PLAN THE INSTALLATION

The standard installation for this rangehood is ducted to the outside of the house. This rangehood can also be installed as ductless which requires a Ductless Conversion Kit from the dealer. If desired, this rangehood can use an optional remote blower. If the remote blower is used, the internal blower must be removed and discarded. Both blowers cannot be used together.The remote blower connects using a separate wiring cable not supplied with the unit and should be installed at the same time as the ductwork.

The Isola chimney is adjustable and designed to meet varying ceiling heights as indicated in FIGURE 1. The chimney can be adjusted for ceilings between 7' 10 7/ 8" and 9' 3" depending on the distance between the bottom of the hood and the cooktop (distance x in FIGURE 1). For shorter ceilings, the entire chimney support (T in FIGURE 2) must be recessed up into the ceiling. For higher ceilings, build a solid structure down and attach the chimney support to this structure.

ATTACHING THE CHIMNEY

The rangehood attaches to the ceiling by a support inside the chimney (T) as illustated in FIGURE 2. This support must be attached to the ceiling before the canopy is attached to this support. Since this structure supports the weight of the canopy, it must be ﬁrmly attached to the ceiling. FOR CONCRETE CEILINGS

-Use inserts and screws provided. FOR WOOD CEILINGS - Use four 4" long wood screws. FOR PLASTER OR SHEET ROCK CEILINGS - If possible, the support must be attached to the ceiling joists. If not, a supporting structure behind the sheet rock must be built.

FIGURE 2

The ductrun should not exceed 35 equivalent feet if ducted with the required minimum of 3 1/4" by 10" rectangular duct and 55 equivalent feet if ducted with 9" round ductwork (Remote blowers require 9" round duct). Calculate the length of the ductwork by adding the equivalent feet in FIGURE 3 for each piece of duct in the system. An example is given in FIGURE 4.

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.
