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 two separate duct runs of
the required minimum of 6" round duct or 55
equivalent feet if ducted with one single 10"
round duct (when using optional
Duct Transi-
tion Kit
). 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.

RECIRCULATING INSTALLATIONS
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 three grease filters and set aside. Attach one charcoal filter to each end
of both blowers. Each charcoal filter attaches to the grid on the side of the blowers. Rotate the filter clockwise to install and counterclockwise
to remove
(FIGURE 1A)
. Replace all three 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.

MAKE YOUR CUT-OUTS
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
1/4"
Drill Bit to make
this hole. Install the cable. Use caulking to seal around the hole. DO NOT turn on the
power until installation is complete.
5.
Make the cut-out opening where the rangehood will be installed
