Abstract (en)
[origin: EP1170549A2] A heat exchanger (3) heated by a burner (14) is incorporated after a water-valve in a water-switch (5) and after the gas-valves (36,44) controlled b the water-switch and by a servo valve (29). The servo valve has an interior (58) divided by a membrane into a first chamber connected to the gas-path between the two gas-valves. The second chamber is connected to the gas-path downstream from the gas-valve by means of a valve operated by an electro-magnet The membrane has a carrier supporting the valve body (37) of the gas-valve. The carrier end facing the valve body carries the valve body against the restoring force of a spring.
