Page 14
C. DRYER ENCLOSURE REQUIREMENTS
Even though a 12-inch (30.48 cm) clearance is acceptable, it is recommended that the rear of the dryer be positioned
approximately 24-inches (60.96 cm) from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and
service. Bulkheads and partitions should be made from noncombustible materials. The clearance between the bulkhead
header and the dryer must be a minimum of 4-inches (10.16 cm) and must not extend more than 4-inches (10.16 cm) to
the rear of the front. A 2-inch (5.08 cm) clearance is required between the bulkhead facing and the top of the dryer.
NOTE: Bulkhead facing should not be installed until after the dryer is in place. Ceiling area must be located
a minimum of 12-inches (30.48 cm) above the dryer top console (module).
NOTE: When fire sprinkler systems are located above the dryers, a minimum of 18-inches (45.72 cm) above
the dryer console (module) is required. Dryers may be positioned sidewall to sidewall, however, 1 or
2-inches (2.54 or 5.08 cm) is suggested for ease of installation and maintenance. Allowances must be
made for the opening and closing of the control door and the lint door.
D. FRESH AIR SUPPLY REQUIREMENTS
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 be continually replenished from the outdoors. If the make-up air is
inadequate, drying time and drying efficiency
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. An unrestricted
source of air is necessary for each dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere)
of a minimum of 350 square inches (2258.1 square cm) is required for each gas dryer (based on 1 square inch per 1000
Btus).

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.
is not necessary to have a separate make-up air opening
It
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
EXAMPLE: For a bank of four (4) dryers, two (2) unrestricted
openings measuring 26-inches by 26.9-inches (66.1 cm by
68.4 cm) each are acceptable.
Allowances must be made for remote or constricting
passageways or where dryers are located at excessive
altitudes or predominantly low pressure areas.
ALL the dryers.
A = 26-Inches (66.1 cm) B = 26.9-Inches (68.4 cm)
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.
E. EXHAUST REQUIREMENTS
1. General Exhaust Ductwork Information
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, overheating of the dryer, and
shutdown of the burner by the airflow (sail) switches, burner hi-limits, or basket (tumbler) hi-heat thermostats. The
dryer must be installed with a proper exhaust duct connection to the outside.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A
POTENTIAL FIRE HAZARD.
NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryer must be supplied with a
back draft damper.
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. Single or independent dryer venting is recommended.
113374- 4Telephone 01422 82228211
Page 16
When single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet should not exceed 20
feet (6.09 meters). In the case of multiple (common) dryer venting, the distance from the last dryer to the outside
exhaust outlet should not exceed 20 feet (6.09 meters). The shape of the ductwork
minimum cross-sectional area is provided. It is suggested that the use of 90º turns
bends/angles instead. The radius of the elbows should preferably be 1-1/2 times the diameter of the duct. Excluding
basket (tumbler)/dryer elbow connections or elbows used for outside protection from the weather, no more than two
(2) elbows should be used in the exhaust duct run. If more than two (2) elbows are used, the cross-sectional area
of the ductwork must be increased in proportion to the number of elbows used.
ALL 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.
ductwork joints must be taped to prevent moisture and lint from escaping into the building. Inspection doors shouldbe installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.
is not critical as long as the
be avoided; use 30º and/or 45º
IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust duct must be no less than 0
and must not exceed 0.3 inches (0.74 mb) of water column (W.C.).
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.
ALL
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: DO NOT use screens, louvers, or caps on the outside opening of the exhaust ductwork.
2. Single Dryer Venting
Where possible, it is suggested to provide a separate exhaust duct for each dryer. The exhaust duct 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 in the ducting
exhaust ductwork
is not critical as long as the minimum cross section area is provided.
IMPORTANT: The minimum duct size for a gas unit is 16-inches (40.64 cm) for a round duct and
14-1/4” x 14-1/4” (36.2 cm x 36.2 cm) for a square duct. THE DUCT SIZE MUST NOTBE REDUCED ANYWHERE DOWNSTREAM OF THE DRYER.
12JLA Limited113374-4
be avoided; use 30° and/or 45° angles instead. The shape of the
Page 17
IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust duct area
must be no less than 0 and must not exceed 0.3 inches (0.74 mb) of water column (W .C.).
It is suggested that the ductwork from each dryer not exceed 20 feet (6.09 meters) with no more than two (2)
elbows (excluding dryer connections). If the ductwork exceeds 20 feet (6.09 meters) or has numerous elbows, the
cross-sectional area of the ductwork must be increased in proportion to the length and number of elbows in it. In
calculating duct size, the cross-sectional area of a square or rectangular duct must be increased twenty percent
(20%) for each additional 20 feet (6.09 meters). The diameter of a round exhaust duct should be increased ten
percent (10%) for each additional 15 feet (4.57 meters). Each 90º elbow is equivalent to an additional 40 feet (12.19
meters), and each 45º elbow is equivalent to an additional 20 feet (6.09 meters).
IMPORTANT: For extended ductwork runs, the cross section area of the ductwork can only be increased to
an extent. Maximum proportional ductwork runs cannot exceed 20 feet (6.09 meters) more
than the original limitations of 20 feet (6.09 meters) with two (2) elbows. When the ductwork
approaches the maximum limits as noted in this manual, a professional heating, ventilating, and
air-conditioning (HVAC) firm should be consulted for proper venting information.
ALL 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.
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: 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.

