Cleaning the boiler
Use a cloth damped in soapy water to clean the boiler’s external
paneling.
To remove stubborn marks, use a cloth damped in a 50% mix of water
and denatured alcohol or a suitable cleaning product.
Carefully dry the boiler after cleaning.
Clean the boiler and remove any carbon deposits from the surfaces of
the heat exchanger
at least once a year
. This not only extends the
boiler’s working life, but also keeps it efficient in terms of heat output
and consumption.
▶ Open the door [1] and pull out the turbulators [2].
▶ Use a flue brush [3] or other suitable tool to clean inside the
combustion chamber and the flue gas pipes.

remove it from the boiler.
▶ Check at regular intervals that the condensate drain [2] is not
blocked.
