Bulkheads and partitions must be made of noncombustible materials and must be located a minimum of
12-inches (30.48 cm) above the dryer outer top, except along the front of the dryer which may be partially closed
in if desired. It is suggested that the dryer be positioned about 2 feet (0.61 meters) away from the nearest
obstruction, for ease of installation, maintenance, and service (to be measured from the back guard).
NOTE: Allowancesmustbe madefor opening thecontroldoor.
Dryers may be positioned sidewall to sidewall. However, a 1/16” (1.5875 mm) minimum allowance must be
made for the opening and closing of the control door. Refer to the illustration below for details.
NOTE: Airconsiderationsareimportantforproperandefficientoperation.

Make-upair thatiscontaminatedbydrycleaningsolvent fumeswillresultin
irreparabledamageto themotorsand other dryercomponents.
NOTE: Componentfailure due todrycleaningsolventfumeswillVOIDTHEWARRANTY.
D. FRESH AIR SUPPLYREQUIREMENTS
This appliance may only be installed in a room that meets the appropriate ventilation requirements specified in
the national installation regulations.
When the dryer is operating, it draws in room air, heats it, passes this air through the basket (tumbler), and
exhausts it out of the building. Therefore, the room air must becontinually replenished from the outdoors. If the
make-up air is inadequate, drying time and drying efficiency will be adversely affected. Ignition problems and
sail switch “fluttering” problems may result, as well as premature motor failure from overheating.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of 800 cfm (22.66 cmm) is necessary for each dryer. As a general rule, an unrestricted air
entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.41 square meters) is required for
each dryer. The area must be enlarged if louvers or registers cover the openings. The dryer must be installed
with provisions for adequate combustion and make-up air supply.
To compensate for the use of registers or louvers used over the openings, this make-up air must be increased by
approximately thirty-three percent (33%). Make-up air openings should not be located in an area directly near
where exhaust vents exit the building.
It is not necessary to have a separate make-up air opening for each dryer. Common make-up air openings are
acceptable. However, they must be set up in such a manner that the make-up air is distributed equally to ALL
the dryers.
A = 18” (45.72 cm)
B = 24” (60.96 cm)

113215- 12 www.adclaundry.com 11
E. EXHAUST REQUIREMENTS
Exhaust ductwork shouldbe designed and installed by a qualified professional. Improperly sized ductwork will
create excessive back pressure which results in slow drying, increased use of energy, overheating of the dryer,
andshut down of the burnerby the airflow (sail) switches,burner hi-limits, or basket (tumbler)hi-limit thermostats.
The dryer must be installed with a proper exhaust duct connection to the outside.
The design of the flue system shall be such that any condensate formed when operating the appliance from cold
shall either be retained and subsequently re-evaporated or discharged.
CAUTION: Thisdryerproduces combustiblelintand mustbeexhaustedto the outdoors.
CAUTION: IMPROPERLYSIZEDORINSTALLEDEXHAUSTDUCTWORKCAN
CREATEAPOTENTIALFIREHAZARD.
The ductwork should be laid out in such a way that the ductwork travels as directly as possible to the outdoors
with as few turns as possible.
1. Single Dryer Venting
Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust ductwork
should be laid out in such a way that the ductwork travels as directly as possible to the outdoors with as
few turns as possible. It is suggested that the use of 90° turns be avoided; use 30° and/or 45° bends
instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. The shape
of the ductwork is not critical as long as the minimum cross-sectional area is provided.
IMPORTANT: Exhaustbackpressuremeasuredbyamanometer/magnehelicintheexhaustduct
mustbe no less than 0 and must not exceed0.3 in WC (0.74 mb) with both baskets
(tumblers)operating.
NOTE: Itis recommendedthat exhaust orbooster fans notbe used inthe exhaustductworksystem
exceptwherenecessary to maintain exhaustbackpressure (in the exhaustduct)between zero
and0.3inch water columnwithbothbaskets (tumblers) operating. Whereemployed,booster
fansmustnotactivatethedryerairflow proving switch (sail switch)when thedryer isnotin
operation.
It is suggested that the ductwork from each dryer must not exceed 20 feet (6.1 meters) with no more than
two (2) elbows. If the ductwork exceeds 20 feet (6.1 meters) or has numerous elbows, the cross-sectional
area of the ductwork must be increased in proportion to the length or number of elbows in it.
IMPORTANT: Forextended ductwork runs,the cross-sectionalarea of theductwork canonly be
increasedtoanextent. When the ductwork approachesthemaximumlimitsas noted
inthismanual,aprofessionalheating,ventilating,andair-conditioning(HVAC)firm
shouldbeconsultedforproperventinginformation.
NOTE: Asper the NationalFuel Gas Code,“Exhaust ductsforType2clothes dryers shallbe
constructedofsheetmetalorothernoncombustiblematerial. Suchductsshallbeequivalentin
strengthandcorrosionresistance to ducts madeofgalvanizedsheetsteel not less than
0.0195inches(26 gauge [0.5mm])thick.”

