Flame lost three times
Make sure: that the ionisation current is at a value
higher than 4 (follow the procedure in section 17.12)
Make sure: that the flue exhaust is appropriately
protected from obstructions caused by gusts of wind
If the ionisation current is not over 4, you must check the
CO2 (follow section 15.8) and restore the proper value.
Check the ionisation glow plug and, if necessary, replace
it. Make sure the ionisation current electrical circuit cables
are intact.
If the flue exhaust is positioned on a vertical wall,
it must be protected by a windproof grid. If the flue
exhaust is positioned on the roof, make sure it is not
in a reflux area and that the windproof chimney, if any,
is actually efficient.

The flue exhaust sensor
temperature does not
rise when the burner
ignites
a-make sure the flue gas sensor meets the require
-
ment in section 17.14.
b - Make sure that the flue gas sensor (parameter
1006) increases the temperature when the burner
ignites.
a-If the flue gas sensor does not meet section 17.14,
it must be replaced.
b - If the temperature does not rise, replace the flue gas
temperature sensor or the command and control board.
