Individual Venting - ALLIANCE CA050L Installation Operation & Maintenance

Exhaust Requirements
pop-rivets on all seams and joints is recommended, if allowed by
local codes.
Verify that old ducts are thoroughly cleaned out before installing
new tumble dryer(s).
Improperly sized or assembled ductwork causes ex-
cess back pressure which results in slow drying, lint
collecting in the duct, lint blowing back into the
room, and increased fire hazard.

1. Removable strip of panel in framing wall to permit removal of tumble dryer from framing wall
2. Partition or bulkhead
3. Minimum distance between exhaust opening and roof, ground or other obstruction: 36 in. [914 mm]
4. 2 in. [51 mm] minimum clearance on both sides of duct
5. Exhaust airflow – maximum length of rigid duct 14 ft. [4.3 m] or 7.87 ft. [2.4 m] of flexible metal duct
NOTE: Do not install wire mesh or screen in exhaust
duct opening to avoid lint build-up or impacting proper
discharge of air from tumble dryers.
NOTE: Where exhaust duct pierces a combustible wall
or ceiling, the opening must be sized per local codes.
NOTE: Inside of duct must be smooth. Do not use
sheet metal screws to join sections.
NOTE: Locate exhaust far enough away from make-up
air location to prevent re-introduction.
Consult your local building code for regulations which may also
apply.

NOTE: Exhaust ducts must be constructed of sheet
metal or other noncombustible material. Such ducts
must be equivalent in strength and corrosion resist-
ance to ducts made of galvanized sheet steel not less
than 0.0195 inches [0.495 mm] thick.
Where the exhaust duct pierces a combustible wall or ceiling, the
opening must be sized per local codes. The space around the duct
may be sealed with noncombustible material. Refer to Figure 18 .
IMPORTANT: For best performance provide an individ-
ual exhaust duct for each tumble dryer. Do not install a
hot water heater in a room containing tumble dryers. It
is better to have the water heater in a separate room
with a separate air inlet.

Figure 18

Individual Venting

For maximum efficiency and performance, it is preferred to ex-
haust tumble dryer(s) individually to the outdoors.
IMPORTANT: At no point may the cross sectional area
of installed venting be less than the cross sectional
area of the exhaust outlet of the tumble dryer.
The exhaust duct must be designed so the static back pressure
measured 12 inches [305 mm] from the exhaust outlet does not
exceed the maximum allowable pressure specified in the Specifi-
cations and Dimensions Table or on the installation sticker on the
rear of the tumble dryer.
