aIr preSSUre SWItCH

Regulate the air pressure switch after first carrying out all the other
burner adjustments with the air pressure switch adjusted to the start
of the scale. With the burner operating at the requested power level,
slowly turn the central screw clockwise until the burner locks out.
Then give the screw a half-turn anti-clockwise and repeat burner
start-up to check for proper operation. If the burner locks out again
give the knob another half-turn.

IonIZatIon CUrrent

The minimum current needed to run the apparatus is 3µA.
The burner provides a significantly higher current and therefore
does not normally require any checks at all. Should however, the
ionisation current need to be measured a microammeter must be
connected in series to the ionization electrode lead by opening the
connector "C" as illustrated in the figure.
