Non-ducted recirculation Configuration
1. Adjust the width of the flue mounting bracket
to equal the inside width of decorative flue.
Insert and tighten mounting screws to hold
bracket width.
2. Use mounting screws and drywall anchors
to secure flue mounting bracket to the
ceiling as shown.
3. Turn upper flue section upside down so
air vents are at the top. Slide upper flue
section into lower flue section.
4. Connect the non-ducted recirculation
plenum to the upper flue section with (4)
flat-head screws (supplied).
5. Install the reduction on the discharge collar.
6. Measure the distance from the top of the
reduction to the ceiling. Cut a length of 5"
round metal duct 5" shorter than this
dimension.
7. Fit duct section over the non-ducted
recirculation plenum. For best fit, make sure
duct seam is toward the front.
8. Set duct/flue assembly on hood with top
tilted away from wall. Reach around flue to
engage bottom of duct with discharge collar
on hood. Tilt flue up against wall. Duct seam
can be cut to length if necessary.
