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 7.
OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
The following chart describes an example of one possible ductwork installation.
OUTSIDE BACK 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.
NOTE: For back exhaust, care should be taken to align exhaust with space
between studs, or wall should be prepared at the time it is constructed by
leaving enough space between the wall studs to accommodate exhaust.
