BEFORE INSTALLING HOOD
1.
For the most efficient air flow
exhaust, use a straight run or
as few elbows as possible.
CAUTION:
Vent unit to
outside of building, only.
2.
Almost two people are
necessary for installation.
3.
The hood is fitted with Screws
and Drywall Anchors suitable
for most surfaces, consult a
Qualified Installer, check if
they perfectly fit with your
cabinet/wall.
4.
Do not use flex ducting.
5.
COLD WEATHER installations
should have an additional
backdraft damper installed to
minimize backward cold air
flow and a nonmetallic
thermal break to minimize
conduction of outside tem-
peratures as part of the
ductwork. The damper should
be on the cold air side of the
thermal break.
The break should be as close
as possible to where the
ducting enters the heated
portion of the house.
6.
Remote blowers require a five
wire installation.
7.
Make up air: Local building
codes may require the use of
Make-Up Air Systems when
using Ducted Ventilation
Systems greater than
specified CFM of air
movement.
The specified CFM varies
from locale to locale. Consult
your HVAC professional for
specific requirements in your
area.
