WARNING - TO REDUCE THE RISK OF A RANGE TOP GREASE FIRE:
a) Never leave surface units unattended at high settings. Boilovers cause smoking and greasy
spillovers that may ignite. Heat oils slowly on low or medium settings.
b) Always turn hood ON when cooking at high heat or when flambeing food. (i.e. Crepes Suzette,
Cherries Jubilee, Peppercorn Beef Flambe’).
c) Clean ventilating fans frequently. Grease should not be allowed to accumulate on fan or filter.
d) Use proper pan size. Always use cookware appropriate for the size of the surface element.

Installation Instructions
Mounting Height, Clearance, & Ducting
A minimum of 8” round duct is recommended to maintain maximum air flow eciency.
Always use rigid type metal ducts only. Flexible ducts could restrict air flow by up to 50%.
Use calculation worksheet to compute total duct work (Page 11).
ALWAYS, when possible, reduce the number of transitions and turns. If a long duct run is required,
increase duct size from 8” to 10”.
If turns or transitions are required: Install as far away from duct opening and as far apart between
the two transitions as possible.
Minimum mount height between range top to hood bottom should be no less than 24”.
Maximum mount height should be no higher than 34”.
It is important to install the hood at the proper mounting height. Hoods mounted too low could result
in heat damage and fire hazard; while hoods mounted too high will be hard to reach and will loose its
performance and eciency.
If available, also refer to range manufacturer’s height clearance requirements and recommended
hood mounting height above range. Always check your local codes for any dierences.
Duct cover extension kit available for ceiling heights up to 12 feet. Turn to the List of Parts and
Accessories section for part number and ordering information.
For shipment and installation damages:
ŹPlease fully inspect unit for damage before installation.
ŹIf the unit is damaged in shipment, return the unit to the store in which it was bought for repair or
replacement.
ŹIf the unit is damaged by the customer, repair or replacement is the responsibility of the customer.
ŹIf the unit is damaged by the installer (if other than the customer), repair of replacement must be
made by arrangement between customer and installer.

Mounting the Hood
Ceiling Preparation
1. Determine hood mounting location and
temporarily tape paper template (included with
the hood) to the ceiling.
2. Cut-out internal shaded area of template
to allow the ducting and electrical to pass
through.
3. Add wood blocking (min. 2” x 4”) onto ceiling
joists to reinforce ceiling above the drywall.
(FIG. C1).
4. Secure (2) 1-1/2” wood screws into points A
and B of the paper template (FIG. B). Do not
completely tighten screws, leave approximately
1/4” exposed.
Hood Preparation
5. Remove screws securing top and bottom
support frames together.
6. Adjust support frame to accommodate the
desired hood height and re-assemble the frame
using the previously removed screws (2 screws
for each support frame arm). (FIG. C2).

7. Hood heights between 40” to 50” require lateral support brackets to be installed to the two top
support frame cut o arms and their corresponding bottom support frame arms. Install lateral
support brackets by (12) M4 x 8 sheet metal screws shown in FIG. D.
8. Hood heights between 45” to 50” require a square support bracket to be installed inside the
support frame. Install square support bracket to top support frame arms by (8) M4 x 8 sheet metal
screws. (FIG. E1) Top support frame arms extend past lower support frame bracket with shorter
hood heights. (FIG. E2).
9. Lift support frame assembly up to the ceiling making sure the word “front” on the top support
frame faces the front of the hood where the controls will be located (FIG. F). The key-holes on the
top support frame should cover the wood screws previously installed in the ceiling. Slide support
frame towards narrow end of key-holes to lock the frame in place.
10. Install the last (2) 1-1/2” wood screws with washers into the two remaining corners of the top
support frame to secure it to the ceiling. Tighten all screws.
