Exhaust ducts shall be constructed of sheet metal
or other noncombustible material. Such ducts must
be equivalent in strength and corrosion resistance
to ducts made of galvanized sheet steel not less than
0.0195 inch (0.495 mm) thick.
Where the exhaust duct pierces a combustible wall
or ceiling, provide an opening with a diameter 4 inches
(102 mm) larger than the diameter of the exhaust duct.
Center duct in the opening. When ducts pass through
walls, ceilings, floors or partitions, the space around
the duct shall be sealed with noncombustible material.
Refer to Figure 12.
NOTE: FOR BEST PERFORMANCE, provide
an individual exhaust duct for each tumbler. Do not
install a hot water heater in a room containing
tumblers. It is better to have the water heater in a
separate room with a separate air inlet.
Alternate Venting for 120 Pound Tumblers
The 120 pound tumbler is equipped from the factory
to exhaust from the top; however, it may be converted
to exhaust out the rear by doing the following (refer to
Specifications and Dimensions):
1. Remove belt guard cover.
2. Remove 10 inch diameter elbow and vertical
duct.
3. Cut out shape from belt guard cover. Refer to
Figure 8.
4. Screw octagonal piece over 10 inch diameter
opening in top of belt guard.
5. Attach new exhaust duct to exhaust thimble on
rear panel, following all requirements in this
section.
6. Replace belt guard cover, sliding cut-out section
around duct.
Figure 8
Improperly sized or assembled ductwork
causes excess back pressure which
results in slow drying, lint collecting in the
duct, lint blowing back into the room, and
increased fire hazard.
