Installation of this furnace at altitudes above 7000 ft (2134 m)
shall be made in accordance with the Listed High Altitude
Conversion Kit available with this furnace.”
L'installation de ce générateur de chaleur à des altitudes
supérieures à 7000 pi (2134 m) doit être effectuée
conformément aux instructions accompagnant la trousse de
conversion pour haute altitude fournie avec cet appareil.
For installations above 7000 feet, please refer to the furnace
Specification Sheets for required kit(s).
Contact the distributor for a tabular listing of appropriate
manufacturer’s kits for propane gas and/or high altitude
installations. The indicated kits must be used to insure
safe and proper furnace operation. All conversions must
be performed by a qualified installer, or service agency.

WARNING
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
furnace will be referred to as the “intake” pipe or “com-
bustion air” pipe.
A condensing gas furnace achieves its high level of efficiency by
extracting almost all of the heat from the products of combus-
tion 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 are typically
used as venting and intake pipe materials. In Canada, ABS
is not an approved vent pipe material but it is permissible
to use as combustion air pipe 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 instal-
lations in the U.S.A. and Canada. Manufacturers Installation
instructions for these products must be followed. These
products have specific instructions for installing, joining
and terminating. Do not mix materials or components 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 commercially available “no hub connectors” other
than those shipped with this product.
It is the responsibility of the installer to follow the man-
ufacturers’ recommendations and to verify that all vent/
flue piping 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 sepa -
ration, shifting, or sagging during furnace operation.
Dual Certification: Non-Direct/Direct Vent
This furnace is dual certified and may be installed as a non-di -
rect 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 ap-
propriate section for details concerning piping size, length,
number of elbows, furnace connections, and terminations.

WARNING
Two-three-inch nominal diameter PVC Schedule 40 pipe
meeting ASTM D1785, PVC primer meeting ASTM F656, and
PVC solvent cement meeting ASTM D2564 specifications
must be used. Fittings must be DWV type fittings meeting
ASTM D2665 and ASTM D3311. Carefully follow the man-
ufacturer’s instructions for cutting, cleaning, and solvent
cementing of PVC.
The use of Schedule 40 PVC cellular core DWV meeting
ASTM F891-1 or ABS cellular core (Foam Core) plastic pipe
is also acceptable as a flue/vent and intake pipe material.
