boiler is attached to the reverse of

About your Boiler
The boiler is fully automatic once
switched on, providing central heating
(and also heating your domestic hot
water if you have a hot water cylinder
fitted). The boiler has a 'mains on' neon,
see Figure 1, which lights when the
boiler is switched on, but does not
necessarily indicate the burner is firing.
If your model is controlled by a remote
programmer and a room thermostat, it
will provide hot water and central
heating during the periods as set on the
programmer, when either the room
thermostat and/or the hot water
thermostat are calling.
