BEFORE YOU BEGIN:
It is advisable to test run the
range hood before installation.
Please read this entire manual and
ensure that you are fully conversant
with the requirements and limitations
outside wall. (See Figure 1) Only
use rigid type metal ducting (plastic
ducting is generally not permitted by
code). Flexible 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. You can increase the duct
size of the duct run but never
decrease it.
Use the shortest and most direct
route possible. Always, wherever
possible, 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.
