American Dryer Corp MLG-45PDB Dryer Enclosure Requirements, Fresh Air Supply Requirements

Dryer Enclosure Requirements _______

AThe requirement to allow the dryer door to open completely is 33.5-inches (85.1 cm).

BA minimum overhead clearance of 12-inches (30.48 cm) is required.

CDryer should be positioned a minimum of 12-inches (30.48 cm) away from the nearest obstruction. 24-inches (60.96 cm) is recommended for ease of installation, maintenance, and service.

D1/16” (1.5875 mm) minimum is required.

EFlooring should be level or below dryer cabinet for ease of removing panels during maintenance.

FDryers 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.

G4-inch (10.16 cm) maximum.

Fresh Air Supply Requirements _______

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. Fresh air ventilation openings shall not be blocked and/or sealed. As a general rule, an unrestricted air entrance from the outdoors of 224 inch2 (1,445 cm2) is required for each dryer. (Based on 1 inch2 [6.5 cm2] per 1,000 Btu [252 kcal].)

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 = 20-inches (50.80 cm)

B = 22.5-inches (57.15 cm)

EXAMPLE: For a bank of 4 dryers, 2 unrestricted openings measuring 20-inches by 22.5-inches (50.80 cm by 57.15 cm) are acceptable.

To compensate for the use of registers or louvers used over the openings, this area must be increased by approximately 33%. Make-up air openings should not be located in an area directly near where exhaust vents exit the building.

Allowances must be made for remote or constricting passageways or where dryers are located at high altitudes or predominantly low pressure areas.

IMPORTANT: Make-up air must be 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.

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-limits, or lint chamber hi-limit protector thermostat. The dryer must be installed with a proper exhaust duct connection to the outside.

▲! 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.
