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.

BEFORE YOU BEGIN: It is advisable to
test run the range hood before installa-
tion.
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.
Only use rigid type metal ducting (plastic
ducting is generally not permit-ted by code).
Flexible ducting could restrict airflow by up
to 50%. Always fasten connections with she-
et metal screws and tape all joints with certi-
fied 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 8'' for
the models with 2 motors. You can increase
the duct size of the duct run but never de-
crease it.
Use the shortest and most direct route pos-
sible. 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
possible.
