Failure to observe the above will render the warranty null and void. The names of the Authorised Service Centres are
indicated in the attached sheet. Prior to commissioning, remove the protective plastic coating from the boiler. Do not use
any tools or abrasive detergents to do this as you may damage the painted surfaces.
Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of danger.

Only an Authorised Technical Assistance Service can convert boiler operation from NATURAL GAS to LPG or vice-versa. To
perform calibration, set parameter P02 as described in the PARAMETER SETTINGS section. Lastly, check the combustion
parameters as described in the SPECIAL FUNCTIONS - CHECKING COMBUSTION PARAMETERS section.
When the gas change is completed the boiler data plate must be amended to indicate the new gas data.

19. ANNUAL SERVICING
If the boiler was operating, wait for the combustion chamber and pipes to cool down.
Before commencing any maintenance operations, make sure the boiler is disconnected from the power supply. After servicing,
reset the original operating parameters of the boiler if they were changed.

It is advisable not to use the service cap at the base to empty and clean the siphon. Remove the siphon from inside the boiler
and clean it with a jet of water. Fill the siphon with clean water and put back in place, making sure that it is properly connected.
