BEFORE INSTALLING THE HOOD
1 For the most ecient 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 most
types 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.
