See “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 “Alternate Flue/Vent
Location” illustration.
NOTE: Alternate vertical piping connections cannot be used
when an upflow furnace is installed with the supply air
discharging to the right, or when a counterflow furnace is installed
with the supply air discharging to the left. In either case, use the
standard flue and combustion air piping connections.
Alternate Flue/Vent Location
NOTES:
■
The field supplied drain hose is connected from the vent/drain
connection to the condensate drain line with a field supplied
connector.
■
Make a small loop in the drain hose to serve as a P-trap.
Recommended Installation Positions—Upright Upflow

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 bottom 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.”
Furnace Suspension
If the furnace is installed in a crawl space, it must be suspended
from the floor joist or supported by a concrete pad.
NOTE: Never install the furnace on the ground or allow it to be
exposed to water. Refer to “Location Requirements and
Considerations—Furnace Suspension” for further details.
PROPANE GAS/HIGH ALTITUDE
INSTALLATIONS
This furnace is shipped from the factory configured for Natural
gas at standard altitude. Propane gas installations require an
orifice 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.

Possible property damage, personal injury or death may
occur if the correct conversion kits are not installed. The
appropriate kits must be applied to ensure safe and proper
furnace operation. All conversions must be performed by
a qualified installer or service agency.
