11. Servicing instructions
To maintain efficient and safe operation of your boiler have it checked by
a Qualified Service Engineer at the end of every operating period.
Careful servicing will ensure economical operation of the system.
Do not clean the outer casing of the appliance with abrasive, aggressive
and/or easily flammable cleaners (i.e.: gasoline, alcohol, and so on). Always
isolate the electrical supply to the appliance before cleaning it (see section
