HOOD EXHAUST
NOTE: Read these next two pages only if you plan to vent your exhaust to the outside. If you plan to
recirculate the air back into the room, proceed to page 11.
OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
The following chart describes an example of one possible ductwork installation.
* IMPORTANT:
If a rectangular-to-round transition adaptor is used, the bottom corners of the damper will have
to be cut to fit, using the tin snips, in order to allow free movement of the damper.
