MULTIPLE DRYER (Common) VENTING

HORIZONTAL VENTING

If it is not feasible to provide separate exhaust ducts for each dryer, ducts for individual dryers may be channeled into a common main duct. Each dryer is provided with a back draft damper. The individual ducts should enter the bottom or side of the main duct at an angle not more than 45° in the direction of the airflow. No more than four

(4) dryers should be connected to one (1) main common duct run.

The main common duct may be any shape so long as the minimum cross-sectional area is provided. The main duct should be tapered with the diameter increasing before each individual 10-inch duct is added (refer to Illus. C and Illus. D).

Illus. C

Horizontal venting must not exceed 20 feet - this calculation compensates for the use of a maximum of only one (1) elbow which is the outside outlet protection.

NOTE: Distance between dryer single ducts being connected to the main common duct must be a minimum of 31-3/8" (dryer width).

Duct work should be laid out in such a manner where allowances are made at rear area of the dryer for removal of rear service panels or guards.
