MANUAL MODE BURNER INSTRUCTIONS
Combustion control can be carried out over the whole modulation
range with the manual mode operation. For this use modulation
connector (B) in the diagram, which is provided with the burner
as standard. After disconnecting the 4-pole plug (A) which takes
the signals from the thermostat or the RWF 40 adjustor, insert the
connector in position (B). Use the + button to increase the gas and
air supply or - to reduce it.
After the check, put the 4-pole plug (A) back in so as to reset au-
tomatic mode modulation.
IONISATION CURRENT MEASUREMENT
To measure the ionisation current, remove the jumper between
terminals 30-31 on the printed circuit with the burner off (see
diagram). Connect a microampmeter to the terminals (with a suitable
scale to have the burner restart). Once the flame has appeared it
will be possible to measure the ionisation current, the minimum
value of which to ensure the working of the equipment is shown in
the specific wiring diagram. After making the measurement, reset
the jumper that has been disconnected.