3. Multiple Dryer (Common) Venting
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 side of the main duct at an angle not
more than 45° in the direction of the flow and should be spaced at least 46-inches (116.84 cm) apart. The main
duct should be tapered, with the diameter increasing before each individual 16-inch (40.54 cm) duct is added.
IMPORTANT: When exhausted into a multiple (common) exhaust line, a back draft damper must be installed
at each dryer duct.
IMPORTANT: No more than three (3) dryers should be connected to one (1) main common duct.
The main duct may be any shape or cross-sectional area, as long as the minimum cross section area is provided. The
illustration above shows the minimum cross section area for multiple dryer round or square venting. These figures
must be increased 10 square inches (64.52 square centimeters) when rectangular main ducting is used, and the
ratio of duct width to depth should not be greater than 3-1/2 to 1. These figures must be increased in proportion
if the main duct run to the last dryer to where it exhausts to the outdoors is unusually long (over 20 feet [6.09
meters]) or has numerous elbows (more than two [2]) in it. In calculating ductwork size, the cross-sectional area of
a square or rectangular duct must be increased twenty percent (20%) for each additional 20 feet (6.09 meters).

5. Heat Circuit Operational Test
a. Gas Models
1) When the dryer is first started (during initial start-up), the burner has a tendency not to ignite on the first
attempt. This is because the gas supply piping is filled with air , so it may take a few minutes for this air to
be purged from the lines.
a) If the dryer is equipped with a Direct Spark Ignition (DSI) system, the DSI control module has internal
diagnostics. If ignition
“LOCKOUT” until it is manually reset. To reset the DSI system, open and close the main door and
restart the dryer.

NOTE: During the purging period, check to be sure that ALL gas shutoff valves are open.
2) Once ignition is established, a gas pressure test should be taken at the gas valve pressure tap of each dryer
to ensure that the water column (W.C.) pressure is correct and consistent.
NOTE: Water column pressure requirements (measured at the gas valve pressure tap):
Natural Gas---------------------3.5 Inches (8.7 mb) Water Column.
Liquid Propane (L.P .) Gas ----10.5 Inches (26.1 mb) Water Column.
IMPORTANT: There is no regulator provided in an L.P . dryer . The water column pressure must be regulated
at the source (L.P . tank) or an external regulator must be added to each dryer.
6. Make a complete operational check of ALL safety-related circuits (i.e., lint drawer switch and sail switch on gas
models).
NOTE: To check for proper sail switch operation, open the main door and while holding main door switch
plunger in, start the dryer . The dryer should start but the heat circuit should not be activated (on). If
the heat (burner) does activate, shut the dryer off and make the necessary adjustments.
7. A reversing basket (tumbler) dryer must never be operated with less than a 63 pound (28.57 kg) load (dry weight).

PROCEDURE FOR FUNCTIONAL CHECK
OF REPLACEMENT COMPONENTS
1. For Heat Control Module Ignition Circuit
a. For Models With Johnson Controls Direct Spark Ignition (DSI) Module (G760)
Theory Of Operation:
Start the drying cycle. When the gas burner ignites within the
chosen trial for ignition time (6-seconds), the flame sensor detects
gas burner flame and signals the DSI module to keep the gas
valve open as long as there is a call for heat. The DSI module
will “LOCKOUT” if the gas burner flame
end of the trial for ignition period. The trial for ignition period
be repeated for a total of three (3) retries/trials (the initial try and
two [2] more retries/trials). If the flame
of the third retry/trial (inter-purge period of 30-seconds) the DSI
module will “LOCKOUT” (light emitting diode [L.E.D.] flashes).

will
is not sensed at the end
A steady L.E.D. indicator indicates normal operation.
No L.E.D. indicator indicates a power or an internal failure has occurred.
b. For Models With Hot Surface Ignition (HSI) Module
1) Start the drying cycle.
2) The HSI will turn on, and after approximately 4-seconds the
ignitor will shut off and the gas valve
Ignition (flame) should now be established.
3) With the burner flame on, remove the flame sensor wire from
the S2 terminal of the HSI module. The burner flame must
shut off immediately .
4) Stop the drying cycle, with the flame sensor wire still removed, restart the drying cycle.
5) The HSI will turn on, and after a few seconds later the gas valve
Ignition (flame) should be evident for approximately 7-seconds and then shut off.
6) The HSI module will attempt to light burner only “once.” If flame

7) Functional check of the HSI module is complete.
Replace the flame sensor wire from the S2 terminal to the HSI module.

PHASE 7 NON-COIN SYSTEM DIAGNOSTICS
IMPORT ANT : YOU MUST DISCONNECT AND LOCKOUT THE ELECTRIC SUPPLY AND THE
GAS SUPPL Y BEFORE ANY COVERS OR GUARDS ARE REMOVED FROM
THE MACHINE TO ALLOW ACCESS FOR CLEANING, ADJUSTING,
INST ALLA TION, OR TESTING OF ANY EQUIPMENT PER OSHA (OccupationalSafety and Health Administration) STANDARDS.
ALL major circuits, including door, microprocessor temperature sensor, heat and motor circuits are monitored. The
Phase 7 non-coin microprocessor controller (computer) will inform the user, via the light emitting diode (L.E.D.) display
of certain failure messages, along with L.E.D. indicators on the input/output (I/O) board on the back panel of the front
right control door.
