Alpha CD24/32
The Alpha CD range of high efficiency condensing boilers are wall mounted, fan assisted room-sealed boilers.
The CD24C and CD32C are combination boilers providing both central heating and domestic hot water at mains pressure. The
CD24S is a system boiler providing heating only for sealed central heating systems.
The CD24C and CD24S boilers are suitable for central heating loads of between 4.9 and 25.4 kW (16 700 and 86 700 Btu/h).
The CD32C boiler is suitable for central heating loads between 6.5 and 29.8 kW (22 200 and 101 700 Btu/h).
The boilers will provide central heating (as required) during the 'on' times set on your clock (if fitted). Hot water is always
available from the Alpha CD24C and CD32C boilers whenever a hot tap is opened and takes priority over the central heating.
The burner is lit electronically.
If applicable, pull the controls panel cover forward and down to gain access to the controls.
