GENERAL DIAGRAM FOR TWO-STAGE L.P.G. PRESSURE REDUCTION
Rev.26/05/2004
FOR BURNER OR BOILER
AIR PRESSURE SWITCH
Regulate the air pressure switch after fi rst 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 1,5 µ for
DLG 9.. and 3 µA for LME 2...
The burner provides a signifi cantly 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 fi gure.
