WARNING
Explosion Hazard
Keep flammable materials and vapors, such as
gasoline, away from furnace.
Place furnace so that burners are at least 18 inches
(46 cm) above the floor for a garage installation.
Failure to follow these instructions can result in death,
explosion, or fire.
WARNING
Explosion Hazard
Do not install this furnace in a mobile home.
Doing so can result in death, explosion, fire, or
carbon monoxide poisoning.
IMPORTANT: Do not use the furnace as a heater in a building
under construction. The furnace can be severely damaged due to
the abnormal environment caused by construction. Chlorides
from sources such as paint, stain, or varnish; tile and counter
cements; adhesives; and foam insulation are abundant in a
structure under construction and can be highly corrosive. Low
return air temperature can cause condensation in the furnace and
other damage that can shorten the life of the furnace.
The condensate system must not be exposed to
temperatures below 32°F (0ºC). Insulating condensate
system in areas exposed to temperatures below 32ºF (0ºC) is
necessary.
The furnace is suitable for installation in buildings
constructed on site. The furnace should be centralized in
respect to the heat distribution system as much as
practicable.

Location Requirements

To avoid property damage caused by condensate drain
blockage, install a field-fabricated auxiliary drain pan with a
separate drain line to the outside under the entire furnace and
drain system. Install according to local codes.
All models are suitable for closet or utility room installation.
Utility room installation requires:
A door opening large enough for the widest part of the
furnace.
A door opening large enough to remove/replace any other
appliance located in the utility room, such as a water heater.
Any other appliances arranged so that each appliance can be
removed/replaced without disturbing the furnace.
In a residential garage, a gas-fired furnace must be installed
so the burner(s) and the ignition source are located not less
than 18" (45.7 cm) above the floor. The furnace is to be
located or protected to avoid physical damage by vehicles.
Furnaces may be installed as suspended units in the
horizontal position. These furnaces are not designed for
direct attachment of suspension rods to the furnace casing.
See "installation Configurations."
If the furnace is to be installed in an attic or other insulated
space, it must be kept free and clear of insulating materials.
Furnaces may be installed as upflow or horizontal furnaces.
When the furnace is installed horizontally, secure the furnace
door by installing a sheet metal screw through the side and
door on the upper left-hand side of the furnace.
Installation Clearances
A 2" (5.1 cm) minimum clearance is required in front for air
openings into the combustion chamber.
All servicing and cleaning of the furnace can be performed
from the front. If installed in a closet or utility room, provide
24" (61 cm) clearance in front for service if the door to the
room is not in line with the front of the furnace. Where
servicing clearances are greater than clearances to
combustibles, servicing clearances take precedence.
