DUCTING
(Not applicable if the range hood is
used in re-circulating mode)
WARNING: Do not vent this
appliance into any other ductwork,
spaces between walls, ceilings,
attics, garages or any other confined
space.

External Venting Requirements

When planning new ductwork, always
look for the most direct route to the
outside. Venting can be done through
the roof or directly through the back

The ma nufactu rer dec lines all
responsibility in the event of failure
to observe the instructions given
here for installation, maintenance
and sui table op eration o f the
product. The manufacturer further
declines all responsibility for injury
due to negligence and the warranty
of the unit autom atically expires due
to improper maintenance and/or
installation.
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.
