Q - Cleaning
The only cleaning operations that we recommend are those involving
the external boiler panels, which should be cleaned using just a cloth
dampened with soap and water.
In the case of stubborn marks, dip the cloth in a mixture of 50% water
and methylated spirits, or use specific products.
Do not use fuels and/or sponges soaked in abrasive solutions
or powder detergents.
It is forbidden to carry out any cleaning operations before dis-
connecting the boiler from the mains electricity supply; to do
this, turn the main system switch to “off”.
