CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6
months, inspect the exhaust ducting and remove any lint buildup.
IMPORTANT: Dryer must be installed in a location/environment, which the ambient
temperature remains between 40° F (4.44° C) and 130° F (54.44° C).

113161-14 01422 822282 9
C. DRYER ENCLOSURE REQUIREMENTS
Bulkheads and partitions should be made of noncombustible material.
NOTE: Allowances must be made for opening the control door.
A30-inches (76.2 cm) for optimum opening of load door.
BThe maximum thickness of the bulkhead is 4-inches (10.16 cm). For electric dryers the maximum thickness of
the bulkhead is 1-inch (2.54 cm) within 3-inches (7.62 cm) from the top of the control door.
CFor gas and electric dryers a minimum overhead clearance of 12-inches (30.48 cm) is required, providing no
sprinkler is located above the dryer. For steam dryers or if a sprinkler is located above the dryer,
18-inches (45.72 cm) is required.
DDryer should be positioned 12-inches (30.48 cm) away from the nearest obstruction and 24-inches (60.96 cm)
is recommended for ease of installation, maintenance, and service.
E2-inch (5.08 cm) minimum is required for opening the control door.
FFlooring should be level or below dryer cabinet for ease of removing panels during maintenance.
GDryers 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, along with the removal of panels during maintenance.

10 JLA Limited 113161-14
EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 12-inches by 16-inches (30.5 cm by 40.64
cm) are acceptable.
Allowances must be made for remote or constricting passageways or where dryers are located at excessive altitudes
or predominantly low pressure areas.
IMPORTANT: Make-up air must be provided from a source free of dry cleaning solvent fumes.
Make-up air that is contaminated by dry cleaning solvent fumes will result in
irreparable damage to the motors and other dryer components.
NOTE: Component failure due to dry cleaning solvent fumes will VOID THE WARRANTY.
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 tumbler, and exhausts it out of
the building. Therefore, the room air must be continually 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. The dryer must be installed with provisions
for adequate combustion and make-up air supply.
Air supply (make-up air) must be given careful consideration to ensure proper performance of each dryer. As a
general rule, an unrestricted air entrance from the outdoors (atmosphere) measuring a minimum size of 8-inches by
12-inches (20.32 cm by 30.5 cm) is required for each dryer. (Based on 1 square inch per 1,000 Btu.)
To compensate for the use of registers or louvers used over the openings, this area 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 = 12-inches (30.5 cm)
B = 16-inches (40.64 cm)

113161-14 01422 822282 11
E. EXHAUST REQUIREMENTS
Exhaust ductwork should be designed and installed by a qualified professional. Improperly sized ductwork will
create excessive back pressure, which results in slow drying, increased use of energy, and shutdown of the burner
by the airflow (sail) switch, burner hi-limit, or lint chamber hi-heat protector thermostat. 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: This dryer produces combustible lint and must be exhausted to the outdoors.
Where possible, it is suggested to provide a separate (single) exhaust duct for each dryer.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN
CREATE APOTENTIAL FIRE HAZARD.
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. The shape of the ductwork is not critical as long as the minimum cross
section area is provided. Single or independent dryer venting is recommended.
It is suggested that the use of 90° turns be avoided; use 30° or 45° 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 ducts to be added should overlap the duct to which it is connected. ALL
ductwork joints must be taped to prevent moisture and lint from escaping into the building. Additionally, inspection
doors should be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning.
NOTE: 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.
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 (i.e., roof or ground level).
IMPORTANT: DO NOT use screens, louvers, or caps on the outside opening of the exhaust
ductwork.
IMPORTANT: Exhaust back pressure measured by a manometer at the dryer exhaust duct area must
be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).
IMPORTANT: It is recommended that exhaust or booster fans not be used in the exhaust ductwork
system.
NOTE: As per the National Fuel Gas Code, “Exhaust ducts for Type 2 clothes dryers shall be
constructed of sheet metal or other noncombustible material. Such ducts shall be equivalent
in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 26
gauge (0.0195-inches [0.5 mm]) thick.”

12 JLA Limited 113161-14
SINGLE DRYER VENTING
HORIZONTAL VENTING
When horizontal single 8-inch (20.32 cm) venting is used, the ductwork to the outlet cannot exceed 30 feet (9.14
meters), refer to Illus. A below. This calculation of 30 feet (9.14 meters) compensates or allows for the use of a
maximum of only one (1) elbow.
Illus. A

113161-14 01422 822282 13
VERTICAL VENTING
When vertical single venting is used, the minimum duct size is 10-inches (25.4 cm) refer to Illus. B below, the
ductwork from the dryer to the outside outlet cannot exceed 60 feet (18.29 meters), refer to Illus. B below. This
calculation compensates for the use of a maximum of three (3) elbows including the two (2) elbows creating the
180° (turned downward) outside outlet.
Illus. B
If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section area
of the ductwork must be increased in proportion to the number of elbows or duct run added.
IMPORTANT:For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. For extended ductwork runs, a professional heating, ventilating, and
air-conditioning (HVAC) firm should be consulted for proper venting information.

14 JLA Limited 113161-14
MULTIPLE DRYER (COMMON) VENTING
HORIZONTAL VENTING
If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled
into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the
bottom or side of the main duct at an angle not more than 45° in the direction of the airflow. No more than four (4)
dryers should be connected to one (1) main common duct run.
The main common duct may be any shape as long as the minimum cross-sectional area is provided. The main duct
should be tapered with the diameter increasing before each individual 8-inch (20.32 cm) duct is added (refer to
Illus. C and Illus. D).
Illus. C
Multiple Dryer Venting (Horizontal)
With 8-inch (20.32 cm) Diameter Exhaust Connections at Common Duct
Horizontal venting must not exceed 40 feet (12.2 meters) – this calculation compensates for the use of a maximum
of only one (1) elbow, which is the outside outlet protection.
NOTE: Ductwork should be laid out in such a manner where allowances are made at rear area of the
dryer for removal of rear service panels or guards.
Illus. Cshows the minimum cross section area for horizontal multiple dryer venting. These figures must be
increased in proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is
unusually long.

113161-14 01422 822282 15
IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. For extended ductwork runs, a professional heating, ventilating, and
air-conditioning (HVAC) firm should be consulted for proper venting information.
VERTICAL VENTING
Illus. D
Vertical venting must not exceed 25 feet (7.62 meters) – this calculation compensates for the use of a maximum of
three (3) elbows including the two (2) elbows creating the 180º (turned downward) outside outlet protection.
IMPORTANT: No more than four (4) dryers maximum should be connected to one (1) main
common duct with a vertical run.
NOTE: Ductwork should be laid out in such a manner where allowances are made at rear area of the
dryer for removal of rear service panels or guards.
Illus. Dshows the minimum cross section area for vertical multiple dryer venting. These figures must be increased
in proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is unusually long.
IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. For extended ductwork runs, a professional heating, ventilating, and
air-conditioning (HVAC) firm should be consulted for proper venting information.
