COMMERCIAL MULTI LOAD DRYERS - MDG30, MC2, PC2, PNA, and MNA
VERTICAL VENTING
When vertical venting is used minimum duct diameter size is 10 inches (refer to
Illus. B below
), the duct work from the
dryer to the outside outlets
cannot
exceed 60 feet (refer to
Illus. B below
). 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.
Illus. B
VERTICAL SINGLE DRYER VENTING
NOTE A. OPENING MUST BE TWO (2) INCHES LARGER THAN THE DUCT (ALL THE
WAY AROUND). THE DUCT MUST BE CENTERED WITHIN THIS OPENING.
If the length of the duct run or quantity of elbows used exceeds the above noted specifications, the cross section area of
the duct work
must be
increased in proportion to the number of elbows or duct run added.
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.
