To Light the Boiler
WARNING. Sealed Systems
A sealed water system must be filled and pressurised by a
competent person.
Only light the boiler when you are sure that the system has 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 all
remote controls are calling for heat.
To Turn the Boiler On
Remove the controls cover, by withdrawing it forward and off,
see diagram 1.
Turn the control thermostat knob clockwise to any position
between MIN and MAX. The maximum temperature setting is
about 82
o
C (180
o
F), see diagram 1.
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 system switches off and
the main burner lights. The flames can be seen through the
viewing window, see diagram 1.
The main burner will remain alight until switched off by the
control thermostat or any remote control.
If the boiler is switched OFF, by hand, wait at least 30 seconds
before switching on again.
When the boiler switches off, both the pilot and main burner go
out.
The automatic lighting sequence will operate again when heat
is required.
Refit the controls cover.
To Turn the Boiler Off
For short periods, turn the control thermostat knob anti-clockwise
to “O” Off. To relight, turn the control thermostat knob to any
position between “MIN” and “MAX”.
For longer periods, turn the control thermostat knob fully anti-
clockwise to “O” Off and switch off the electrical supply to the
boiler.
To relight follow the lighting sequence given above.
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.
