Vent system must terminate to the outside (roof or side wall), Be careful not to bend duct as this
will reduce the exhaust effectiveness of the rangehood.
Do not terminate the vent system in an attic or other enclosed area.
Do not use 102 mm laundry-type wall caps.
Use metal/Aluminum vent only. Rigid metal/aluminum vent is recommended.
Do not use plastic vent.
Always keep the duct clean to ensure proper airflow.
Calculate the following figures before installation:
1. Distance from the floor to the ceiling.
2. Distance between the cooking surface to the range hood.
3. Height of hood and duct cover.
For the most efficient and quiet operation:
1. It is recommended that the range hood be vented vertically through the roof through 200
mm round metal/aluminum vent work.
2. The size of the vent should be uniform.
3. Use no more than one 90°elbow.
4. The vent system must have a damper. If roof or wall cap has a damper. Do Not use damper
supplied with the range hood.
5. Use duct tape to seal all joints in the vent system.
6. Use caulking to seal exterior wall or roof opening around the cap.
