01: Failure to ignite; To re-set turn mode selector switch to re-set position
for approximately 10 seconds, then back to original position.
If during the ignition attempt period (10 secs approx.) the boiler fails to light, the ignition
control circuit will go to lockout. This is indicated by the status LED flashing red accompanied
by a flashing error code 01 shown in the temperature indicator. The gas valve is de-energised,
but leaves the fan and pump running for approximately 2 minutes after lockout.
In the event of the boiler going to lockout turn the mode selector switch to the reset position
for approximately 10 seconds, then back to the original position. The two main causes of
the boiler going to lockout during commissioning are electrical supply polarity reversed, or air in
the gas supply. Check polarity and that the gas supply is completely purged of air, and that
gas is reaching the boiler, then repeat.
A. Checking Burner Pressures
The pressure reading for maximum rate should be for the linea 28 (N/G) 10.1mbar (plus or minus 1.0mbar)
If the pressure is wrong it should be adjusted whenever the maximum rate is adjusted, check and adjust
the minimum rate too)
B. Reduce the domestic water flow rate to approx. 3-4 litres/min, turn the domestic control knob
slowly to minimum. The boiler output will reduce to the minimum setting. If low flame
cannot be established in this way, turn off the electricity supply and remove one of the grey
wires connecting to the modulator coil on the front of the gas valve. Switch on the electricity
supply. The boiler will now light at the minimum setting. When low flame is established, the pressure
reading should be for the linea 28 (N/G) 1.3mbar (plus or minus 0.13mbar)
If it is different adjustment should be made in accordance with the instructions.
