Abstract (en)
[origin: EP0949455A1] The heating unit has a bypass valve (7) with a solenoid operating unit (8), which is coupled with a fan (9), is arranged in a bypass to the fuel supply line (5), upstream from burner stages (1,2). Thus when increased heating power is required, an increased fuel supply to the burner stages results by the opening of the bypass valve by the solenoid. The bypass valve is only operable, if the fan is in operation. The throttle element is arranged in the fuel supply line, before its branching to the burner stages, outside from the bypass.
