PRESSURE REDUCTION FOR BURNER OR BOILER
REV. 21/03/90
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 a low flow rate (1 flame), slowly turn the central screw
st
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 screw 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. In case, 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.
