Streamline 169 Twin-Wall Insulated Pipe, 500 mm

Sections of Streamline 169 push together in the direction of flow, so condensate runs back into the fire and not down the wall.

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. Firebricks and baffles are wear parts — they are listed as spares and take ten minutes to change.

Care

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