skip to the “Damage” section and proceed.
WARNING –
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.
The venting system must exhaust to the outside.
This hood can be vented vertically through upper cabinets or
horizontally through an outside wall . Ductwork is not included .
Exhaust connection:
The hood exhaust has been designed to mate with
standard 3
1
⁄
4
″
x 10
″
rectangular ducting or 7
″
diameter
round ducting .
If a 6
″
round duct is required, a rectangular-to-round
transition adaptor must be used* .
Do not use less than a
6
″
diameter duct.
Maximum duct length:
For satisfactory air movement, the total duct length
of a 3
1
⁄
4
″
x 10
″
rectangular, 6
″
or 7
″
diameter round
duct
should not exceed 65 equivalent feet. See
the WORKSHEET–CALCULATE TOTAL EQUIVALENT
DUCTWORK LENGTH section.
NOTE:
It is important that ducting be installed using the
most direct route and with as few elbows as possible .
This ensures clear venting of exhaust and helps prevent
blockages . Also, make sure dampers swing freely and
nothing is blocking the ducts . When applicable, install any
makeup (replacement) air system in accordance with local
building code requirements . Visit
GEAppliances.com
for
available makeup air solutions .
Elbows, transitions, wall and roofcaps, etc.,
present additional resistance to airflow and are equivalent
to a section of straight duct longer than their actual
physical size . When calculating the total duct length, add
the equivalent lengths of all transitions and adaptors plus
the length of all straight duct sections . The charts on the
following pages show you how to calculate total equivalent
ductwork length using the approximate feet of equivalent
length of some typical ducts .

WARNING –
Before beginning the
installation, switch power off at service panel and
lock the service disconnecting means to prevent power
from being switched on accidentally . When the service
disconnecting means cannot be locked, securely fasten
a prominent warning device, such as a tag, to the
service panel .

IMPORTANT:
If a rectangular-to-round
transition adaptor is used, the bottom
corners of the damper will have to be
cut to fit, using the tin snips, in order
to allow free movement of the damper .
Equivalent lengths of duct pieces
are based on actual tests and reflect
requirements for good venting
performance with any hood .
