To calculate the length of the duct system you require, subtract the equivalent feet for each “Duct
piece” (Table Below) used in the system from the “Recommended maximum run” (Table Below).
The longest duct run that is acceptable (if completely straight) is 50 feet. The number of duct pieces
(elbow, transition, etc.) installed in your duct run will determine the maximum length the duct run can
be. Please refer to the example below:
Duct Run Calculation:
Recommended maximum run
6” or 8” round duct
50 ft
Duct piece deduction
Each 90º elbow used
9 ft
Each 45º elbow used
5 ft
Each 6” to 3/14 x 10” transition
used
7 ft
Side wall cap with damper
7 ft
Roof cap
7 ft
Duct Run Calcuation example:
One roof cap, two 90º elbows, and one 45º elbow
used:
7ft + 9ft + 9ft + 5ft =
30ft
used.
The above duct pieces used are equivalent to 30ft
of a straight duct run. Subtract 30ft from the al
-
lowable 50ft. The remaining distance of 20ft is the
longest that the straight ducting (in addition to the
duct pieces) can be.
