Installation guide

TABLE 2. 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.
Ashort straight length of duct at the inlet of the remote blower gives the best delivery.
Transition to duct from the integral blower to remote duct transition as close as possible.
In order opreference, use:
Ist. 10” round duct
2nd. 8round duct
3rd. 3-1/4" x 14” duct
Ath. 7” round duct
5th. 3-1/4” x lO” 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.
. Prepare duct and conduit cut outs, see figures 2. Assembly of the 10” transition:
1 and 2 as needed. The transition supplied with the hood mounts to
the top.
Do not install transition until hood is
