2.22 INITIAL LIGHTING

THE DISPLAY

The user control has one display to inform the user about 

the status of the boiler. The LCD Display shows the status 

of the flame.  If no flame is detected the flame symbol 

will not be visible. When the flame is detected the flame 

symbol will be visible permanently.
Below is a list with display function in normal operation.

0 0

 

Standby, no demand for heat present.

 

Boiler is active for central heating.

  Boiler is active for domestic hot water.

P H

 

Boiler is heating up the plate heat exchanger.

F P

 

Boiler is active for boiler frost protection.

  Boiler is in lockout for a specific error.  Display will 

show a number after the “ ” to indicate which error is 

detected.

F

 

Boiler has a fault for a specific error.  Display will show a 

number after the “ ” to indicate which error is detected.

Note:

  Boiler frost protection - boiler operates if the 

ambient temperature is below 5ºC until it reaches 19ºC. 

1. 

Check that the system has been filled to the required 

pressure and that the boiler is not airlocked. Ensure 

the automatic air vent cap is open. 

Note.

It is important the burner is not operated before the system is fully vented of 

air, refer to Section 2.25, point 4. If it is necessary to operate the appliance 

pump to assist venting of the air this must be done with the gas service cock 

turned off.

2.

  Refit the boiler front panel. Refer to Section 3.2.

3.

  Check that the drain cock is closed and that the CH and DHW isolating 

valves (G, J and K) are OPEN.

4.

  Check that the electrical supply is OFF.

5.

  Check that the boiler mode knob (C) is off.

6.

  Check that the gas service cock (I) is OPEN.

7.

  Slacken the screw in the inlet pressure test point (H) and connect a gas 

pressure gauge via a flexible tube.

 

8.

  Switch the electricity supply ON and check all external controls are calling 

for heat.

Note. The boiler incorporates a fan overrun cycle which 

MUST NOT be prematurely interrupted by isolation of the 

mains electricity supply.

CENTRAL HEATING

9.

  Set the CH temp control (B) to “MAX” and turn the mode knob (C) to  

’. The boiler control should now go through its ignition sequence 

until the burner is established.

10.

 If the boiler does not light then after 5 attempts the boiler will lock 

out and display fault code 

L 2

.

  Restart the boiler (Refer to Section 2.24).  The boiler will repeat its 

ignition sequence.  If restart occurs 5 times within 15 minutes then   

LC

 will be shown.

 

When the burner is established the ‘ ’ will be shown on the display 

with the ‘

’ indicating central heating operation and the current flow 

temperature shown in the 2 digit display.

DOMESTIC HOT WATER

11. 

With the boiler firing, set the DHW Temp Knob (A) to maximum 

and fully open a DHW tap.

  The boiler should continue to run and the display should change 

from showing ‘ ’ to ‘ ’.

12.

 Ensure that with the boiler operating the dynamic gas pressure is 

able to obtain maximum output. Refer to Table 2.

 IMPORTANT

  The  gas  input  to  the  burner  is  regulated  by  the  gas  valve 

according to the air flow produced by the fan. It is NOT user-

adjustable. Any interference to sealed settings on the gas valve 

will adversely affect operation and render our warranty void.

 

For additional gas supply info refer to “Gas Supply” on page 12.

13.

 Turn off the DHW tap.
