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.
