5. Recommended annual checks (all boilers)
The safety valve should be checked annually, preferably before the heating season to ensure correct operation
and avoid accumulation of lime scale. It is not recommended to annually drain the system to protect the system
from freezing as refilling with fresh water will increase the risk of limescale attack
We recommend inspection of the boiler once a year by an authorized service engineer. This service is not
included in the guarantee. During the inspection all electric and water connections should be tightened, the
system should be vented and – if necessary – filled up, valves and general functionality of the device and safety
valves should be checked.
When cleaning the product do not use an aggressive liquid as e.g. gasoline, kerosene or solvent. For the external
shell and decorative cover, liquid for cleaning plastics or dish washing media may be used. Control panel should
be cleaned with dry or moist cloth (not wet).
