NOTE: this is a guide diagram; according to the model, the position of electrodes, pilot flame, motor fan and gas
shut-off valve can vary.
Gas filter in models ADI 850 and 950:
In these models, the gas filter is supplied dismantled inside the boiler, for an
easier and safer transport.
It must be assembled once the boiler is in the installation.
The minimum gas pressure gauge is connected to the gas filter inlet.
In order to rotate the motor-fan group and take off the burner, you have to
remove first the gas filter and then proceed according to the instructions indicated
in the corresponding chapter (19.1).
