boiler performs a lock-out and switches back on. To do this:
– modify the calibration of the heating thermostat
– adjust the room thermostat or the time programmer
– check that the system pump is working
– check that the boiler locks out completely by shifting the sys-
tem’s main switch and the device’s main switch to “off”.
If all the conditions are fulfilled, restart the boiler, bring it to full
power and analyse the combustion by-products.

Checking the combustion parameters
After running the boiler at full power, to conduct the combustion
checks it is necessary to connect a fume analyser and a fume
thermometer to the withdrawal socket (1), as illustrated in the
figure.

– CO (ppm) (as per the regulations in force)
– Bacharach index (≤ 0,5)
– the fume temperature
Check that the measured values are very close or equal to the val-
ues of the technical data table. If not, correct the regulations made.
