M Ethods; Canadian Venting Requirements; Standard Furnace Connections; Lternate Urnace Onnections - Goodman GKS9 Installation Instructions Manual

• A vent termination shall not terminate over public walkways
or over an area where condensate or vapor could create
a nuisance or hazard or could be detrimental to the
operation of regulators, relief valves, or other equipment.
• The combustion air intake termination of a direct vent
application should not terminate in an area which is
frequently dusty or dirty.

ANADIAN ENTING EQUIREMENTS
In Canada, venting must conform to the requirements of the cur-
rent CAN/CSA-B149.1-05 Installation Code. Use only CSA-listed,
ULC-S636 compliant two-three-inch diameter PVC or ABS pipe,
solvent cement, and fittings throughout. The certified piping should
be clearly marked with the ULC Std "S636" on the pipe and fittings.
Carefully follow the pipe manufacturers' instructions for cutting,
cleaning, and solvent cementing PVC and/or ABS.
The vent can be run through an existing unused chimney provided
the space between the vent pipe and the chimney is insulated and
closed with a weather-tight, corrosion-resistant flashing.

TANDARD URNACE ONNECTIONS
It is the responsibility of the installer to ensure that the piping
connections to the furnace are secure, airtight, and adequately
supported.
As shipped, attachment "couplings" for vent/flue and combustion
air intake pipe connections are provided on the furnace's top cover
(upflow). To use the standard connections, field supplied vent/flue
pipe and combustion air intake pipe (when applicable) should be
secured directly to the furnace at these locations.

Vent/flue pipe can be secured to the vent/flue coupling using the
rubber coupling and worm gear hose clamps provided with this
furnace (see "Standard Connections" figure). The rubber coupling
allows separation of the vent/flue pipe from the furnace during
servicing. Combustion Air and Vent piping should be routed in a
manner to avoid contact with refrigerant lines, metering devices,
condensate drain lines, etc. If necessary, clearances may be
increased by utilizing two 45 deg. Long-Sweep Elbows and creat-
ing an "S" joint to provide additional space at connection loca-
tions. This joint can be rotated on the fitting to establish maxi-
mum clearance between refrigerant lines, metering devices, and
condensate drain lines, etc. This joint is the equivalent of one 90
deg. elbow when considering elbow count.

NOTE: Do not use other commercially available "no hub connec-
tors" due to possible material conflicts. The vent/flue pipe can
also be secured using a PVC or ABS elbow or coupling using the
appropriate glue (see Section IX, Materials and Joining Methods.
NOTE: For non-direct vent installations, a minimum of one 90°
elbow should be installed on the combustion air intake coupling
to guard against inadvertent blockage.

LTERNATE URNACE
If the standard locations are undesirable for a specific installation,
alternate side panel locations are available for vent/flue pipe con-
nections. These locations may be of particular benefit to upright
upflow installations requiring additional access to an A coil or to
horizontal installations desiring vent/flue piping run vertically from
the side of the cabinet.
NOTE: Standard and alternate locations can be combined (i.e., an
installation may use the standard combustion air intake location
but use the alternate vent/flue location), if needed.
