Notes:
A. For venting up to the equivalent of 60', use standard steel ducting and elbows.
B. IMPORTANT: See installation instructions shipped with product before selecting island cabinetry,
making cutouts or beginning installation. For best performance, it is suggested that no more than
three 90 degree elbows be used with 6" or 3 1/4" x 10" duct. Each foot of metal flex duct counts as two
feet of rigid metal duct. Each flex elbow counts as two metal elbows. For longer duct runs of 31' to 60',
the restricter ring on the blower inlet housing must be removed. 6" round or 3 1/4 x 10" duct must
be used for ducting beyond 10' (up to 60'). Failure to follow ducting recommendations or use
recommended ducting accessories may result in substandard performance.
C. Count each 90 degree elbow as 5' of duct.
D. When venting electric ranges, 5" diameter round duct may be used to vent straight out the back of
appliance and directly through the wall for runs of 10' or less.
E. When venting dual-fuel ranges, 5" diameter round duct must be used for runs of 10' or less.
F. When installing through a slab, it is essential that the system be properly calculated, designed
and installed before the house is built, when the slab is poured.

The Long Duct Run
With Jenn-Air's powerful blower,
Jenn-Air downdraft grill-ranges
can vent up to the equivalent of
60 feet.
Here's how it works.
For duct runs equivalent to 30'
or less, install as received. For
duct runs equivalent to 31' to
60', simply snap out the restricter
ring on the blower inlet housing.
See installation instructions for
specific information.
