Abstract (en)

The method involves operating a fan (3) for a predefined minimum time at a defined, preferably maximum speed or power before reducing its speed to the starting value and then slowly increasing it up to a defined pressure value. A temperature correction function is computed from primary heat exchanger (13) feed and return temperature measurements and used to correct the computed revolution rate used to determine the operating characteristic.

Abstract (de)

Verfahren zur Anpassung eines brennerbeheizten Heizgerätes (23) an ein diesem zugeordneten Luft-Abgassystem (24), das mit einem Gebläse (3) versehen ist, wobei das Heizgerät (23) eine in Abhängigkeit vom jeweiligen Wärmebedarf arbeitende Gasregeleinrichtung (7, 18) und eine Druckmeßstelle (14) aufweist, die mit der Gasregeleinrichtung (7, 18) in Verbindung steht, die die Gaszufuhr erst bei Erreichen eines bestimmten Druckwertes im Luft-Abgassystem (24) freigibt. Um einen optimalen Betrieb zu ermöglichen, ist vorgesehen, daß bei einer ersten Inbetriebnahme unter festgelegten Temperatur- und Betriebsbedingungen die Drehzahl des Geläses (3) ausgehend von einer Startdrehzahl, bei der der für die Freigabe der Gaszufuhr vorgesehene Druckwert auch bei kürzester Länge des Luft-Abgassystems (24) nicht erreicht wird langsam gesteigert wird bis der vorgesehene Druckwert erreicht ist, wonach aus der Drehzahl, bei der dieser Wert erreicht wurde, ein Korrekturfaktor ermittelt wird, mit dem aus Standardkennlinien Betriebskennlinien errechnet werden, nach denen die Gasregeleinrichtung (7, 18) arbeitet. <IMAGE>
