Abstract (en)

For such appliances there is a present requirement that the combustion air is obtained through a fan directly from outside the positioning room of the appliance. Since for a central heating installation one desires a modulating burner flame control in order to approximate the desired room temperature as continuously as possible, then the gas supply and the air supply should be mutually adapted in order to obtain a high burner efficiency. The invention achieves this by means of an air pressure membrane to which a gas pressure control membrane is mechanically coupled.
