GENERAL INFORMATION
DESCRIPTION
This Category IV, dual certified direct vent and 1-pipe vent
furnace is designed for residential or commercial applica-
tion. It may be installed without modification to the conden-
sate system in a basement, garage, equipment room, alcove,
attic or any other indoor location provided the space tempera-
ture is 32 °F or higher and where all required clearance to
combustibles and other restrictions are met. If the furnace is
being installed where the space temperature is below 32°F,
refer to "BELOW FREEZING LOCATIONS" on page 4.
This furnace is constructed at the factory for natural gas-fired
operation at 0 - 4,500 ft. above sea level, but may be con-
verted to operate on propane (LP) gas and at altitudes up to
10,000 ft. For applications at altitudes between 2,000 - 4,500
ft., see "COMBUSTION AIR AND VENT SYSTEM" on
page 14, for required vent length reductions. For applications
at altitudes greater than 4,500 feet, see high altitude instruc-
tions 035-14460-000.
High altitude and propane (LP) changes or conversions
required in order for the appliance to satisfactory meet the
application must be made by an authorized distributor or
dealer. In Canada, a certified conversion station or other
qualified agency, using factory specified and/or approved
parts, must perform the conversion.
INSPECTION
As soon as a unit is received, it should be inspected for possi-
ble damage during transit. If damage is evident, the extent of
the damage should be noted on the carrier's freight bill.
A separate request for inspection by the carrier's agent
should be made in writing. Also, before installation the unit
should be checked for screws or bolts which may have loos-
ened in transit. There are no shipping or spacer brackets
which need to be removed.
NOTES, CAUTIONS & WARNINGS
The installer should pay particular attention to the words:
NOTE, CAUTION and WARNING. NOTES are intended to
clarify or make the installation easier. CAUTIONS are given
to prevent equipment damage. WARNINGS are given to alert
the installer that personal injury and/or equipment or property
damage may occur if installation procedures are not handled
properly.
The cooling coil must be installed in the supply air
duct, downstream of the furnace. Cooled air may
not be passed over the heat exchanger.
