User Indicator Lights
Identify the lights be reference to diagram 3.
The Orange - Mains light - shows that the electrical supply to
the boiler is on.
The Green - Running light - shows that the boiler is working
normally, in either the central heating or hot water modes.
If the Red - Low Central Heating water pressure light

central heating system.
During this time the red light will continue to flash and the
boiler will not work.
If this happens you MUST call your installation or
servicing company.

and pressurised by a competent person.
Only operate the boiler when you are sure that the system has
been filled and pressurised. Check this by looking at the pressure

the external isolator.
8. Set switch “C”, clock/timer (if fitted) and any remote controls

the appliance to operate momentarily, this will be indicated by the
pump starting and the fan speed increasing. This is quite normal.
Central Heating Selector Switch
For central heating set switch “C” to “On” as shown in diagram 3.
The main burner will light to provide central heating.

the burner flame will increase in size and priority will be given
to hot water. When the hot water tap is closed, the main
burner flames will decrease in size but will remain alight until
the boiler controls or any heating controls switch it off.
For domestic hot water only, set switch “C” to “Off”, as shown
in diagram 3.

tap is opened and go out when the tap is closed.
Which ever position switch “C” is in domestic hot water will
be available.
