Abstract (en)

[origin: EP0744582A1] The device comprises a heat sensitive element (10). This sensor detects the flow back of combustion products from the outlet flow in the apparatus draw chimney (3). The heat sensor is positioned outside the chimney behind the apparatus at the level of an opening (8) in the rear face (9). Fresh air normally is induced in this region. The opening is in the extension of a central diverter (7) located inside the chimney casing directly below the exhaust gas duct (4). The central diverter has the shape of a longitudinal small dish whose concavity is upwards.
