Ductwork Design Tips
Wherever possible, reduce the number of
transitions and turns to as few sharp angles as
possible. Two staggered 45° angles are better than
one 90°.
Keep turns as far away from the hood exhaust as
possible, and allow as much space between bends
as possible.
For best performance, use round ducts instead of
rectangular, especially when elbows are required.
If multiple elbows are used, try to keep a minimum
of 24" of straight duct between them.
Avoid "S" or "back to back" use of adjacent elbows.
In regions where the weather gets extremely cold,
use thermal breaks, such as a short section of
nonmetallic duct, to avoid indoor heat loss. Locate
the break as close as possible to the outside pass-
through point.
Do not use flexible metal ductwork.
Do not use ductwork that is smaller in cross-
sectional area than the recommended types
above.
