5. COMMISSIONING
5.1. Unlocking the boiler
!
WARNING:
During commissioning, the unlocking of the boiler can only be achieved
if the hydraulic system is compliant with the recommendations
mentioned in the hydraulic diagrams (see section 8.3, page 54). The
person in charge of this operation must ensure such compliance.
Unlocking the temperature:
Modify parameter 2212 from 70° C to the desired value (Maximum 85°C).
Unlocking the power:
Increase the value of parameter 9529 up to the value of parameter 9530
(corresponding with the nominal power of the boiler).
!
WARNING:
Adjusting the boiler to operate using propane results in the
modi
fi
cation of parameter 9529; the boiler power locking function is
therefore no longer active.

For a cascade installation, check the hydraulic balance of the boilers.
Check that pressure when cold is at least 1 bar.
If this is a boiler room renovation, ensure that
fl
ushing and if necessary
silt removal from the installation have been correctly done (see
paragraph 1.5, page 7 of these instructions).
Check the
fl
ue-gas connections depending on the type of chimney (refer to
paragraph 4.9, page 24).
Check that the gas pressure and type are suitable for the products.
