ALTERNATE ELECTRICAL AND GAS LINE CONNECTIONS
This furnace has provisions allowing for electrical and gas line
connections through either side panel. In horizontal applications
the connections can be made either through the “top” or “bot-
tom” of the furnace.
DRAIN PAN
A drain pan must be provided if the furnace is installed above a
conditioned area. The drain pan must cover the entire area
under the furnace (and air conditioning coil if applicable).
FREEZE PROTECTION
Refer to Horizontal Applications and Conditions - Drain Trap and
Lines.

P ROPANE G AS /H IGH A LTITUDE I NSTALLATIONS
This furnace is shipped from the factory configured for natural
gas at standard altitude. Propane gas installations require an
orifice and spring change to compensate for the energy content
difference between natural and propane gas.
High altitude installations may require both a pressure switch
and an orifice/spring change. These changes are necessary to
compensate for the natural reduction in the density of both the
gas fuel and the combustion air at higher altitude.
For installations above 7000 feet, please refer to the furnace
Specification Sheets for required kit(s).
For furnaces being converted to LP gas, it is strongly recom-
mended that a LPLP03 kit also be installed. The use of this
kit will prevent the furnace from firing when the LP gas sup-
ply pressure is too low to support proper combustion.
Contact the distributor for a tabular listing of appropriate
manufacturer’s kits for propane gas and/or high altitude instal-
lations. The indicated kits must be used to insure safe and
proper furnace operation. All conversions must be performed by
a qualified installer, or service agency.
V ENT /F LUE P IPE & C OMBUSTION A IR P IPE
This manual will refer to the pipe that discharges products
of combustion to the outdoors as the “vent” pipe or “flue”
pipe. The pipe that supplies air for combustion to the fur-
nace will be referred to as the “intake” pipe or “combustion
air” pipe. A condensing gas furnace achieves its high level of
efficiency by extracting almost all of the heat from the products
of combustion and cooling them to the point where condensation
