Installation Instruction

6
Cold weather installations
An additional backdraft damper should be installed to minimize
backward cold air ow and a thermal break should be installed
to minimize conduction of outside temperatures as part of the
vent system. The damper should be on the cold air side of the
thermal break.
The break should be as close as possible to where the vent
system enters the heated portion of the house.
Makeup air
Local building codes may require the use of makeup air systems
when using ventilation systems with greater than specied CFM
of air movement. The specied CFM varies from locale to locale.
Consult your HVAC professional for specic requirements in your
area.
Venting Methods
This range hood is factory set for venting through the roof or
through the wall.
The vent system needed for installation is not included.
A 6" (15.2 cm) round vent system is recommended.

Calculate Vent System Length
The recommended vent system is 6" (15.2 cm) round vent with a
maximum length of 35 ft (10.7 m). For the best performance, use
no more than three 90° elbows.
To calculate the length of the system, add the equivalent feet
(meters) for each of the vent pieces used in the system.

Example vent system: 6" (15.2 cm)
Maximum Length = 35 ft (10.7 m)
1 - 90° elbow = 5 ft (1.5 m)
1 - wall cap = 0 ft (0 m)
9 ft (2.8 m) straight = 9 ft (2.8 m)
System length = 14 ft (4.3 m)
Non-Vented (recirculating) Installations Through the
Soft/Cabinet
If it is not possible to vent cooking fumes and vapors to
the outside, the range hood can be used in the non-vented
(recirculating) version, using a charcoal lter. Charcoal Filter Kit
is available from the dealer or an authorized parts distributor.
