The outside end of main vent should have a sweep elbow directed

downward.

If main vent travels vertically through the roof, rather than through

wall, install a 180° sweep elbow on end of vent at least 2 ft.

(610 mm) above surface of roof.

The opening in wall or roof shall have a diameter 1⁄2" (13 mm)

larger than vent diameter. Vent should be centered in opening.

Do not install screening over end of vent for best performance.

12" min.

(305 mm)*

A main vent can be used for venting a group of dryers. The main

vent should be sized to remove 5663 l/min. (200 CFM) of air per

dryer. Large-capacity lint screens of proper design may be used in

main vent if checked and cleaned frequently. The room where the

dryers are located should have make-up air equal to or greater than

CFM of all the dryers in the room.

Back-draft dampers are available from your distributor and should

be installed in the vent of each dryer to keep exhausted air from

returning into dryers and to keep exhaust in balance within main

vent. Unobstructed return air openings are required.

Although usually each single-load dryer should have an

unobstructed outdoor air opening of 24 in.

] per 1,000 Btu [252 kcal]), common make-up air

openings are also acceptable. Set up common openings so

the make-up air is distributed equally to all of the dryers. Keep

in mind that the coverage area must be increased by 33% to

account for the use of registers or louvers over the openings.

Also, make-up air openings should not be installed near the

location where exhaust vents exit the building.

Each vent should enter the main vent at an angle pointing in

the direction of the airﬂow. Vents entering from the opposite side

should be staggered to reduce the exhausted air from interfering

with the other vents.

The maximum angle of each vent entering the main vent should be

no more than 30°.

Keep air openings free of dry cleaning ﬂuid fumes. Fumes create

acids which, when drawn through the dryer heating units, can

damage dryers and items being dried.

A clean-out cover should be located on the main vent for periodic

cleaning of the vent system.

location. Pipe joint compounds that resist action of LP gas must be

used. Do not use TEFLON

®†

tape. With LP gas, piping or tubing

size can be 1⁄2" (13 mm) minimum. Usually, LP gas suppliers

determine size and materials used in the system.

Gas Supply Pressure Testing

A 1/8" (3 mm) NPT minimum plugged tapping, accessible for

gauge testing, must be installed immediately downstream of the

installed shut-off valve to the dryer (as shown above). The dryer

must be disconnected from the gas supply piping system during

any pressure testing of the system at test pressures in excess of

1/2" psig (352 kg/m

2

).

Alternate Method

The gas supply may also be connected using 3⁄8" (10 mm)

approved copper or aluminum tubing. If the total length of

the supply line is more than 20 ft. (6.1 m), larger tubing will

be required.

If using natural gas, do not use copper tubing. Pipe joint

compounds that resist action of type of gas supplied must

be used.

Shut-off valve required

The supply line must be equipped with a manual shut-off valve

installed within 6 ft. (1.8 m) of dryer in accordance with National

Fuel Gas Code, ANSI Z223.1. This valve should be located in

same room as dryer. It should be in a location that allows ease

of opening and closing. Do not block access to shut-off valve.

In Canada, an individual manual shut-off valve must be installed

in accordance with the B149 installation codes CAN/CGA

B149.1 and CAN/CGA B149.2.

Gas Supply Line

Flexible Metal Appliance Connector

It is recommended that a new ﬂexible stainless steel gas line,

design-certiﬁed by CSA International, be used for connecting the

dryer to the gas supply line. (The gas pipe which extends through

the lower rear of the dryer is provided with 3/8" [10 mm] male pipe

thread.)

NOTE: Do not kink or damage the ﬂexible stainless steel gas line

when moving the dryer.

Rigid Pipe Connection

The rigid pipe connection requires a combination of pipe ﬁttings to

obtain an in-line connection to the dryer.

INSTALLING LEVELING LEGS, COIN SLIDE, AND COIN BOX

On some models: The console houses the electronic control

board. The board is factory set for a dry time of 45 minutes.

Consult the tech sheet found inside the dryer toe panel to reset dry

time and for other options.

The card reading mechanism is not included, but is available from

your usual industry sources.

1. Prepare dryer for leveling legs

NOTE: Slide dryer onto cardboard or hardboard before moving

to avoid damaging ﬂoor covering.

Using two or more people, move dryer to desired installation

location.

Take tape off front corners of dryer. Open dryer and remove

the literature and parts packages. Wipe drum interior with a damp

cloth to remove any dust.

Take two cardboard corners from the dryer carton and place them

on the ﬂoor in back of the dryer. Firmly grasp the body of the dryer

and gently lay it on its back on the cardboard corners. Disconnect

power before making electrical connections.

2. Screw in leveling legs

Examine leveling legs and ﬁnd diamond

marking. Screw legs into leg holes by

hand. Use an adjustable wrench or

1" (25 mm) hex-head socket wrench

to ﬁnish turning legs until diamond

marking is no longer visible. Then ﬁt

a covered foot boot over each leg foot.

To protect the ﬂoor, use a large piece of cardboard from the dryer

carton. Stand dryer up on the cardboard. Slide the dryer until

it is close to its ﬁnal location. Leave enough room for electrical

connection and to connect the exhaust vent.

1. Install coin slide and coin box

Remove the service door of the meter case by lifting it up at the

back. Install the money-accepting device. (Refer to manufacturer’s

instructions for proper installation.)

For dryers using coin slides, use the adapter kit supplied with the

dryer.

Replace the meter case service door. Put the coin vault with lock

and key in the meter case opening.

Remove cardboard or hardboard from under dryer. Adjust the legs

of the dryer up or down until the dryer is level.

2. Install added security device

Check that power is not supplied to the dryer.

Open and remove the service door.

Insert the narrow part of the security cone into the oblong hole in

the bottom rear of the meter case assembly.

Pass the security bolt through this cone and thread it by hand into

the cage nut below the oblong hole.

Tighten the security bolt by hand a few turns before using a wrench

to tighten until snug.

The factory-installed timer is set to provide 45 minutes (4 pins)

of drying time when activated by the coin slide. Timer cams

for 30-minute (6 pins) and 60-minute (3 pins) drying times are

included in the parts bag.

The coin slide mechanism, service door lock and key, and coin box

lock and key may not be included but are available from the usual

industry sources.
