GENERAL
This multipoise furnace is shipped in packaged configuration.
Some assembly and modifications are required when used in
any of the four applications shown in Figure 4.
This furnace must:
• be installed so the electrical components are protec-
ted from water.
• not be installed directly on any combustible material
other than wood flooring for upflow applications.
Downflow installations require use of a factory-ap-
proved floor base or coil model numbers END4X,
ENW4X or coil casing model number NAEA when
installed on combustible materials or wood flooring
(refer to SAFETY CONSIDERATIONS).
• be located as close to the chimney or vent and at-
tached to an air distribution system. Refer to Air
Ducts section.
• be provided ample space for servicing and cleaning.
Always comply with minimum fire protection clear-
ances shown on the furnace clearance to combust-
ible label.
The following types of furnace installations may require
OUTDOOR AIR for combustion due to chemical exposures:
• Commercial buildings
• Buildings with indoor pools
• Laundry rooms
• Hobby or craft rooms, and
• Chemical storage areas

CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal
injury or death, and unit component damage.
Corrosive or contaminated air may cause failure of
parts containing flue gas, which could leak into the
living space. Air for combustion must not be
contaminated by halogen compounds, which include
fluoride, chloride, bromide, and iodide. These
elements can corrode heat exchangers and shorten
furnace life. Air contaminants are found in aerosol
sprays, detergents, bleaches, cleaning solvents,
salts, air fresheners, and other household products.
Do not install furnace in a corrosive or contaminated
atmosphere. Make sure all combustion and
circulating air requirements are met, in addition to all
local codes and ordinances.
A02097
If air is exposed to the following substances, it should not be
used for combustion air, and outdoor air may be required for
combustion:
• Permanent wave solutions
• Chlorinated waxes and cleaners
• Chlorine based swimming pool chemicals
• Water softening chemicals
• De-icing salts or chemicals
• Carbon tetrachloride
• Halogen type refrigerants
• Cleaning solvents (such as perchloroethylene)
• Printing inks, paint removers, varnishes, etc.
• Hydrochloric acid
• Cements and glues
• Antistatic fabric softeners for clothes dryers
• Masonry acid washing materials
