Hood Exhaust - GE JVM1665 Installation Instructions Manual

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 6.
OUTSIDE TOP EXHAUST (EXAMPLE ONLY)
The following chart describes an example of one possible
ductwork installation.
DUCT PIECES
Equivalent lengths of duct pieces are based on actual tests and
reflect requirements for good venting performance with any vent hood.
*IMPORTANT: If a rectangular-to-round transition adapter 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.
OUTSIDE BACK EXHAUST (EXAMPLE ONLY)
The following chart describes an example of one possible
ductwork installation.
DUCT PIECES
Equivalent lengths of duct pieces are based on actual tests and
reflect requirements for good venting performance with any vent hood.
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.
