IMPORTANT: No more than eight (8) dryers maximum should be connected to one (1) main
common duct with a vertical run.
NOTE: Distance between dryer single ducts being connected to the main common duct must be a
minimum of 31-3/8” (79.69 cm) dryer width.
Ductwork 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.
Illus. C (refer to the previous page) shows the minimum cross section area for multiple dryer venting. These
figures must be increased in proportion if the main duct run from the last dryer to where it exhausts has
numerous elbows or is unusually long.
IMPORTANT: For extended ductwork runs, the cross section area of the duct can only be increased
to an extent. For extended ductwork runs, a professional heating, venting, and air
conditioning (HVAC) firm should be consulted for proper venting information.
