fi
lter and clean it.
3) Replace the
fl
ame control the circuit.

5) The electrodes short circuit to ground because
they are dirty or the insulation is damaged.
1) Verify the entire circuit.
2) Replace it.
3) Replace it.
4) Reposition them at the correct distance (see
Fig. 15).

fi
rmed
with an unpleasant odour,
black smoke or
