3. Outdoor venting methods
(for outdoor venting through the roof or
wall only).
The hood is equipped with a transition “duct set” for exhausting air
outdoors. Vent work can terminate either through the roof or wall. To vent
through a wall, a 90 degree elbow is used.
IMPORTANT:
- Vent system must terminate outdoors (through roof or side wall).
Example 1. Vertical roof venting
Example 2. Horizontal wall venting

- Do not terminate the vent system in an attic or any other enclosed
area.
- Use only metal/flexible aluminum vents.
- Never use plastic vents.
- Always keep ducts clean to ensure proper air flow.
- NEVER exhaust air or terminate duct work between walls, crawl
spaces, ceilings, attics or garages. All exhaust must be vented to the
outdoors.
- Use caulking to seal exterior wall or roof opening around the cap.
- Do not use 10.2 cm (4 in.) laundry-type wall caps.
