Abstract
Chimney cap unit for extinguishing a starting chimney fire, comprising a part which greatly but not completely restricts the draught during the fire in the flue, and a part which regulates the outflow of the remaining flue gas stream through the normal flue, in such a way that after a chimney fire the throughflow aperture is partially restored, so that no counterflow, which could result in flue gases entering the living-room, can occur in the flue.
