BEFORE INSTALLING THE 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
At least two people are necessary for installation.
3
Fittings material is provided to secure the hood to
mosttypes of walls/ceilings, 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 temperatures 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
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.
