NOTES:
1. Minimum hood clearances are
zero inches (0”) to the rear,
sides and top of the hood.
2. Thirty inches (30”) is the
minimum distance between
the bottom of the hood and
any cooking surface.
3. Maximum effective clearance
from cooking surface to
bottom of hood is 36”
(914mm).
WARNINGS:
1. CAUTION: To reduce the
risk of fire and to properly
exhaust air, be sure to duct air
outside. Do not vent exhaust
air into spaces within walls or
ceilings, or into attics, crawl
spaces or garages.
2. Tape all duct joints securely
to prevent combustion by-
products, smoke or odors
from entering the home. This
will also improve the efficiency
of the system.
3. Do not exhaust more than one
vent into a single duct run.
4. Only use ductwork
constructed of materials
deemed acceptable by state,
municipal and local codes.

Cabinetry Planning
WARNING:
Failure to provide proper
minimum clearance may result in
a fire or safety hazard.
Duct Planning
NOTES:
1. Best performance is achieved
by using round duct instead of
rectangular, especially when
elbows are required.
2. If multiple elbows are needed,
ensure that there is a minimum
of 24” of straight duct between
any two elbows.
3. Avoid “S” or “back to back”
configurations caused by
adjacent elbows.
4. Thermal breaks, such as a short
section of non-metallic duct,
should be used in areas of
extreme cold.
5. A back-draft damper at the duct
outlet may also be required.
6. Do not use flexible metal duct.
7. Do not use ductwork that is
smaller in cross-sectional area
than the recommended size
duct.
8. Do not rely on duct tape alone to
seal duct joints. Use sheet metal
screws as require to support the
duct weight.
9. The vent hood and cooking
appliance(s) must be removable
if service is required.
10. Be certain that the ductwork does
not interfere with floor joists or
wall studs.
11. It is important to keep as few
turns in the duct run, and to keep
the run as short as possible.
Refer to Table below for recommended
maximum straight lengths of duct to
provide adequate performance. Refer
to Table on page 4 for recommended
sheet metal elbows, transitions, and
wall cap equivalent straight lengths.
NOTE:
The In Line Blower must be
located within 60 equivalent feet
of the hood canopy system.
