it works properly.
9) Check the triggering of the ionisation electrode by disconnecting
the jumper between terminals 30 and 31 on the printed circuit
board and start the burner. The equipment must run through
its cycle completely and, three seconds after the ignition flame
has formed, "lock-out". This test should also be performed
with the burner already on. The equipment should shut down
immediately when the jumper between terminals 30 and 31 is
disconnected.
10) Check the proper operation of the boiler thermostats or
pressure switches (when triggered they must stop the burner).
Check that the ignition occurs properly. In the event that the
mixer is too far forward, it may happen that the speed of the
delivery air is so high that ignition is difficult. If this happens,
move the regulator back bit by bit to a position in which ignition
occurs properly, and acquire this as the final position. With the
1 stage, it is better to limit the amount of air to the amount
st
strictly indispensable to ensure safe ignition even in the
most difficult cases.
Once the adjusting operations are completed, visually check
that the thin plate on which the bearing acts has a progressive
profile. Using the appropriate tools check also that in the
passage from the 1 to the 2
st

IONISATION CURRENT MEASUREMENT

To measure the ionisation current, remove the jumper between
terminals 30-31 on the printed circuit with the burner off. Connect
a microammeter to the terminals (with a suitable scale to have the
burner restart). Once the flame has appeared it will be possible
to measure the ionisation current, the value of which must be 3
µA to ensure the operation of the equipment. After making the
measurement, reset the jumper that has been disconnected.
