BV-RH801 USER MANUAL
VENTING METHODS
1. This range hood is 6” top venting through the roof or wall.
2. Vent work can terminate either through the roof or wall as shown
below.
3. A minimum of 6” round duct (purchase separately) or 3-1/4 x 10”
rectangular duct (purchase separately) must be used to maintain
maximum airow efciency.
4. Always use rigid or semi-rigid type metal/aluminum ducts if avail-
able to maximize airow.
5. Decide the location of the venting pipe from the hood to the out-
side.
6. A straight, short vent run will allow the hood to perform more
efciently. Try to avoid as many transitions, elbows, and long run as
possible. This may reduce the performance of the hood.

walls, crawl spaces, ceiling, attics or garages. All exhaust must be
ducted to the outside.
2. Fasten all connections with sheet metal screws and tape all joints
with certied Silver Tape or Duct Tape.
3. Use caulking to seal exterior wall or roof opening around the cap.
