Before carrying out any operation inside the boiler, disconnect the electrical power and isolate
the gas supply.
Cleaning the boiler and burner
The body and burner must not be cleaned with chemical products or wire brushes. Special care must be
taken over all the seals pertaining to the sealed chamber (gaskets, cable clamps, etc.).
After performing all these operations, check and carry out all the phases of ignition and thermostat
operation, the gas valve and circulation pump.
After these checks, make sure there are no gas leaks.
Combustion analyser testing
It is possible to analyse the combustion through the
air and flue sampling points shown in fig. 15.
To make the measurement, it is necessary to:
1)
Insert the probes as far as the stop;
2)
Open a hot water tap;
3)
Adjust the hot water temperature to maxi-
mum.
4)
Wait 10-15 minutes for the boiler to stabilize*
5)
Take the measurement.
Analyses made with an unstabilized boiler
can cause measurement errors.
