INSTALLATION NOTES
Step 6:
A damper (not included) should be installed to prevent back-draft where needed. A damper might also be required
local codes in order to qualify for building inspections. You can purchase dampers from most hardware stores, or call
our service line to order.
When a damper is not installed, a starting collar is provided in order to increase and raise the duct opening clearance
above the cabinet's base. Snap the adaptor's smaller end to hood's duct opening and secure by drilling 2 pilot holes
and fasten with screws (as shown on step 6, page 10).
Step 9:
The hood should NEVER be installed so that the front is
tilting downward. This will cause grease to back flow to the
front instead of the rear. ALWAYS level the hood or slightly
tilt front of hood upward. Some models includes 2 pre-
installed bumpers on the rear (or top) to aid the hood front
tilt upward when installed. Remove the bumpers simply by
peeling off if hood is preferred to be installed leveled. (refer
diagram)
Step 12:
A connector locking the electrical wiring on the electrical box is recommended and might be required by local codes.
Check with local inspectors, purchase and install the appropriate connector in order to meet all mandatory codes.
Call our service line to order connector.
