Checks
8.4.1
Checking the smoke duct
It is recommended that the user checks that the combustion air
inlet duct and smoke outlet duct are integral and airtight.
8.4.2
Checking the expansion vessel pressure
It is recommended that the expansion vessel on the water side
is drained and that the prefilling pressure is not less than 1 bar .
If this is not the case, pressurize it to the correct value (see
sectionExpansion vessel".
Once the checks described above have been completed:
– refill the boiler as described in section "REFILL operations"
– start the boiler up and carry out a smoke analysis and/or
measure the combustion efficiency.
– refit the front panel securing it with the two screws which
were removed previously

Unscheduled maintenance
When a replacement is made:

– the nozzles for gas conversion
– the electronic board following a fault
– the gas valve following a fault.
Check that the parameter settings are correct.
To go into " Parameter setting and display ", please refer to the
instructions in the relevant section.
Once the parameters in the table have been set, you MUST carry
out the FULL GAS VALVE CALIBRATION described in the relevant
section.
