Definitions
- the invention is based on exhaust gas routing according to the preamble of claim 1.
- the exhaust gas duct knows an exhaust duct with a side opening, through the backlog of exhaust gases into the installation room of the heater or air can enter the exhaust duct.
- the opening is there spaced from a base plate of the exhaust duct in a side wall of the Exhaust duct arranged and provided with a flap, which by the pressure of the back-up exhaust gas is pivotable.
- the device according to the invention with the features of claim 1 has the advantage that the effective opening cross-section of the side openings at the respective load or operating state of the heater is adjusted. So that will on the one hand, the inflowing exhaust gas before entering the exhaust gas discharge at least in lower power range of the burner less diluted and cooled, which the heat exchanger for a higher heat extraction from the combustion gas can be interpreted. On the other hand, one continues to come to the safety-related Requirement that in the event of a backflow of the exhaust gases, these pass through the side openings can exit into the installation room of the heater. The on the lower edges of the Side walls of the flue shaft hinged flaps allow easy control of the exiting exhaust gas.
- the movement of the flaps when the exhaust gases flow in is a modified embodiment in a simple manner and Way thereby prevents the flaps by stops in be locked in one direction.
- the exhaust gas duct according to Figures 1 and 2 has one box-shaped shaft 10, the two side walls 12 are arranged inclined to one another and its top wall 14 carries a connecting piece 16 for a chimney pipe.
- the two End walls 18 of the shaft 10 are opposite the Side walls 12 extended downwards and there on the Base plate 20 of a trough-shaped support part 22 connected.
- On the support part 22 is a bottom plate 20 passing through connectable to the outlet of an exhaust fan Exhaust pipe 24 offset to the connecting piece 16 attached.
- the in the shaft 10 protruding end portion 26 of the Exhaust pipe 24 is slightly curved and its Mouth 28 is arranged so far above the base plate 20 that there is a negative pressure in the lower when the exhaust gas flows Area 30 of the shaft 10 forms.
- the exhaust gas is in the lower Output range of the burner less cooled than in the upper one Power range so that the standardized minimum value of Exhaust gas temperature when entering the chimney with certainty is observed.
- the flaps 36 according to Arrow b pivoted outwards and thereby the Outlet openings 32 for unimpeded passage of the Exhaust gas released into the installation room.
- Both embodiments of the described exhaust gas routing can advantageously be designed and designed so that a connection to the fireplace both upwards and downwards can be done in the back. If the parts group is not higher is designed as a connecting bend, the usual Connection dimensions (gas, water, chimney) even without conversions in the Device are observed.

Claims (4)
- Abgasführung für ein Heizgerät mit einem insbesondere gebläseunterstützten Brenner, mit einem Seitenwände aulweisenden Abgasschacht (10) und mit seitlichen Öffnungen (32), durch die rückstauendes Abgas in den Aufstellungsraum des Heizgeräts oder Luft in den Abgasschacht (10) treten kann, wobei die seitlichen Öffnungen (32) durch bewegliche Klappen (36) gesteuert und die Klappen (36) in Öffnungsrichtung durch den Druck des rückstauenden Abgases verschwenkbar sind, dadurch gekennzeichnet, dass die seitlichen Öffnungen (32) zwischen den unteren Rändern (31) der Seitenwände (12) des Abgasschachtes (10) und einer im Abstand darunter angeordneten Bodenplatte (20) gebildet sind, und dass die beweglichen Klappen (36) an den unteren Rändern (31) der Seitenwände des Abgasschachtes (10) angelenkt sind.
- Abgasführung nach Anspruch 1, dadurch gekennzeichnet, dass ein das Abgas in den Abgasschacht (10) einleitendes Rohr (24) soweit stromab der Bodenplatte (20) ausmündet, dass sich über dieser bei Aufstrom des Abgases ein die Klappen (36) im gewünschten Sinn verstellbarer Unterdruck ausbildet.
- Abgasführung nach Anspruch 1, dadurch gekennzeichnet, dass die Klappen (36) aus einer den Strömungsquerschnitt bei Minimalleistung des Brenners stark drosselnden Mittelstellung heraus durch rückströmendes Abgas nach außen und durch den bei Aufstrom entstehenden Unterdruck nach innen verschwenkbar angeordnet sind.
- Abgasführung nach Anspruch 1, dadurch gekennzeichnet, dass Anschläge (40) vorgesehen sind, die eine Bewegung der Klappen (36) bei Aufstrom des Abgases verhindern.
