MANUAL BURNER OPERATION INSTRUCTIONS
Combustion may be checked throughout the entire modulation
range by means of manual adjustments to operation. Use the
modulation connector (B) in the figure, supplied with the burner.
After disconnecting the 4 pole socket (A) taking signals from the
thermostat line or the RWF 40 regulator, insert the connector in its
place (B). Use the + button to increase the flow of gas and air or
the - button to decrease.
After completing the check, plug the 4 pole plug (A) back in to restore
automatic modulation.
IONIZATION CURRENT
Minimum current required to enable the unit to work is 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.
