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
furnace operation. All conversions must be performed by a
qualified installer, or service agency.

WARNING
A condensing gas furnace achieves its high level of efficiency
by extracting almost all of the heat from the products of com-
bustion and cooling them to the point where condensation
takes place. Because of the relatively low flue gas tempera-
ture and water condensation requirements, PVC or ABS pipe
is typically used as venting material.
In addition to PVC and ABS pipe and fittings, Innoflue
®
by
Centrotherm Eco Systems and PolyPro
®
by M&G Duravent
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 built with 2" vent / intake pipe and con-
nectors. 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
integrity and support to prevent flue pipe separation, shift-
ing, or sagging during furnace operation.
