DIMENSIONS
RANGE HOOD - 36" (91.4 CM) AND 48" (121.9 CM)
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 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.

Venting Methods
Typical Internal Blower Motor System Venting Installations
A 10" (25.4 cm) round vent system is needed for installation (not included). The hood exhaust opening is 10" (25.4 cm) round.
NOTE: Flexible vent is not recommended. Flexible vent creates back pressure and air turbulence that greatly reduce performance.
Vent system can terminate either through the roof or wall. To vent through the wall, a 90° elbow is needed.
