INSTALLATION INSTRUCTIONS COMMERCIAL DRYER INSTRUCTIONS POUR L’INSTALLATION D’UN SECHE-LINGE COMMERCIAL

L.P. Gas:

This dryer is also certified for use with L.P. (propane or butane) gases with appropriate conversion. No attempt shall be made to convert the appliance from the gas specified on the model/serial rating plate for use with a different gas without consulting the serving gas supplier.

Conversion must be done by a competent service technician. Gas conversion kit, part number W10233219, is available for purchase from your dealer. Full instructions are supplied with the kit.

Supply line requirements:

Provide a rigid gas supply line to the dryer location. It should be minimum 12.5 mm (1/2") ID. When acceptable to the gas supplier and local codes, 10 mm (3/8") ID rigid supply line may be used for lengths under 6.1 m (20'). Pipe-joint compounds resistant to the action of L.P. gas must be used.

Gas connection to the dryer itself should be made by means of a flexible gas hose suitable for the appliance and gas category in accordance with national installation regulations. If in doubt, contact the gas supplier. It should be minimum 10 mm (3/8") ID.

A means of restraint should be used between the appliance and the wall to avoid straining of the rigid gas supply when the appliance is moved. An appropriate length of chain and a wall hook is recommended.

The dryer gas inlet connection is a 3/8" NPT thread. An adapter is supplied for conversion to standard ISO.228-1 thread (3/8" BSP).

Check for leaks by using an approved noncorrosive leak- detection solution. Bubbles will show a leak. Correct any leaks found. A pressure measurement tapping is provided on the gas valve within the dryer, accessible after removal of the lower front panel.

The dryer must be disconnected from the gas supply piping system during any pressure testing of that system.

Venting Requirements

WARNING

Fire Hazard

Use a heavy metal vent.

Do not use a plastic vent.

Do not use a metal foil vent.

Failure to follow these instructions can result in death or fire.

WARNING:

To reduce the risk of fire, this dryer MUST BE

EXHAUSTED OUTDOORS.

n

Following these venting requirements will minimise ducting air noise.

n

Adequate ventilation has to be provided to avoid the backflow of gases into the room from other fuel-burning appliances, including open fires (i.e. available airflow into the room should match airflow out from the room).

n

The design of the flue system should be such that any condensate formed when operating the dryer from cold shall either be retained and subsequently re-evaporated or discharged. Following these instructions should adequately meet this requirement.

n

Dryer exhaust must not be connected into any gas vent, chimney, wall, ceiling, attic, crawlspace, or a concealed space of a building. Only rigid or flexible metal vent shall be used for exhausting.

n

Do not use an exhaust hood with a magnetic latch.

n

Do not install flexible metal vent in enclosed walls, ceilings, or floors.

n

Only a 102 mm (4") heavy metal exhaust vent and clamps may be used.

Heavy metal exhaust vent

n

Use clamps to seal all joints. Vent must not be connected or secured with screws or other fastening devices which extend into the interior of the vent and catch lint. Do not use duct tape.

Improper venting can cause moisture and lint to collect indoors, which may result in:

Moisture damage to woodwork, furniture, paint, wallpaper, carpets, etc.

Housecleaning problems and health problems.

IMPORTANT: Observe all governing codes and ordinances.

Use a heavy metal vent. Do not use plastic or metal foil vent.

Rigid metal vent is recommended for best drying performance and to avoid crushing and kinking.

Flexible metal vent must be fully extended and supported when the dryer is in its final position. Remove excess flexible metal vent to avoid sagging and kinking that will result in reduced airflow and poor performance.

The total length of flexible metal vent should not exceed 2.4 m

(7

3

⁄

4

ft.).

An exhaust hood should cap the vent to keep rodents and insects from entering the building.

Exhaust hood must be at least 305 mm (12") from the ground or any object that may be in the path of the exhaust (such as flowers, rocks, bushes, or snow).

If using an existing vent system, clean lint from the entire length of the system and make sure exhaust hood is not plugged with lint. Replace any plastic or metal foil vent with rigid metal or flexible metal vent.

Plan installation to use the fewest number of elbows and turns.

Allow as much room as possible when using elbows or making turns. Bend vent gradually to avoid kinking.

Vent outlet is located at the center of the bottom dryer back.

The vent can be routed up, down, left, right, behind the dryer, or straight out the back of the dryer.

Vent System Length

Maximum length of vent system depends upon the type of vent used, number of elbows, and type of exhaust hood.

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°.

If dryer is installed in a confined area, such as a bedroom, bathroom, or closet, provision must be made for enough air for combustion and ventilation. (Check governing codes and ordinances.) See “Recessed Area Installation Instructions” in the “Location requirements” section.

A 102 mm (4") outlet hood is preferred. However, a 64 mm

(2

1

⁄

2

") outlet exhaust hood may be used. A 64 mm (2

⁄

") outlet creates greater back pressure than other hood types.

For permanent installation, a stationary vent system is required.

Multiple Dryer Venting

n

A main vent can be used for venting a group of dryers. 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 the main vent if checked and cleaned frequently.

The room where the dryers are located should have make-up air equal to or greater than the airflow of all the dryers in the room.

n

A back-draft damper kit is needed and is available from a commercial laundry distributor; it should be installed in the vent of each dryer to keep exhausted air from returning into the dryers and to keep the exhaust in balance within the main vent. Unobstructed return air openings are required.

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.

The outside end of the main vent should have a sweep elbow directed downward. If the main vent travels vertically through the roof, rather than through the wall, install a 180° sweep elbow on the end of the vent at least 610 mm (2 ft.) above the highest part of the building. The opening in wall or roof shall have a diameter

13 mm (1/2") larger than the vent diameter. The vent should be centered in the opening.

Do not install screening or cap over the end of the vent.
