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 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.
