BEFORE YOU BEGIN: It is advisable to test
run the range hood before installation.
BEFORE STARTING – please read this
entire document and ensure you are fully
conversant with the require-ments and li-
mitations. These units weigh approximately
125lbs and therefore require a minimum of
two people to install.
BEFORE YOU BEGIN
The manufacturer declines all responsibility
in the event of failure to observe the instruc-
tions given here for installation, maintenan-
ce and suitable operation of the product. The
manufacturer further declines all responsibi-
lity for injury due to negligence and the war-
ranty of the unit automatically expires due
to improper maintenance and/or installation.
Only use rigid type metal ducting (plastic duc-
ting is generally not permit-ted by code). Flexi-
ble ducting could restrict airflow by up to 50%.
Always fasten connections with sheet metal
screws and tape all joints with certified Silver
Tape or Duct Tape.
Do not use screws to fasten ductwork to the
hood,
only use tape as the screws will stop the
dampers from opening and your hood will not
work. This hood requires a 6” round duct outlet
for the models with 1 motor, and 8’’ for the mo-
dels with 2 motors. You can increase the duct
size of the duct run but never decrease it.
Use the shortest and most direct route possi-
ble. Always, wherever reduce the number of
transitions and turns with as few sharp angles
as possible.
Two staggered 45 degree angles are better
than one 90 degree. Make these turns as far
away from the motor exhaust as possible, with
as much space between each bend as possi-
ble.
Duct Run Calculation
The maximum duct run before effecting the
performance of the hood is 100’. Calculate your
duct run by measuring linear feet and adding
the elbows, transitions and caps based on the
table alongside.
DUCTING
(Not applicable if the range hood is used in
recirculing model)
WARNING:
Do not vent this appliance into
any other ductwork, spaces between walls,
ceilings, attics, garages or any other confi-
ned space.
External Venting Requirements.
When planning new ductwork, always look
for the most direct route to the outside. Ven-
ting can be done through the roof or directly
through the back outside wall. (See Figure
1). Recommanded 18” from the top of the
hood to the first elbow.
