Venting requirements
Vent system must terminate to the outside.
Do not terminate the vent system in an attic or other enclosed area.
Do not use 4 inch (10.2 cm)
Use 6 " (15.2 cm) metal vent only. Rigid metal vent is recommended. Do not use plastic or metal foil vent.
For the most efficient and quiet operation:
•Use no more than three 90° elbows.
•If an elbow is used, install it as far away from the hood’s vent motor exhaust opening as possible.
•Make sure there is a minimum of 24" (61 cm) of straight vent between the elbows if more than one elbow is used.
•Do Not install two elbows together.
•The length of vent system and number of elbows should be kept to a minimum to provide efficient performance.
•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 duct tape to seal all joints in the vent system.
•Use caulking to seal exterior wall or roof opening around the cap.
Determine which venting method is best for your application and follow “Preparation” under ”Installation steps“ on Page 5.
Venting methods
This range hood is set for venting to the outside. For
Vent system needed for installation is not included. Use 6" (15.2 cm) round vent.
Vent system can terminate either through the roof or wall. To vent through a wall, a 90° elbow is needed.
The 6" (15.2 cm) round vent system length should not exceed 35 ft. (10.7 m).

Calculating the vent system length
To calculate the length of the system you need, add the equivalent feet (meters) for each vent piece used in the system.
Vent piece | 6" (15.2 cm) round |
45° elbow | 2.5 feet |
| (0.8 m) |
90° elbow | 5.0 feet |
| (1.5 m) |

2ft.
(0.6 m)
Maximum length | = 35 ft. (10.7 m) | |||
1 | — 90° elbow | = | 5 ft. | (1.5 m) |
8 ft. (2.4 m) straight | = | 8 ft. | (2.4 m) | |
1 | — wall cap | = | 0 ft. | (0 m) |
system length | = 13 ft. | (3.9 m) | ||
Note: Flexible vent is Not recommended.
If it is used, each foot of flexible vent used is equivalent to two feet
(61 cm) of straight metal vent when calculating the vent system length. (Example: A flexible elbow equals two standard elbows.)
