American Dryer Corp ML-78 installation manual Not be Reduced Anywhere Down Stream of the Dryer

IMPORTANT: Minimum duct work diameter for horizontal venting is 10-inches and for vertical venting the minimum is 12-inches.

NOTE: Where the exhaust duct work passes through a wall, ceiling, or roof made of combustible materials, the opening must be 2-inches larger (all the way around) than the duct. The duct must be centered within this opening.

a.Outside Duct Work Protection

1)To protect the outside end of horizontal duct work from the weather, a 90° elbow bent downward should be installed where the exhaust exits the building. If the duct work 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 or caps on the outside of opening of exhaust duct work.

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 duct work 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 be avoided; use 30° and/or 45° angles instead. The shape of the exhaust duct work is not critical so long as the minimum cross section area is provided.

IMPORTANT: Minimum duct size for a dryer that is vented horizontally is 10-inches for a round duct or an equivalent of 80 square inches. THE DUCT SIZE MUST

NOT BE REDUCED ANYWHERE DOWN STREAM OF THE DRYER.

IMPORTANT: Exhaust back pressure measured by a manometer at each basket (tumbler) exhaust duct area should not exceed 0.3 inches of water column.
