Abstract (en)
A heating system comprises a diaphragm operated fuel valve (100) for supplying fuel to a burner (40) with said diaphragm (124) forming a wall portion of a control chamber (118) which is directly connected to a pressure sensing port provided at a venturi nozzle (106). This nozzle is located in the stack (80) and derives a pressure signal corresponding to the flow rate of combustion air provided by a blower (60).
