COMMERCIAL MULTI LOAD DRYERS - MDG30, MC2, PC2, PNA, and MNA
Illus. C
(refers to the
previous page 5-5
) shows the minimum cross-section area for horizontal multiple dryer venting.
These figures
must be
increased in proportion if the main duct run from the last dryer to where the exhaust has
numerous elbows or is unusually long.
IMPORTANT:
For extended duct work runs, the cross-section area of the duct can only be increased to an
extent. For extended duct work runs, a professional HVAC firm
should be
consulted for
proper venting information.
VERTICAL VENTING
ILLUS. D
The maximum length of venting from the last dryer to where it exhausts...
Vertical venting
must not
exceed 2 feet - this calculation compensates for the sue of a maximum of three (3)
elbows including the two (2) elbows creating the 180
°
(turned down-
ward 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” (dryer width).
Ducts 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.
Illus. D
shows the minimum cross-section area for vertical multiple dryer venting. These figures
must be

proportion if the main duct run from the last dryer to where it exhausts has numerous elbows or is unusually long.
IMPORTANT:
For extended duct work runs, the cross-section area of the duct can only be increased to an
