13

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 2 feet(24-inches)from the nearest obstruction (i.e., wall) for ease of installation, maintenance, and service. Bulkheads and partitionsshould be made from noncombustible materials. The clearance between the bulkhead header and the dryermust be a minimum of4-inches(10.16 cm) and must not extend more than4-inches(10.16 cm) to the rear of the front. A2-inch(5.08 cm) clearance is required between the bulkhead facing and the top of the dryer.

NOTE: Bulkhead facingshould not be installed until after the dryer is in place. Ceiling areamust be located a minimum of12-inches(30.48 cm) above the dryer top console (module) and18-inches(45.72 cm) for steam models.

NOTE: When fire sprinkler systems are located above the dryers, a minimum of18-inches(45.72 cm) above the dryer console (module) is required. Dryers may be positioned sidewall to sidewall, however, 1 or2-inches(2.54 or 5.08 cm) is suggested for ease of installation and maintenance. Allowancesmust be made for the opening and closings 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 themake-upair is inadequate, drying time and drying efficiencywill be adversely affected. Ignition problems and sail switch "fluttering" problems may result, as well as premature motor failure from overheating.

Air supply (make-upair)must be given careful consideration to assure proper performance of each dryer. An unrestricted source of air is necessary for each dryer. An airflow of 3,700 cfm (cubic feet per minute) (104.77 cmm [cubic meters per minute])must be supplied to each gas dryer and 4,400 cfm (cubic feet per minute) (124.59)must be supplied to each steam dryer. As a general rule, an unrestricted air entrance from the outdoors (atmosphere) of a minimum of 4 square feet (0.37 square meters) is required for each gas dryer and a minimum of 4.75 square feet (0.44 square meters) for each steam dryer.

To compensate for the use of registers or louvers used over the openings, this make-upairmust be increased by approximatelythirty-threepercent (33%).Make-upair openingsshould not be located in an area directly near where exhaust vents exit the building.

It is not necessary to have a separatemake-upair opening for each dryer. Commonmake-upair openings are acceptable. However, theymust be set up in such a manner that themake-upair is distributed equally toALL the dryers. The dryermust be installed with provisions for adequate combustion andmake-upair supply.

EXAMPLE: For a bank of six (6) dryers, two (2) unrestricted openings measuring 3 feet by 4 feet (0.91 meters by 1.21 meters) (12 square feet each [1.11 square meters]) is 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-upairmust be provided from a source free of dry cleaning solvent fumes.Make-upair that is contaminated by dry cleaning solvent fumes will result in irreparable damage the motors and other dryer components.

NOTE: Component failure due to dry cleaning solvent fumes willVOID 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, burnerhi-limits,or basket (tumbler)hi-heatthermostats. The dryermust be installed with a proper exhaust duct connection to the outside.

CAUTION: This dryer produces combustible lint andmust be exhausted to the outdoors.

CAUTION: DRYERMUST BE EXHAUSTED TO THE OUTDOORS.

CAUTION: IMPROPERLY SIZED OR INSTALLED EXHAUST DUCTWORK CAN CREATE A POTENTIAL FIRE HAZARD.

NOTE: When a dryer is exhausted separately,it is recommended that a back draft damper be installed.

NOTE: When dryers are exhausted into a multiple (common) exhaust line, each dryermust 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.

When single dryer venting is used, the ductwork from the dryer to the outside exhaust outlet must 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 outletmust not exceed 20 feet (6.09 meters). The shape of the ductworkis not so critical so long as the minimumcross-sectionalarea is provided. It is suggested that the use of 90º turnsbe avoided; use 30º and/or 45º bends/angles instead. The radius of the elbowsshould preferably be 1-1/2times 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) elbowsshould be used in the exhaust duct run. If more than two (2) elbows are used, thecross-sectionalarea of the ductworkmust be increased in proportion to the number of elbows used.

ALL ductworkshould 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 jointsmust be taped to prevent moisture and lint from escaping into the building. Inspection doorshould be installed at strategic points in the exhaust ductwork for periodic inspection and cleaning of lint from the ductwork.

IMPORTANT: Exhaust back pressure measured by a manometer in the exhaust ductmust be no less than 0 andmust 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 openingmust be 2-inches(5.08 cm) larger than the duct (all the way around). The ductmust be centered within this opening.
