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 the furnace Speci-
fication Sheets for required kit(s).

WARNING
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.
