This furnace has provisions allowing for electrical and gas
line connections through either side panel. In horizontal ap-
plications 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).

This furnace is shipped from the factory configured for natu-
ral gas up to 10,000 ft. altitude. Propane conversions re-
quire the proper LP kit to compensate for the energy con-
tent difference between natural and propane gas.

N O T E : In Canada, gas furnaces are o nly certified to 4500 feet.
For furnaces being converted to LP gas, it is strongly rec-
ommended that a LPLP03 kit also be installed. The use of
this kit will prevent the furnace from firing when the LP
gas supply pressure is too low to support proper combus-
tion.
The indicated kit must be used to ensure safe and proper fur-
nace operation. All conversions must be performed by a quali-
fied installer, or service agency.

This manual will refer to the pipe that discharges products
of combustion to the outdoors as the “vent” pipe or “flue”
pipe. The pipe that supplies air for combustion to the fur-
nace will be referred to as the “intake” pipe or “combustion
air” pipe. 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 condensation requirements, PVC or ABS pipe is typi-
cally used as venting and intake pipe materials. In Canada
ABS is not an approved vent pipe material but it is permissable
to use as combustion air pipe material.
In addition to PVC and ABS pipe and fittings, Innoflue

are also approved vent and combustion air materials for
installations in the U.S.A. and Canada. Manufacturers In-
stallation instructions for these products must be followed.
These products have specific instructions for installing,
joining and terminating. Do not mix materials or compo-
nents of one manufacturer with materials or components
of another manufacturer.
All furnaces are manufactured with 2" vent / intake pipe and
connectors. For furnaces requiring installation of 3" pipe,
the transition from 2" to 3" should be done as close to the
furnace as practically possible.
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.
It is the responsibility of the installer to follow the manufac-
turers’ recommendations and to verify that all vent/flue pip-
ing and connectors are compatible with furnace flue products.
Additionally, it is the responsibility of the installer to ensure
that all piping and connections possess adequate structural in-
tegrity and support to prevent flue pipe separation, shifting, or
sagging during furnace operation.

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 com-
bustion air intake pipe. Refer to the appropriate section for
details concerning piping size, length, number of elbows, fur-
nace connections, and terminations.
