGA.B149 Installation Codes, and aU authorities hav­
ing jurisdiction.
A CAUTION
Air for combustion must not be contaminated by halo­
gen compounds, which include fluoride, chloride, bro­
mide and iodide.
These elements are found in aerosol sprays, detergents,
bleaches, cleaning solvents, salts, air fresheners, and
other household products.
AU fuel burning equipment must be supplied with air for
combustion of the fuel. Sufficient air MUST be provided to
insure there wfll 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 puUing
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.
