L Ocation R Equirements & C Onsiderations - Amana xMVM97 series Installation Instructions Manual

ACCEPTABLE
Precautions should be taken to prevent condensate from freez-
ing inside the vent/flue pipe and/or at the vent/flue pipe termi-
nation. All vent/flue piping exposed to temperatures below 35°F
for extended periods of time must be insulated with 1/2" thick
closed cell foam. Also, all vent/flue piping exposed outdoors in
excess of the terminations shown in this manual (or in unheated
areas) must be insulated with 1/2" thick closed cell foam. In-
spect piping for leaks prior to installing insulation.

ERMINATION OCATIONS
NOTE: Refer to Location Requirements and Considerations
for combustion air contaminant restrictions.
The following bullets and diagram describe the restrictions
concerning the appropriate location of vent/flue pipe and com-
bustion air intake pipe (when applicable) terminations. Refer
to Non-Direct Vent (Single Pipe) Piping and Direct Vent (Dual
Pipe) Piping located in this section for specific details on ter-
mination construction.
• 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 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 running 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.
NOTE: In Canada, the current edition of CAN/CSA B149.1
takes precedence over the preceding termination restriction.

All installations in Canada must conform to the requirements
of CAN/CSA B149.1 code. All vent system components, in-
cluding primer and cement, must be listed to ULC S636. The
certified pipe and fittings should be clearly marked with the
ULC standard "S636". The primer and cement used must be
of the same manufacturer as the vent system. For Royal Pipe
System 636; use GVS-65 Primer (Purple) and GVS-65 PVC Sol-
vent Cement. For IPEX System 636, use PVC/CPVC Primer,
Purple or clear. Use PVC Solvent Cement (Gray).
For Canadian installations, ABS may be used as a combus-
tion air pipe only. ABS is not an approved vent material in
Canada. If ABS is used as a combustion air pipe, it must be
CSA certified. Always follow the manufacturer's instructions
in the use of primer and cement. Do not use primer and
cement around potential sources of ignition. Do not use primer
or cement beyond its expiration date.
The safe operation, as defined by ULC S636, of the vent
system is based on following these installation instructions,
the vent system manufacturer's installation instructions, and
proper use of primer and cement. It is recommended under
this standard, that the vent system be checked once a year
by qualified service personnel. All fire stops and roof flashings
used with this system must be UL listed. Acceptability under
CAN/CSA B149.1 is dependent upon full compliance with all
installation instructions. Consult the authority having juris-
diction (gas inspection authority, municipal building depart-
ment, fire department, etc.) before installation to deter-
mine the need to obtain a permit. *IPEX System 636™ is a
trademark of IPEX Inc.
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 pro-
vided the space between the vent pipe and the chimney is insu-
lated and closed with a weather-tight, corrosion-resistant flash-
ing.
