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.
A E
LTERNATE LECTRICAL AND
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.
D P
RAIN AN
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).
F P
REEZE ROTECTION
Refer to Section VII, Horizontal Applications and Conditions - Drain
Trap and Lines.
F S
URNACE USPENSION
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 Requirements and Considerations - Furnace
Suspension for further details.

HE APPROPRIATE KITS
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).

PON COMPLETION OF THE FURNACE INSTALLATION, CAREFULLY INSPECT THE

IS PROPERLY SEALED.
PERSONAL INJURY OR DEATH DUE TO EXPOSURE TO FLUE PRODUCTS,
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.
It is the responsibility of the installer to follow the manufacturers'
TIO O O O O NS TI TI TI NS NS NS NS recommendations and to verify that all vent/flue piping and connec-
tors are compatible with furnace flue products. Additionally, it is the
responsibility of the installer to ensure that all piping and connec-
tions possess adequate structural integrity and support to prevent
flue pipe separation, shifting, or sagging during furnace operation.
