Ductfree Configuration
1. Use screws and wall anchors (sup-
plied) to secure the flue mounting
bracket to wall and ceiling as
shown.
2. Turn upper flue section upside down
so air vents are at the top. Slide up-
per flue section into lower flue sec-
tion.
3. Snap the plastic duct collar into the
hole in the bottom of the ductfree
plenum . Connect the ductfree
plenum to the upper flue section with
(4) flat-head screws (supplied).
4. Measure the distance from the top
of the discharge collar to the ceil-
ing. Cut a length of 6" round metal duct 6" shorter than this dimension.
5. Fit duct section over the plastic duct collar. For best fit, make sure duct seam is
toward the front.
6. 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.
Upper flue section can be cut to length if necessary.
7. Raise upper flue section and screw it to flue mounting bracket with (2) screws
(supplied). Screw lower flue section to hood with screws (supplied).
DUCTFREE FILTER
INSTALLATION
Ductfree Configuration Only
1. Purchase a ductfree filter kit (model no.
FILTERK3490CM or FILTERK3448”) from
your dealer.
2. Remove the grease filters by pushing them
back to compress the retaining springs, then
tilt filters down and out of front groove.
3. Holding the ductfree filter on its side, insert
one of the support rods, (supplied with
filters) into the upper groove in back that
runs parallel with the front of the hood, in
order to avoid that the filter might be sucked
onto the motor.
4. Fold the filter and insert it into the front, upper
groove.
5. Install the other support rods beneath filters.
6. Replace the grease filters.
