• If the furnace is installed horizontally, the furnace
access doors must be vertical so that the burners
re horizontally into the heat exchanger. Do not
install the unit with the access doors on the “up/top”
or “down/bottom” side of the furnace.
• Do not connect this furnace to a chimney ue that
serves a separate appliance designed to burn solid
fuel.
• Counterow installation over a noncombustible oor.
Before setting the furnace over the plenum opening,
ensure the surface around the opening is smooth
and level. A tight seal should be made between the
furnace base and oor by using a silicon rubber
caulking compound or cement grout.
• Counterow installation over a combustible oor.
If installation over a combustible floor becomes
necessary, use an accessory subbase (see
Specication Sheet applicable to your model for
details). A special accessory subbase must be used
for upright counterow unit installations over any
combustible material including wood. Follow the
instructions with the subbase for proper installations.
Do not install the furnace directly on carpeting, tile, or
other combustible material other than wood ooring.
(NOTE: The subbase will not be required if an air
conditioning coil is installed between the supply
air opening on the furnace and the oor. The air
conditioning coil must be downstream from the heat
exchanger of the furnace.

• Adequate combustion/ventilation air must be supplied
to the closet.
• Furnace must be completely sealed to floor or
base. Combustion/ ventilation air supply pipes must
terminate 12” from top of closet and 12” from oor
of closet. DO NOT remove solid base plate for side
return.
• Return air ducts must be completely sealed to
the furnace and terminate outside the enclosure
surfaces.
• Ensure the temperature of the return air entering the
furnace is between 55°F and 100°F when the furnace
is heating.
• Provisions must be made for venting combustion
products outdoors through a proper venting system.
The length of ue pipe could be a limiting factor in
locating the furnace.
• Ensure adequate combustion air is available for the
furnace. Improper or insufcient combustion air
can expose building occupants to gas combustion
products that could include carbon monoxide. Refer
to Combustion and Ventilation Air Requirements
section.
• The furnace must be level. If the furnace is to be set
on a oor that may become wet or damp at times,
the furnace should be supported above the oor on
a concrete base sized approximately 1-1/2” larger
than the base of the furnace.
• Ensure upow or horizontal furnaces are not installed
directly on carpeting, or any other combustible
material. The only combustible material allowed is
wood.
• Exposure to contaminated combustion air will result
in safety and performance-related problems. Do
not install the furnace where the combustion air is
exposed to the following substances:
chlorinated waxes or cleaners
chlorine-based swimming pool chemicals
water softening chemicals
deicing salts or chemicals
carbon tetrachloride
halogen type refrigerants
cleaning solutions (such as perchloroethylene)
printing inks
paint removers
varnishes
hydrochloric acid
cements and glues
antistatic fabric softeners for clothes dryers
and masonry acid washing materials
• If the furnace is used in connection with a cooling
unit, install the furnace upstream or in parallel with the
cooling unit coil. Premature heat exchanger failure
will result if the cooling unit coil is placed ahead of
the furnace.
• For vertical applications, the minimum cooling coil
width shall not be less than furnace width minus 1”.
Additionally, a coil installed above an upow furnace
or under a counterow furnace may be the same width
as the furnace or may be one size larger than the
furnace. Example: a “C” width coil may be installed
with a “B” width furnace.
• For upow applications, the front of the coil and
furnace must face the same direction.
• If the furnace is installed in a residential garage,
position the furnace so that the burners and ignition
source are located not less than 18 inches (457 mm)
above the oor. Protect the furnace from physical
damage by vehicles.
