GENERAL DIAGRAM FOR TWO-STAGE L.P.G. PRESSURE REDUCTION FOR BURNER
OR BOILER
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 1,5 µ for DLG
9.. and 3 µA for LME 2...
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.