12 American Dryer Corp. 113215 - 12
ALLductwork should be smooth inside with no projections from sheet metal screws or other obstructions,
which will collect lint. When adding ducts, the duct to be added should overlap the duct to which it is to be
connected. ALL ductwork joints must be taped to prevent moisture and lint from escaping into the
building. Inspection doors should be installed at strategic points in the exhaust ductwork for periodic
inspection and cleaning of lint from the ductwork.
NOTE: Whentheexhaustductworkpassesthrougha wall, ceiling, orroof madeof combustible
materials,theopening mustbe2-inches(5.08 cm) largerthanthe duct (allthewayaround).
Theductmustbecentered withinthis opening.
Outside Ductwork Protection
To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should
be installed where the exhaust exits the building. If the ductwork travels vertically up through the roof, it
should be protected from the weather by using a 180° turn to point the opening downward. In either case,
allow at least twice the diameter of the duct between the duct opening and the nearest obstruction.
IMPORTANT: DONOTusescreens, louvers, or caps onthe outsideopening ofthe exhaust
ductwork.
2. Multiple Dryer (Common) Venting
If it is not feasible to provide a separate exhaust duct for each dryer, ducts from individual dryers may be
channeled into a “common main duct.” The individual ducts should enter the bottom or the side of the main
duct at an angle not more than 45° in the direction of the airflow. The main duct should be tapered with
the diameter increasing before each individual 8-inch (20.32 cm) duct is added.
IMPORTANT: Nomore thaneight (8)dryers should beconnected toone (1)main common duct
(refertotheillustrationonthefollowingpage).
The main duct may be any shape as long as the minimum cross-sectional area is provided. The illustration
on the following page shows the minimum cross-sectional area for multiple dryer venting. These figures
must be increased in proportion as the result of whatever changes or additions are made to this ductwork
run. Two examples are if ductwork length from last dryer to where duct exits the building exceeds limits
noted (20 feet [6.1 meters]) or, if ductwork runs from last dryer to where duct exits the building has more
than one (1) elbow (including outside protection).

To protect the outside end of the horizontal ductwork from the weather, a 90° elbow bent downward should
be installed where the exhaust exits the building. If the exhaust ductwork travels vertically up through the
roof, it shouldbe protected from the weather by using a 180° turn to point the opening downward. In either
case, allow at least twice the diameter of the duct between the duct opening and nearest obstruction.

3. Grounding
A ground (earth) connection must be provided and installed in accordance with state and local codes. In
the absence of these codes, grounding must conform to applicable requirements of the National Electrical
CodeANSI/NFPANO. 70-LATEST EDITION, or in Canada, the installation must conform to applicable
Canada Standards: Canadian Electrical Codes Parts 1 & 2 CSA C22.1-1990 or LATEST EDITION. The
ground connection may be to a proven earth ground at the location service panel.
For added personal safety, when possible, it is suggested that a separate ground wire (sized per local codes)
be connected from the ground connection of the dryer to a grounded cold water pipe. DO NOT ground to
a gas pipe or hot water pipe. The grounded cold water pipe must have metal-to-metal connection ALL
the way to the electrical ground. If there are any nonmetallic interruptions, such as, a meter, pump, plastic,
rubber, or other insulating connectors, they must be jumped out with no. 4 copper wire and securely
clamped to bare metal at both ends.
IMPORTANT: Forpersonal safetyand properoperation, thedryer must be grounded.
Provisions are made for ground connection in each dryer at the electrical service connection area.
