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. Use the standard flue and combustion air piping 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.

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

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 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 your distributor
for required kit(s).

Contact the distributor for a tabular listing of appropriate
manufacturer's kits for propane gas and/or high altitude installa-

furnace operation. All conversions must be performed by a quali-
fied installer, or service agency.

INCLUDING CARBON MONOXIDE.
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 takes place.
Because of the relatively low flue gas temperature and water con-
densation requirements, PVC pipe is used as venting material.
This furnace must not be connected to Type B, BW, or L vent or vent
connector, and must not be vented into any portion of a factory built
or masonry chimney except when used as a pathway for PVC as
described later in this section. Never common vent this appliance
with another appliance or use a vent which is used by a solid fuel
appliance. Do not use commercially available "no hub connec-
tors" other than those shipped with this product.
