This step may need repeating a few times to purge any air trapped in the pilot line
and valve assembly, if this is the case press and hold enter for 2 seconds to reset
the LMV and restart this step.
Once the pilot flame is lit look through the burner flame observation glass on top
of the boiler to check the flame visually for stability. The flame should be steady
and constant with no burn back past the burner brick. Use the mono-meter to
measure the pilotline gas pressure
while the flame is present by attaching the sensor to the output pressure tap of the
pilot valve. The pressure here should be 17-20 mbar; 20 mbar is preferable to
provide a strong pilot flame. If the pressure here is outside the desired range use
the pilot valve pressure regulator adjustment to set the pilot pressure within range.

The burner may now be progressed to igniting the main flame on P0 by pressing
the + key. If the flame fails to ignite and the standard flame failure error is displayed
hold the enter key for 2 seconds to reset the LMV and repeat step 16. Again, this
may need repeating a few times to purge the gas line and valve assembly. If the
main flame still fails to ignite but shows an attempt to ignite when viewed through
the burner flame observation glass, try increasing the opening of the fuel and air
damper valves in small increments for P0 in the ratio2F:1A.
Once the flame is established use the burner flame observation glass to check
stability. If the flame appears weak increase the opening of the air and fuel damper
valves in the ratio 2F:1A until the flame appears strong. If any adjustments are
made at this point repeat steps 16 and 18 to confirm ignition of main flame from
pilot.
