RECOMMENDATIONS FOR THE BOILER MAINTENANCE
Essential recommendations for the electrical safety
•
Before opening the boiler for maintenance, turn off the boiler by pushing on the
ON/OFF master switch.
•
Isolate the external power supply of the appliance before performing any
operation, unless it is required to take measurements or perform system setup.
Essential recommendations for safety
•
Water flowing out of the drain valve may be extremely hot and could cause severe
scalding.
•
Do not use solvents to clean any of the burner components. The components could
be damaged, resulting in unreliable or unsafe operation.
•
Check the tightness of the flue pipe connections.
Essential recommendations for the correct operation of the appliance
•
It is recommended to have the boiler and the burner serviced at least once a year
or every 1,500 hours
by a qualified technician, preferably at the start of the heating
season. More frequent servicing may be required depending on boiler use. Please
consult your installer for advice.
•
The boiler and burner maintenance will be carried out by a qualified engineer, and
the defective parts may only be replaced by genuine factory parts.
•
Make sure to replace any gaskets or seals on the removed components before
reinstalling them.
•
To ensure maximum efficiency and reliability of the unit, it is recommended that
the end-user perform the periodic checks mentioned in the Safety section of this
manual.
•
Control the tightness of the hydraulic circuit connections.
