The boilers are managed by a circuit board with microprocessor with a lambda probe that corrects boiler
functioning anomalies by means of constant analysis of the exhaust gases.
The data obtained from the combustion tests have been realised using the following fuels:
ONORM M7 135 DIN PLUS Pellets.
* Realise a suitable anti-condensate circuit in a way to guarantee a minimum water temperature returning
to the boiler that is equal tot he value indicated (see “SAFETY DEVICES” chapter”).
