Duplex 766 Flue Tee with Cleaning Door

Duplex 766 is a flue tee with cleaning door in 120–200 mm.

Seams are welded, not folded. A folded seam is the first thing to open when a flue gets hot enough to move.

Every run needs one cleaning point per bend — plan for it now, because a sweep will insist on it later. The door hinge is adjustable, which is what keeps the seal tight in year eight.

Care

Sweep once a season and check the clamp bands after the first winter — steel moves and bands loosen.
