If the probe or electrode is not correctly positioned, you must:

Once this operation (if necessary) has been carried out, fix the
flange 11)(Fig. 11) to the boiler plate, interposing the insulating
gasket 9)(Fig. 11) supplied.
Use the 4 screws supplied, with a tightening torque of 35 - 40 Nm,
after protecting their thread with anti-seizing products.

tight: after the start-up, check there is no leakage
of flue gases into the external environment.
