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
27 and 28) Only use rigid type metal ducting
(plastic ducting is generally not permitted by
code). Flexible ducting could restrict airflow
by up to 50%.

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.
Always fasten connections with sheet metal
screws and tape all joints with certified Sil-
ver 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. You
can increase the duct size of the duct run
but never decrease it. Use the shortest and
most direct route possible. Always, where-
ver possible, reduce the number of transi-
tions 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.
