Vent system must terminate to the outdoors.
Do not terminate the vent system in an attic or other enclosed
area.
Do not use a 4" (10.2 cm) laundry-type wall cap.
Use metal vent only. Rigid metal vent is recommended.

The length of vent system and number of elbows should be
kept to a minimum to provide efficient performance.
For the most efficient and quiet operation:
Use no more than three 90° elbows.
Make sure there is a minimum of 24" (61.0 cm) of straight
vent between the elbows if more than 1 elbow is used.
Do not install 2 elbows together.
Use clamps or duct tape to seal all joints in the vent system.
The vent system must have a damper. If roof or wall cap has a
damper, do not use damper supplied with the range hood.
Use caulking to seal exterior wall or roof opening around the
cap.
The size of the vent should be uniform.
Cold Weather Installations
An additional back draft damper should be installed to minimize
backward cold air flow 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 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.
Venting Methods
This canopy hood is factory set for venting through the roof or
wall.
A 3 " x 10" (8.3 x 25.4 cm) rectangular vent system is needed for
installation (not included). The hood exhaust opening is 3 " x
10" (8.3 x 25.4 cm). Vent system can terminate either through the
roof or wall. To vent out of the top of the range hood and through
a wall, a 90° elbow is needed. See "Install Range Hood" section
for details for installing the damper.
NOTE: Flexible vent is not recommended. Flexible vent creates
back pressure and air turbulence that gently reduce performance.
