Alpha boiler manuals pdf Download
The Alpha Range of boilers are wall mounted, fan assisted room-sealed combination boilers. Heat output is controlled by a modulating gas valve. The boilers, providing both central heating and domestic hot water at mains pressure, are designed for use with a fully pumped, sealed and pressurised heating system using only Natural Gas.
The boilers are supplied with a pump, diverter valve, pressure relief valve, expansion vessel and pressure gauge fully assembled and tested. As supplied, the Alpha 240E and 240P boilers will automatically modulate to provide central heating outputs between 9.3 and 23.3 kW (31 700 and 79 500 Btu/h). The Alpha 280E and 280P boilers will provide central heating outputs between 9.3 and 28.0 kW (31 700 and 95 500 Btu/h).
The maximum output available for domestic hot water is 23.3 kW (79 500 Btu/h), capable of providing 9.5 litres/min with a temperature rise of 35°C for the Alpha 240E and 240P boilers, and 28.0 kW (95 500 Btu/h), capable of providing 11.4 litres/min with a temperature rise of 35°C for the Alpha 280E and 280P boilers.
