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
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 180º (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:
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 heating, ventilating, and
air-conditioning (HVAC) firm
should be
consulted for proper venting information.
