8.3 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.
