8.4 Checks
8.4.1 Checking the flue
Check that the flue is undamaged and complete.
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 section "Expansion vessel").
Once the checks described above have been completed:
– refill the boiler as described in section "SYSTEM Filling"
– check that the siphon has been filled correctly
– Start the boiler, activate the "Chimney sweep function" and
carry out combustion analysis as detailed in Appendix 2
– refit the front panel securing it with the two screws which
were removed previously.
