2. Important recommendations
2.2 Maintenance
- The servicing and cleaning of the boiler and the sweeping of the
flue gas pipe and the bleed pot must be done at least once a year
by a qualified professional.
- We recommend taking out a maintenance contract.
- Regularly check the level of water in the system and top up if
required, taking care that cold water is not added suddenly into the
boiler when it is hot. If this operation is repeated several times per
season, locate the leak and repair it.

Do not drain the installation, except in cases of absolute
necessity. For example: Several months' absence with the
risk of ice in the building.

„ Belgium:
The operations required to switch from one gas to another must be
carried out by a SERV'elite technician.
