dard piping connections may also be used in these positions.
Refer to Vent/Flue Pipe and Combustion Air Pipe for details con-
cerning the conversion to the alternate vent/flue and combus-
tion air connections.

ALTERNATE ELECTRICAL AND GAS LINE CONNECTIONS
This furnace has provisions allowing for electrical and gas line
connectios through either side panel. In horizontal applications
the connections can be made either through the “top”or “bot-
tom” of the furnace.
DRAIN PAN
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).
FREEZE PROTECTION
Refer to Horizontal Applications and Conditions - Drain Trap and
Lines.

This manual refers 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 is 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 prod-
ucts of combustion and cooling them to the point where con-
densation takes place. Because of the relatively low flue gas
temperature and water condensation requirements, PVC or
ABS are typical 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. Do not use com-
mercially available “no hub connectors” other than those
shipped with this product.
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.
