•
Air filters must be replaced upon construction completion.
•
The input rate and temperature rise must be set per the
furnace rating plate.
•
One hundred percent (100%) outdoor air must be provided
for combustion air requirements during construction.
•
The furnace heat exchanger, components, duct system,
air filters and evaporator coils must be thoroughly
cleaned following final construction cleanup.
•
All furnace operating conditions (including ignition, input
rate, temperature rise and venting) must be verified
according to these installation instructions.
These units should not be installed in areas normally
subject to freezing temperatures.
CAUTION
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
having jurisdiction before installation.
In addition to the requirements outlined previously, the
following general recommendations should be considered
when installing one of these furnaces:
•
Place the furnace as close to the center of the air
distribution system as possible. The furnace should
also be located close to the vent termination point.
•
When the furnace is installed in an attic or other
insulated space, keep insulation away from the furnace.
•
When the furnace is installed in an unconditioned space,
consider provisions required to prevent freezing of
condensate drain system.
Installation – Setting Equipment
Select a location that allows for the required clearances
that are listed on the unit nameplate. Also consider gas
supply connections, electrical supply, vent connection,
condensate trap and drain connections, and installation and
service clearances (24 inches [610 mm] at unit front). The
unit must be level from side to side, for proper operation.
It
is recommended to tilt the unit slightly toward the drain to
insure proper drainage. See Figure 4.
The State of California has determined that this product
may contain or produce a chemical or chemicals, in

WARNING
General
Figure 4
Setting Equipment
Do not install the furnace on its front or its back. See
Figure 5. Do not connect the return air ducts to the
back of the furnace. Doing so will adversely affect the
operation of the safety control devices, which could
result in personal injury or death.
