IT IS HIGHLY RECOMMENDED THAT PROFESSIONAL STYLE COOKING ALWAYS BE VENTED TO THE OUTSIDE. For recirculating
installations (FIGURE 1), Charcoal Filters are necessary. Remove all grease filters and set aside. Attach one charcoal filter to each end
of the blower. Each charcoal filter attaches to the grid on the side of the blower. Rotate the filter clockwise to install and counterclockwise
to remove (FIGURE 1A). Replace all grease filters. Recirculating installations also require some duct work to divert the air out of the top or
face of the cabinet or custom hood. The duct work must not terminate inside the cabinet or custom hood.

PLAN YOUR DUCTWORK
To ensure that the blower performs to its highest
possible capacity, ductwork should be as short
and straight as possilbe.
The ductrun should not exceed 35 equivalent
feet if ducted using the required minimum of 6"
round duct. Calculate the length of the ductwork
by adding the equivalent feet in FIGURE 2 for
each piece of duct in the system An example
is given in FIGURE 3.

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.

1. Disconnect and move freestanding range from cabinet opening to provide easier access
to upper cabinet or custom hood. Put a thick, protective covering over cooktop, set-in range
or countertop to protect from damage or dirt.
2. Determine and clearly mark with a pencil the center line on the cabinet or custom hood
where the rangehood will be installed.
3. Determine and make all necessary cuts in the wall and/or ceiling for the ductwork. Install
the ductwork before the rangehood.
4. Determine the proper location for the Power Supply Cable. Use a 1
this hole. Install the cable. Use caulking to seal around the hole. DO NOT turn on the
3.0 feet
power until installation is complete.
