Combustion; Non; Ipe; Irect - Goodman GMSS96 Installation Instructions Manual

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
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 installa-
tions. The indicated kits must be used to insure safe and proper
furnace operation. All conversions must be performed by a quali-
fied installer, or service agency.

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.
In addition to PVC and ABS pipe and fittings, Innoflue
Centrotherm Eco Systems and PolyPro
also approved vent and combustion air materials for installa-
tions in the U.S.A. and Canada. Manufacturers Installation
instructions for these products must be followed. These prod-
ucts have specific instructions for installing, joining and ter-
minating. Do not mix materials or components of one manu-
facturer with materials or components of another manufac-
turer.
All furnaces are built with 2" vent / intake pipe and connec-
tors. For furnaces requiring installation of 3" pipe, the tran-
sition 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 manufacturers' 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 separation, shifting, or sagging during furnace
operation.

UAL ERTIFICATION ON
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.

ATERIALS AND OINING
Two-three-inch nominal diameter PVC Schedule 40 pipe meet-
ing 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 manufacturer's instruc-
tions for cutting, cleaning, and solvent cementing of PVC.
