Ductwork
To Find Required Duct Length:
• Measure from house duct flange to bottom
of support frame. (Dimension A)
– Add at least 1” to Dim. A for duct overlap at
the top.
– Subtract 1-3/4” for hood insertion into the
bottom of the frame to determine required
duct length.
• Cut the 6” duct to required length.
Note:
The bottom of the duct must be external
(female) connection to the top of the hood.
The bottom end should be flared slightly, to
facilitate installation of the hood.
• Install duct up through support frames and
attach to house ducting with sheet metal
screws.
• Seal the connection with duct tape.
