Ductwork installation guidelines

For safety reasons, ducting should vent directly
outdoors (not into an attic, underneath the house,
into the garage or into any enclosed space).
Keep duct runs as short and straight as possible.
Duct fittings (elbows and transitions) reduce air flow
efficiency.
Back to back elbows and „S" turns give very poor
delivery and are not recommended.
A short straight length of duct at the inlet of the
remote blower gives the best delivery.
Transition to duct from the integral blower or remote
duct transition as close to the downdraft as is pos-
sible.
In order of preference, use
1st. 10" round duct
2nd. 8" round duct
3rd. 3-1/4" x 14" duct
4th. 7" round duct
5th. 3-1/4" x l0" duct
6th. 6" round duct
The use of flexible metal round duct should only be
used when no other duct fitting exists. Limit use to
short lengths and do not crush when making
corners.
