8 - Adjustment of the gas pressure, gas rate and soft-
light, partial load and full load.
9 - Check of the heating safety systems:
-
safety device for maximum temperature (overheat
thermostat);
-
safety device for maximum pressure (safety
valve).
10- Check of the gas safety systems:
-
safety device for lack of gas or flame ionisation
(detection electrode).
11- Check of the electrical connection (ensure it
complies with the instructions in the manual).
