Gas heated appliance with a device for controlling the heating

摘要

The heating system has a gas powered boiler with a burner (4) that is fed from a supply line via a valve unit (5) that is adjusted, dependent upon the type of gas used. The unit has a movable two-way valve element that switched between two different gas supplies to different gas nozzles in the burner that are specifically designed for the gases. The valve is coupled to the boiler controller (2).
