Canadian Venting Requirements; Standard Furnace Connections; Alternate Furnace Connections - Amana AMV9 Installation Instructions Manual

• All terminations (flue and/or intake) must be located at
least 12 inches above ground level or the anticipated
snow level.
• Vent terminations (non-direct and direct vent) must
terminate at least 3 feet above any forced air inlet located
within 10 feet.
NOTE: This provision does not apply to the
combustion air intake termination of a direct vent
application.
• The vent termination of a non-direct vent application must
terminate at least 4 feet below, 4 feet horizontally from, or
1 foot above any door, window, or gravity air inlet into any
building.
• The vent termination of a direct vent application must
terminate at least 12 inches from any opening through
which flue gases may enter a building (door, window, or
gravity air inlet).
• The vent termination of vent pipe run vertically through a
roof must terminate at least 12 inches above the roof line
(or the anticipated snow level) and be at least 12 inches
from any vertical wall (including any anticipated snow build
up).
• 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 current
CAN/CSA-B149 Installation Code. Use only CSA listed two or three
inch diameter PVC or ABS pipe, solvent cement, and fittings through-
out. Carefully follow the manufacturers' instructions for cutting, clean-
ing, 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

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) or basepan (counterflow). To use the standard connec-
tions, field supplied vent/flue pipe and combustion air intake pipe
(when applicable) should be secured directly to the furnace at these
locations.

ENT LUE IPE
Vent/flue pipe can be secured to the vent/flue coupling using the
rubber coupling and worm gear hose clamps provided with this fur-
nace (see "Standard Connections" figure). The rubber coupling al-
lows separation of the vent/flue pipe from the furnace during servic-
ing. NOTE: Do not use other commercially available "no hub con-
nectors" 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.

IRECT ENT NSTALLATIONS
On upflow units secure the combustion air intake pipe directly to the
air intake coupling. On counterflow units secure the combustion air
intake pipe to the air intake coupling using the rubber coupling and
worm gear hose clamps provided with the unit. The counterflow rub-
ber coupling allows service removal of air intake piping internal to
the furnace blower compartment. NOTE: Because of probable ma-
terial conflicts, do not use other commercially available "no hub con-
nectors". The combustion air intake pipe can also be secured di-
rectly to the counterflow unit air intake pipe coupling.
