B. LOCATION OF THE DRYER
Before installing the dryer, be sure the location conforms to local codes and ordinances. In the absence of such
codes or ordinances the location must conform with the National Fuel Gas Code ANSI.Z223.1 LATEST
EDITION, or in Canada, the installation mustconform to applicable Canadian Standards: CAN/CGA-B149.1-
M91 (Natural Gas) or CAN/CGA-B149.2-M91 (Liquid Propane [L.P.] Gas) or LATEST EDITION (for General
Installation and Gas Plumbing).
1. The dryer must be installed on a sound level floor capable of supporting its weight. Carpeting must be
removed from the floor area that the dryer is to rest on.
IMPORTANT: “Thedryer mustbeinstalledonnoncombustiblefloorsonly.”
2. Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be
positioned approximately 2 feet (0.61 meters) away from the nearest obstruction, i.e., wall, for ease of
installation, maintenance, and service.
3. The dryer must be installed with a proper exhaust duct connection to the outside.
4. The dryer must be installed with provisions for adequate combustion and make-up air supply.
CAUTION: Thisdryerproduces combustible lint andmustbeexhaustedto the outdoors. Every
6months,inspecttheexhaustductingandremoveanylintbuildup.
IMPORTANT: Dryer must be installed in a location/environment, which the ambient
temperatureremainsbetween 40º F (4.44ºC)and 130º F (54.44ºC).
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible materials and must be located a minimum of
24-inches (60.96 cm) above the dryer outer top, except along the front of the dryer which may be closed in if
desired.

9
D. FRESH AIR SUPPLYREQUIREMENTS
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. An
unrestricted source of 1,040 cfm (29.44 cmm) is necessary for each dryer (total for both baskets [tumblers]).
An unrestricted air entrance from the outdoors (atmosphere) of a minimum of 1-1/2 square feet (0.14 square
meters) is required for each dryer. This area must be enlarged if louvers or registers cover the opening. 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 the
dryers. For example, for a bank of eight (8) dryers, a total make-up air opening of 12 square feet
(1.15 square meters) is required. Two (2) openings measuring 2 feet by 3 feet (0.61 meters by 0.91 meters)
(6 square feet [0.58 square meters]) are acceptable. The dryer must be installed with provisions for adequate
combustion and make-up air supply.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive
altitudes or predominantly low-pressure areas.
IMPORTANT: Make-upairmustbe provided from asourcefreeof dry cleaning solventfumes.

NOTE: ComponentfailureduetodrycleaningfumeswillVOIDTHEWARRANTY.

10
E. EXHAUST REQUIREMENTS
Exhaust ductwork shouldbedesigned and installed by a qualified professional. Improperly sized ductwork will
create excessive back pressure which will result in slow drying, increased use of energy, overheating of the
dryer, and shutdown of the burner by 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.
CAUTION: Thisdryerproduces combustible lint andmustbeexhausted to theoutdoors.
When possible, it is suggested to provide a separate exhaust duct for each dryer.
CAUTION: IMPROPERLYSIZEDOR INSTALLEDEXHAUSTDUCTWORK CAN
CREATEAPOTENTIALFIREHAZARD.
The exhaust ductwork must be laid out in such a way that the ductwork travels as directly as possible to the
outdoors with as few turns as possible. The shape of the ductwork is not critical provided that the minimum
cross-sectional area is maintained.
When single dryer venting is used, for horizontal or vertical venting the minimum duct size is 10-inches
(25.40 cm) in diameter and the ductwork from the dryer to the outside exhaust outlet must not exceed a
distance of 35 feet (10.67 meters) and have no more than two (2) elbows (including both connection to dryer and
outside protection).
In the case of multiple (common) venting, using the applicable duct size (diameter) noted in this manual, for
horizontal venting the distance from the last dryer to the outside outlet must not exceed 15 feet (4.57 meters)
and have no more than one (1) elbow (including outside protection). In the case of common vertical venting, the
distance from the last dryer to the outside outlet must not exceed 25 feet (7.62 meters) and have no more than
three (3) elbows (including outside protection).
IMPORTANT: Exhaust back pressure measuredby a manometer at thedryer exhaust duct area must
beno less than 0 and mustnotexceed 0.3 inches (0.74 mb) of water column
(W.C.).
It is suggested that the use of 90º turns in ducting be avoided; use 30º or 45º angles instead. The ductwork
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. Also, inspection
doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.
When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the opening
must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be centered within this
opening.
If the ductwork run (distance) or the amount of elbows required exceeds the limits noted in this manual, the size
(diameter/cross-sectional area) of the ductwork must be increased in proportion to the length or number of
elbows added. When the ductwork approaches the maximum limits as noted in this manual, a professional
heating, ventilating, and air-conditioning (HVAC) firm must be consulted for proper venting information.
1. Dryer exhaust connection. The dryer is shipped with a 10-inch (25.40 cm) exhaust adapter, which for
shipping purposes is shipped inside of the dryer’s basket (tumbler). This exhaust adapter must beinstalled
(with screws provided) once the dryer is in place prior to making any exhaust connections.

2. Venting Layout
a. Single DryerVenting
When single dryer venting is used, for horizontal or vertical venting the minimum duct size is 10-inches
(25.40 cm) in diameter and the ductwork from the dryer to the outside exhaust outlet must not exceed
a distance and the number of elbows (including both connection to dryer and outside protection shown
in the illustration below).
IMPORTANT: Exhaustbackpressuremeasuredbya manometer at the dryer exhaust duct area must
beno less than 0 and mustnotexceed 0.3 inches (0.74 mb) of water column
(W.C.).

b. CommonVenting
If it is not feasible to provide separate exhaust ducts 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 common duct at an angle not more than 45º in the direction of airflow. The main duct should be
tapered, with the diameter increasing before each individual duct 10-inches (25.40 cm) is added.
IMPORTANT: No more than four (4) dryers or eight (8) pockets total shouldbeconnected to one
(1)common duct.
Minimum duct size between dryer and common duct is 10-inches (25.40 cm) in diameter. This duct
must not travel more than 15 feet (4.57 meters) and include no more than three (3) elbows (which
includes both dryer and common duct connections).
NOTE: Refertoillustrationson page13andpage14forexamplesof multiple dryer (common)
venting.
In the case of multiple (common) venting, using the applicable duct size (diameter) noted in this manual,
for horizontal venting the distance from the last dryer to the outside outlet must not exceed 15 feet
(4.57 meters) and have no more than one (1) elbow (including outside protection). In the case of
common vertical venting, the distance from the last dryer to the outside outlet must not exceed 25 feet
(7.62 meters) and have no more than three (3) elbows (including outside protection).

firmmustbeconsulted forproper ventinginformation.

14
c. Outside Ductwork (Vent) Protection
To protect the outside end of the horizontal ductwork from the weather, a 90º elbow turned downward
should be installed where the exhaust duct exits the building. If the ductwork travels vertically up
through a roof, it should be protected from the weather by using a 180º turn (goose neck) 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,orcapsontheoutsideopeningoftheexhaust
ductwork.

15
When the exhaust ductwork passes through a wall, ceiling, or roof made of combustible materials, the
opening must be 2-inches (5.08 cm) larger than the duct (all the way around). The duct must be
centered within this opening.
