CAUTION!
Due to the weight and size of these vent hoods
and to reduce the risk of personal injury or
damage to the product, TWO PEOPLE ARE
REQUIRED FOR PROPER INSTALLATION.
WARNING!
To reduce the risk of fire or electric shock, do
not use this range hood with any external
solid-state speed control device. Any such
alteration from original factory wiring could
result in damage to the unit and/or create an
electrical safety hazard.
To reduce the risk of fire and to properly
exhaust air, be sure to duct air outdoors. Do
not vent exhaust air into spaces within walls or
ceilings or into attics, crawl spaces or garages.
WARNING: TO REDUCE THE RISK OF FIRE,
USE ONLY METAL DUCTWORK.
TO REDUCE THE RISK OF FIRE, ELECTRIC
SHOCK OR INJURY TO PERSONS, OBSERVE THE FOLLOWING:
A. Use this unit only in the manner intended
by the manufacturer. If you have any questions, contact the manufacturer.
B. Before servicing or cleaning unit, switch
power off at service panel and lock service
panel to prevent power from being switched
on accidentally.
For general ventilating use only. Do not use
to exhaust hazardous or explosive materials
and vapors.
Installation work and electrical wiring must be
done by qualified person(s). In accordance
with all applicable codes and standards
including fire-rated construction.
Sufficient air is needed for proper combustion
and exhausting of gases through the flue
(chimney) of fuel burning equipment to
prevent back drafting. Follow the heating
equipment manufacturer’s guideline and
safety standards such as those published by the
National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air Conditioning Engineers
(ASHRAE), and the local code authorities.

These hoods can be installed into a soffit, or
when there is no soffit, they can be installed
directly onto a wall.
48" and 36" wide models are available with
different appearances. Model numbers with
“YSS” have straight sides. Model numbers
ending with “WSS” have sides which taper
inwards from the bottom to the top.
Before you begin:
Decorative duct covers are available in 6" or
12" heights. The duct covers conceal the
ductwork running from the top of the hood to
the ceiling or soffit. Before you begin, you

Advance
Planning
Ductwork planning
•Determine the exact location of the vent hood.
•Plan the route for venting exhaust to the
outdoors.
•Use the shortest and straightest duct route
possible. For satisfactory performance, duct
run should not exceed 100 feet equivalent
length for any duct configurations.
•Refer to “Duct Fittings” chart to compute the
maximum permissable length for duct runs to
the outdoors. See page 6.
•Use metal ductwork. For 48" models,
3-1/4" x 24" or 10" round. For 30" and 36"
models, 7" to 10' round or 3-1/4" x 12" to
3-1/4" x 24".
•Install a wall cap with damper or roof cap at
the exterior opening.
Determine the size of the wall or roof cap for
your model and installation.
•Order the caps and any transitions needed in
advance. See “Duct and Duct Fittings” listed in
your local yellow pages. Be sure to include
equivalent lengths of caps and transitions when
calculating the total duct run. See “Duct
Fittings”, page 6.
48" Wide Model Duct Transitions
•Transition duct pieces are available for 48"
wide models. See illustrations of ZX48BY and
ZX48AY transition pieces on page 3.
Installation Framing for adequate support
These vent hoods are heavy. Adequate structural support must be provided. Hoods must be
secured to vertical studs or to studs in the
soffit.
•Additional studs may be required for a soffit
or wall mount installation. See Step 3, pages 8
and 9.
•We recommend that the vent hood and/or
duct cover be on site before final framing and
wall finishing. This will also help to accurately
locate the ductwork and electrical service.
•Installation will be much easier if the vent
hood is installed before the range or cooktop
below.
Decorative Duct Covers
Decorative duct covers are available for all
models. The duct covers conceal the ductwork
running from the top of the hood to the
ceiling or soffit. Duct covers are available in
6" or 12" heights.
You should:
•Determine the installation height from the
cooking surface.
– 36" max., 30" min.
•Measure 18" hood height.
•Select 6" or 12" duct cover to meet ceiling or
soffit height.
