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 figures above.
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 flat 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.
*it is highly recommended that professional style cooking always be
vented to the outside. | Rev.06/08 |
