1 DESCRIPTION

The Alpha 240X boiler is a wall mounted, fan assisted room-sealed combination boilers, providing both central heating and
domestic hot water at mains pressure and it uses a permanent pilot for lighting the burner.

The Alpha 240X boiler is suitable for central heating loads of between 9.3 and 23.3 kW (31 700 and 79 500 Btu/h).
The boiler will provide central heating (as required) during the 'on' times set on your clock (if fitted). Hot water is always

available whenever a hot tap is opened and takes priority over the central heating.

Fig. 1

3 BOILER CONTROLS

1. CENTRAL HEATING THERMOSTAT

This thermostat controls the temperature of the water leaving the boiler for the heating system. For maximum output from the
radiators the thermostat should be left at maximum i.e. fully clockwise. If lower heating temperatures are required, turn the thermostat
anti-clockwise.

2. DOMESTIC HOT WATER THERMOSTAT

This thermostat controls the temperature of the domestic hot water leaving the boiler. For maximum hot water temperatures the
thermostat should be left at maximum i.e. fully clockwise. If lower temperatures are required, turn the thermostat anti-clockwise.

3. SELECTOR SWITCH

This control allows the boiler to provide central heating and hot water or hot water only.

4. PRESSURE GAUGE

This indicates the central heating system pressure. It should always be within the green band when cold, increasing slightly when hot.
If the pressure falls below the green band i.e. lower red area, refer to the label on the pull out panel for guidance on re­pressurising the system. Or contact your Installer to have the system checked and pressurised.

5. OVERHEAT THERMOSTAT

This thermostat automatically switches the boiler off in the unlikely event of the boiler overheating. When the thermostat
operates it turns the pilot off, and the pilot will have to be relit. Refer to the lighting instruction in section 4.
If this continually happens, contact your Service Engineer.

6. PRESSURE RELIEF VALVE

If the central heating system overheats and steam or water is discharged from the pipe connected to this valve, turn the boiler off
and contact your Service Engineer. Your Installer should have told you where this pipe terminates somewhere outside your dwelling.
