ted from water.
S
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).
S
be located close to the chimney or vent and attached
to an air distribution system. Refer to Air Ducts sec-
tion.
S
be provided ample space for servicing and cleaning.
Always comply with minimum fire protection clear-
ances shown on the furnace clearance to combust-
ible construction label.

OUTDOOR AIR for combustion due to chemical exposures:
S
Commercial buildings
S
Buildings with indoor pools
S
Laundry rooms
S
Hobby or craft rooms, and
S
Chemical storage areas
If air is exposed to the following substances, it should not be
used for combustion air, and outdoor air may be required for
combustion:
S
Permanent wave solutions
S
Chlorinated waxes and cleaners
S
Chlorine based swimming pool chemicals
S
Water softening chemicals
S
De−icing salts or chemicals

FIRE, INJURY OR DEATH HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
When the furnace is installed in a residential garage, the
burners and ignition sources must be located at least 18
in. (457 mm) above the floor. The furnace must be
located or protected to avoid damage by vehicles. When
the furnace is installed in a public garage, airplane
hangar,
atmosphere,
accordance with the NFPA 54/ANSI Z223.1−2012 . (See
Figure 5)
FIRE HAZARD
Failure to follow this warning could result in personal
injury, death and/or property damage.
Do not install the furnace on its back or hang furnace
with control compartment facing downward. Safety
control operation will be adversely affected. Never
connect return−air ducts to the back of the furnace.
(See Figure 6)
LOCATION RELATIVE TO COOLING EQUIPMENT
The cooling coil must be installed parallel with, or on the
downstream side of the unit to avoid condensation in the heat
exchangers. When installed parallel with the furnace, dampers
or other flow control must prevent chilled air from entering the
furnace. 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.
Specifications are subject to change without notice.
