left discharge and counterflow furnaces with right air
discharge. This configuration allows the flue and combustion
air piping to be run vertically through the side of the furnace.
Refer to the “Recommended Installation Positions” figure for
further detail. The standard piping connections may also be
used in these positions. Refer to
Vent/Flue Pipe and
Combustion Air Pipe
for details concerning the conversion to
the alternate vent/flue and combustion air connections.
When using the horizontal alternate vent configuration, you
must use the RF000142 vent drain kit. See following
illustration.

NSTALLATIONS
This furnace is shipped from the factory configured for natural
gas at tandard altitude. Propane gas installations require an
orifice change to compensate for the energy content
difference between natural and propane gas.
For furnaces being converted to LP gas, it is strongly
recommended that a LPLP03 kit also be installed. The use
of this kit will prevent the furnace from firing when the LP
gas supply pressure is too low to support proper combustion.
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).

manufacturer’s kits for propane gas and/or high altitude
installations. 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.
