Amana xMVM97 series Installation Instructions Manual page 14

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.
It is the responsibility of the installer to follow the manufactur-
ers' recommendations and to verify that all vent/flue piping and
connectors are compatible with furnace flue products. Addition-
ally, it is the responsibility of the installer to ensure that all piping
and connections possess adequate structural integrity and sup-
port 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 com-
bustion air intake pipe. Refer to the appropriate section for
details concerning piping size, length, number of elbows, fur-
nace connections, and terminations.

ATERIALS AND OINING
Two- or three-inch nominal diameter PVC Schedule 40 pipe meet-
ing ASTM D1785, PVC primer meeting ASTM F656, and PVC sol-
vent cement meeting ASTM D2564 specifications must be used.
Fittings must be DWV type fittings meeting ASTM D2665 and
ASTM D3311. Carefully follow the pipe manufacturer's instruc-
tions for cutting, cleaning, and solvent cementing of PVC.
The use of Schedule 40 PVC or ABS cellular core (Foam Core)
plastic pipe is also acceptable as a flue/vent and intake pipe
material. PVC primer meeting ASTM F656 and PVC solvent ce-
ment meeting ASTM D2564 specifications must be used. Fittings
must be DWV type fittings meeting ASTM D2665 and ASTM D3311.
Carefully follow the manufactures instructions for cutting, clean-
ing and solvent cementing of PVC.
For Canadian installations; all PVC pipe, fittings and join-
ing materials must be UL S636 listed.
As an alternative to PVC pipe, primer, solvent cement, and
fittings, ABS materials which are in compliance with the
following specifications may be used: Two-or-three-inch solid
wall ABS Schedule 40 pipe must meet ASTM D1527 and, if
used in Canada, must be CSA listed or, two-or-three-inch
cellular core ABS Schedule 40 pipe must meet ASTM F628

and, if used in Canada, must be CSA listed. Solvent cement
for ABS to ABS joints must meet ASTM D2235 and, if used in
Canada, must be CSA listed. The solvent cement for the
PVC to ABS transition joint must meet ASTM D3138. Fittings
must be DWV type fittings meeting ASTM D2661 and ASTM
D3311 and, if used in Canada, must be CSA listed. Carefully
follow the manufacturers' instructions for cutting, clean-
ing, and solvent cementing PVC and/or ABS.
All 90° elbows must be medium radius (1/4 bend DWV) or long
radius (Long sweep 1/4 bend DWV) types conforming to ASTM
D3311. A medium radius (1/4 bend DWV) elbow measures 3 1/
16" minimum from the plane of one opening to the centerline of
the other opening for 2" diameter pipe, and 4 9/16" minimum
for 3" pipe.
The use of two short radius 45 degree elbows is permitted to
provide clearance to refrigerant piping above the furnace.

Adhere to these instructions to ensure safe and proper furnace
performance. The length, diameter, and number of elbows of the
vent/flue pipe and combustion air pipe (when applicable) affects
the performance of the furnace and must be carefully sized. All
piping must be installed in accordance with local codes and these
instructions.
Piping must be adequately secured and supported to prohibit
,
OPEN
sagging, joint separation, and/or detachment from the furnace.
.
Horizontal runs of vent/flue and combustion air piping must be
/
OR
properly supported. PVC pipe supports must be no more than
5' apart. For ABS pipe, supports must be no more than 3'
apart. Horizontal pipe runs must maintain a 1/4 inch per foot
downward slope, back towards the furnace, to properly return
condensate to the furnace's drain system.
