This furnace has provisions allowing for electrical and gas line con-
nections through either side panel.  In horizontal applications the
connections can be made either through the “top” or “bottom” of
the furnace.

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).

Refer to Horizontal Applications and Conditions - Drain Trap and
Lines.

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 Location Requirements and Considerations - Furnace Suspen-
sion for further details.

This furnace is shipped from the factory configured for natural gas
at standard altitude.  Propane gas installations require an orifice
and orifice change to compensate for the energy content differ-
ence between natural and propane gas.

High altitude installations may require both a pressure switch and
an orifice/spring change.  These changes are necessary to com-
pensate 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-
tions.  The indicated kits must be used to insure safe and proper
furnace operation.  All conversions must be performed by a quali-
fied installer, or service agency.

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 fac-
tory 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
connectors” other than those shipped with this product.

It is the responsibility of the installer to follow the manufacturers’
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 con-
nections possess adequate structural integrity and support to pre-
vent flue pipe separation, shifting, or sagging during furnace opera-
tion.

This furnace is dual certified and may be installed as a non-direct
vent (single pipe) or direct vent (dual pipe) appliance.  A non-direct
vent installation requires only a vent/flue pipe, while a direct vent
installation requires both a vent/flue pipe and a combustion air
intake pipe.  Refer to the appropriate section for details concerning
piping size, length, number of elbows, furnace connections, and
terminations.
