GAS DELIVERY
As far as the gas delivery is concerned, considering that in general it is not possible to carry out a direct check up (meter)
it is possible to proceed empirically using the values of the boiler fume temperature.

MAINTENANCE
Skilled staff has to perform yearly the following operations:
- Check the valve inside tightness.
- Filter cleaning.
- Fan and head cleaning.
- Check the position of the ignition electrode tips as well as the control electrode.
- Calibrate the air and gas pressure switches.
- Check the combustion by means of CO
- Check all the gaskets and seal tightness.
Most components are visible: they can be identified and accessed immediately. Disassemble the upper plate to access
the inside of the head.
