Air Pressure Switch - baltur BTG 20 LX Notice D'instructions

GENERAL DIAGRAM FOR TWO-STAGE L.P.G. PRESSURE REDUCTION FOR BUR-
NER 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 clockwi-
se 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.
