ADHERED TO.
General
These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
having jurisdiction before installation.
These units should not be installed in areas normally
subject to freezing temperatures.
In addition to the requirements outlined previously, the
following general recommendations must 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 non-direct vent
applications, do not install the furnace where drafts
might blow directly into it. This could cause improper
combustion and unsafe operation.
•
When the furnace is installed in non-direct vent
applications, do not block the furnace combustion air
opening with clothing, boxes, doors, etc. Air is needed
for proper combustion and safe unit operation.
•
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.

ALLIED
CAUTION
NOTE: The Commonwealth of Massachusetts stipulates
these additional requirements:
•
Gas furnaces shall be installed by a licensed plumber
or fitter only.
•
The gas cock must be "T handle" type.
•
When a furnace is installed in an attic, the passageway

AIR
Installation
Setting Equipment
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.
Blower access panel must be securely in place when
blower and burners are operating. If panels are left off,
gas fumes, which could contain carbon monoxide, can
be drawn into living space resulting in personal injury
or death.
Improper installation of the furnace can result in
personal injury or death. Combustion and flue products
must never be allowed to enter the return air system or
air in the living space. Use sheet metal screws and joint
tape to seal return air system to furnace.
In platform installations with furnace return, the furnace
should be sealed airtight to the return air plenum. A door
must never be used as a portion of the return air duct
system. The base must provide a stable support and an
airtight seal to the furnace. Allow absolutely no sagging,
cracks, gaps, etc.
For no reason should return and supply air duct systems
ever be connected to or from other heating devices
such as a fireplace or stove, etc. Fire, explosion, carbon
monoxide poisoning, personal injury and/or property
damage could result.
Upflow Applications
This gas furnace can be installed as shipped in the upflow
position. Refer to Figure 5 for clearances.
