3. INITIAL LIGHTING
If turning on the boiler for the first time carry out the following steps:
  Check that the electrical supply to the boiler is ON at the
external isolator.
  Ensure all hot taps are closed.
  Set any remote controls as required.
  Turn the CH and DHW controls to the minimum setting. Switch on
the appliance at the on/off switch on the control panel. The boiler
will then be in the STANDBY mode.
  Check the heating system pressure displayed in the RH lower
corner of the display. This should read at least 1.0 bar. A sealed
pressurised system must be filled by a competent person.
Only operate the boiler when you are sure that the system has been filled
and pressurised. If you are in any doubt about the boiler being filled with
water contact your installer.
4. OPERATION OF CENTRAL HEATING
In order to turn on the central heating and adjust the temperature, turn the
control knob P1 to the desired setting between off and max 82°C.
When the control knob is turned the central heating water temperature will
flash and indicate the new temperature setting.
After a delay of 5 seconds the display will revert to a steady display of actual
central heating water temperature. This will disappear if there is no central
heating demand.
During a central heating demand the radiator symbol and the central heating
water temperature will be illuminated on the display.
If central heating is not required for any extended period turn the control
knob P1 fully anti-clockwise to the off position. In this position the “heating
off “ symbol will be displayed, the domestic hot water and frost protection
will still be active. This is also the “summer mode”.
5. OPERATION OF DOMESTIC HOT WATER
The domestic hot water temperature is adjustable between 30°C and 65°C
by the control knob P2.
When the control knob is turned the DHW water temperature will flash and
indicate the new temperature setting.
After a delay of 5 seconds the display will revert to a steady display of actual
DHW temperature. This will disappear if there is no DHW demand.
During a DHW demand, the tap symbol and the DHW temperature will be
illuminated on the display.
6. PRE-HEAT BUTTON
With the pre-heat button selected the boiler is maintained in a hot condition
to enable a fast response to any DHW demand. When selected, PRE-HEAT
will be illuminated on the display.
If required this can be selected for all year round use, but will be of
maximum benefit in the summer months, or when there is little or no
demand for central heating, in which case the boiler would become cold
without the pre-heat button selected.
The pre-heat function has a built-in intelligent function that will turn itself off
if there is no DHW demand for a 24 hour period. If previously selected, once
DHW water has been drawn off, the function will automatically re-enable.
7. RESET BUTTON
Should a fault occur this button can be pressed to reset the controls and
initiate a new start up sequence.

8. FLAME LOSS
Should the flame signal be lost 5 times in any 4 minute period then the
boiler will lockout and an error code will be displayed in the centre of the
display. Pressing the reset will enable the boiler to relight.
If the fault recurs, turn off the boiler and consult a CORGI registered
installer.
9. BOILER OVERHEATING
In the event of the boiler overheating the boiler will lockout and an error
code will be displayed in the centre of the display. Pressing the reset will
enable the boiler to relight.
If the fault recurs, turn off the boiler and consult a CORGI registered
installer.
10. WATER SYSTEM PRESSURE
The water system pressure is shown in the bottom right hand of the
display.
If the pressure drops below 1.0 bar it will begin to flash indicating the
system needs to be topped up by a competent person.
If the pressure continues to drop and reaches 0.6 bar, an error code
will appear in the centre of the display and all heat demands will be
blocked. This may indicate a leak and the system should be checked
before being re-pressurised.
11. CONDENSATE DRAIN
The condensate drain must not be modified or blocked.
Blockage of the condensate drain caused by debris or freezing, can
cause the boiler to lockout.
If freezing is suspected and the pipe run is accessible, then an attempt
to free the obstruction by pouring hot water on to the pipe may be
made. If this fails to remedy the problem, the assistance of a CORGI
registered installer should be sought.
12. SERVICE & MAINTENANCE
It is recommended that a full maintenance check be carried out
annually on the appliance. It is also recommended to take out a further
service agreement on the expiry of the guarantee period.
You can obtain further information on this from your gas supplier.
The appliance should be checked /serviced by a CORGI registered
installer.

by telephone on 01256 372400.
13. ESCAPE OF GAS

delay.
