To Turn the Boiler On
Sealed Water Systems
Warning
A sealed water system must be filled and
pressurised by a competent person.
Only light the boiler when you are sure that the
system and boiler have been filled and pressurised.
The pressure gauge should show at least 0.7bar,
anything less than this figure could indicate a leak
and you MUST contact your installation/servicing
company.
If there is any doubt about the boiler being full of
water consult your installation/servicing company.
All Systems
Turn the electrical supply on to the boiler and
check that any remote controls are set to your
requirements (refer to manufacturer's instructions for
these items).
Remove the controls tray by withdrawing it
forward.
Turn the boiler thermostat knob clockwise to any
position between MIN and MAX , see
diagram 2.
The maximum setting is about 82°e (180°F).
The boiler lighting operation is now automatic as
follows:
The fan operates, followed by an ignition spark
until the pilot is lit. When the pilot is alight the
ignition switches off and the main burner lights.
The flames can be seen through the viewing
window.
The main burner will remain alight until switched
off by the boiler thermostat or other remote control.
If the boiler thermostat is turned Off, by hand, wait
at least 30 seconds before turning on again.
When the boiler goes off, both the pilot and main
burner go out
The automatic lighting sequence will operate again
when heat is required.
Refit the controls tray.

Protection Against Freezing
If the boiler is to be out of use for any long
period of time during severe weather conditions we
recommend that the whole of the system, including
the boiler, be drained off to avoid the risk of
freezing up. Make sure that, if fitted, the
immersion heater in the cylinder is switched off.
If you have a sealed water system contact your
installation/servicing company as draining, refilling
and pressurising must be carried out by a competent
person.
