boiler operating range, it is necessary to minimise the amount of excess air that passes through the boiler. This has resulted in the greater use of gas valves that control the ratio of gas to air. The valve has proved especially useful in modulating appliances where direct control of the fan has enabled a simple control over the gas pressure and combustion over a wide range of modulation, typ

modern gas-fired condensing boilers, this procedure cannot be used because they use a different type of gas valve even though they may be similar in appearance. This Technical Bulletin describes the air/gas ratio valves that are found on many condensing boilers and highlights the differences between these and standard gas valves. Over recent years, legislation in the United Kingdom has
