 extract the sensor 2);
 clean the glass cover from any dust that may have accumu-
lated.
 Be extremely careful while troubleshooting the
detector; line voltage is present on some of the

Flame signal measurement

Check the flame signal through the parameter 954, as indicated in
Fig. 40. The displayed value is expressed in percentage.
The value during the operation must be higher than 24%. If at the
burner start-up the value is higher or equal of 18%, the burner locks
out due to the extraneous light.
For further and specific information, please refer to the specific in-
struction manual.
The display (Fig. 40) shows parameter 954: flashing on the left. On
the right, the flame's intensity is displayed as a percentage.
Example: 954: 0.0
