Lighting your Boiler
Before lighting your boiler, ensure that :
• There is sufficient fuel in the supply
tank
• All fuel supply valves are open.
• The water supply is on
• The electricity supply to the boiler is
off
• The Boiler On/Off switch is set to
OFF
• The white pointer on the pressure
gauge is not below the red pointer
• The room thermostat is at the
desired setting
• The timer or programmer is correctly
set
Switch on the electricity supply to the
boiler.
Set the On/Off switch to ON. Refer to
Figure 2.
The boiler will light automatically to heat
the water stored in the boiler. If the
Programmer or Timer is set to a heating
‘on’ period and the room thermostat is
‘calling’ for heat, the boiler will continue
to run to provide central heating, after
the store reaches temperature.
Once the store has reached
temperature, if a hot tap is opened the
boiler will supply hot water.
Turning off your Boiler
For short periods - Set the On/Off
switch to OFF. Refer to Figure 2.
To re-start the boiler, simply set the
switch to ON.
For long periods - Set the On/Off
switch to OFF and switch of the
electricity supply to the boiler. If
required, the fuel supply valve may be
closed and the water and electrical
supplies turned off at the mains. To re-
start the boiler, refer to the full lighting
instructions above.
