Kitchen Ventilation: Planning a Chimney and Fresh-Air Route
Plan extraction, duct path, make-up air and service access together.
Start with your home and household
Confirm the hood specification, duct route, bends, external outlet and cleaning access with the installer. Consider how replacement filters and maintenance will be reached. Add the relevant measurements and product requirements to the room brief, then compare the proposed layout at full scale before ordering.
A common mistake to avoid
A powerful hood cannot correct a badly routed or blocked duct. Do not seal every source of replacement air. Confirm the final choice against the actual site, the manufacturer's guidance and the people who will use the room.
Before you finalize
- Measure the room and note fixed services, openings and clear walking routes.
- Compare material samples and written specifications, not just names or images.
- Record the agreed scope, budget, installation details and maintenance needs.
