Abstract (en)

The system for the feed of gas in a gas-water heater has a valve arrangement with a first magnetic valve (17) for an ignition gas volume, and a second magnetic valve (19) for an operating gas volume. The first magnetic valve is piloted into the open position by the line (21) to the ignition and the second magnetic valve by the flame monitoring responses (22). The operating of the first magnetic valve may be tripped by the triggering of the second magnetic valve.

Abstract (de)

Die Erfindung betrifft eine Vorrichtung zum Zuführen von Gas bei einem Gas-Wassererhitzer mit einem Gasbrenner mit Flammenüberwachung, die in der Zuführungsleitung zum Gasbrenner eine Ventilanordnung aufweist, welche bei der Einleitung des Betriebes des Gasbrenners in die Öffnungsstellung steuerbar ist. Eine einfache, kostengünstige und geräuscharme Vorrichtung wird dadurch geschaffen, dass die Ventilanordnung ein erstes Magnetventil (17) für eine Zündgasmenge und ein zweites Magnetventil (19) für eine Betriebsgasmenge aufweist und dass das erste Magnetventil (17) mit der Einleitung der Zündung und das zweite Magnetventil (19) mit dem Ansprechen (22) der Flammenüberwachung in die Öffnungsstellung steuerbar sind. <IMAGE>
