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, ventilating, and

air-conditioning (HVAC) firm should be consulted for proper venting information.

VERTICAL VENTING

Illus. D

MULTIPLE DRYER VENTING (VERTICAL)

The maximum length of venting from the last dryer to where it exhausts:

Vertical venting must not exceed 25 feet (7.62 meters)  this calculation compensates for the use of a maximum

of three (3) elbows including the two (2) elbows creating the 180° (turned downward) outside outlet protection.

IMPORTANT: No more than four (4) 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 (79.7 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. D shows the minimum cross section area for vertical 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 HVAC firm should be

consulted for proper venting information.
