ALTERNATE VENT/FLUE AND COMBUSTION AIR
CONNECTIONS
In horizontal installations provisions for alternate flue and
combustion air piping are available for upflow furnaces
with left discharge and counterflow furnaces with right air
discharge. In these positions the flue and combustion air
piping can 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 Section IX, Vent/
Flue Pipe and Combustion Air Pipe for details concerning
the conversion to the alternate vent/flue and combustion
air connections.

Recommended Installation Positions
NOTE: Alternate “vertical” piping connections can not be
used when an upflow furnace is installed with supply air
discharging to the right, or when a counterflow furnace is
installed with supply air discharging to the left. In either
case, use the standard flue and combustion air piping
connections.
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 Section VI, 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. Never install the furnace on the ground or allow it to
be exposed to water. Refer to Section IV, Location Re-
quirements and Considerations - Furnace Suspension for
further details.
VIII. Propane Gas and/or High
Altitude Installations
WARNING
Possible death, personal injury or property
damage may occur if the correct conversion
kits are not installed. The appropriate kits
must be applied to insure safe and proper
furnace operation. All conversions must
be performed by a qualified installer or
service agency.
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 change. These changes are neces-
sary to compensate for the natural reduction in the density
of both the gas fuel and the combustion air at higher
altitude.
Refer to the product Specification Sheet or contact an
Amana distributor for a tabular listing of appropriate
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.
