1 Installation - Water level - Draining
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.
This operation should be required only a few times in each heating
season, with very low quantities of water; otherwise, look for the leak
and repair it.
2 Boiler
The boiler will only operate efficiently if the exchange
surfaces are kept clean
The boiler must be cleaned as often as necessary and, like the
chimney, at least once a year or more in accordance with the
prevailing regulations and the insurance contract taken out.
