Before carrying out any cleaning and maintenance operations,
isolate the heater from the mains power supply from the switch
located on the electrical system and/or on the shut-out devices.
If the heater is faulty and/or incorrectly operating, switch it off

Technical Service.
All repairs must be carried out by using genuine spare parts.
Failure to comply with the above instructions could compromise
the safety of the equipment and invalidate the warranty.
If the equipment is not used for long periods, shut the gas
supply off through the gas stopcock and disconnect it from the
power supply.
If the heater is to be put out of service, in addition to the above
operations, potential sources of hazard on the unit must be
removed.
It is strictly forbidden to obstruct the Venturi pipe inlet, located
on the burner-fan unit, with your hands or with any other objects.
Any obstruction could cause a backfi re from the premixed
