Dimensional Diagrams
The ducted Tratto Isola chimney can be adjusted for ceilings between 7’ 4 3/8” and 8’ 11” depending on the distance between the
bottom of the hood and the cooktop (distance x in above DUCTED diagram). The ductless Tratto Isola chimney can be adjusted for
ceilings between 7’ 10” and 8’ 11” depending on the distance between the bottom of the hood and the cooktop (distance x in above
DUCTLESS diagram). For higher ceiling installations, the High Ceiling Chimney Kit includes an additional support structure which adds
27 1/2" to the various ceiling heights in the gures above.

* it is highly recommended that
professional style cooking always be
vented to the outside.
WARNING! Product specications are subject to change without notication. Consult the installation instructions before you begin installing this rangehood.
Ductless Installations*
For installations where ductwork is
impossible or highly impractical, a
Ductless Conversion Kit is available. A
charcoal lter, which attaches under the
blower assembly, absorbs smoke and
odors. A ductless diverter assembly
directs the air out to a lower chimney
with vent grates cut into the sides.
Make your ductrun as straight and short as possible. The ductrun should not
exceed 35 equivalent feet if ducted with the required minimum of 6” round
duct. Count 45º angles as 3 feet, 90º elbows as 5 feet, and 90º at elbows as 12
feet.
For best results, use no more than three 90° elbows. Make sure that there is
a minimum of 24” of straight duct between elbows if more than one is used.
Do not install two elbows together. If you must elbow right away, do it as
far away from the hood’s exhaust opening as possible.
