Abstract

Gas-Heizgerät, insbesondere für Wassererhitzer, mit einem Vormischbrenner, der in einzeln aktivierbare Brennzonen (22) aufgeteilt ist, denen die Verbrennungsluft gemeinsam durch ein Gebläse und das Brenngas geregelt über je eine Einzelleitung zugeführt sind. Es wird vorgeschlagen, daß die Verbrennungsluft wie das Brenngas jeder Brennzone (22) über einen Einzelkanal (24) zugeführt ist, daß in einer alle Brenngas-Einzelleitungen (58) speisenden Hauptleitung (32) ein vom Luftvolumenstrom gesteuerter Gas/Luft-Verbundregler (52) eingebaut ist und daß in den einzelnen Brenngas-Einzelleitungen (58) Auf/Zu-Ventile (64) zum Zu- und Abschalten der Gaszufuhr zu den Brennzonen (22) angeordnet sind.

Figure 00000001
Gas heater, in particular for water heaters, with a premix burner, which is divided into individually activatable combustion zones (22), to which the combustion air is fed jointly by a fan and the fuel gas is supplied via a single line each. It is proposed that the combustion air, like the fuel gas, is fed to each combustion zone (22) via a single channel (24), that in a main line (32) feeding all fuel gas individual lines (58), a gas / air compound controller (52 ) is installed and that in the individual fuel gas individual lines (58) on / off valves (64) for switching on and off the gas supply to the combustion zones (22) are arranged.
