To Light the Boiler
WARNING: Sealed Systems
Do not operate the boiler wthout water.
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.
It should be noted that this is a fan flue appliance and fan operation
may be heard.
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.
For the position of the serial number, see diagram 1.
