15 - USE
Loc 20 Flame lost three times Check: that the ionisation current is at a value of more
than 4 (follow the procedure in section 16.12)
Check: that the flue gas outlet is suitably protected
from blockages caused by gusts of wind
If the ionisation current is not more than 4 the CO2 must
be checked (follow the instructions in section 14.8) and
reset to the correct value, check the ionisation spark plug
and replace it if necessary, check the integrity of the wires
in the ionisation current electrical circuit.
If the flue gas outlet is positioned on a vertical wall it
must be protected by an anti-wind grill; if the flue gas
outlet is positioned on the roof, check that it isn’t in a
area where there is flowback, and that any anti-wind
chimney that may be provided is really effective.
