require unplugging the unit,
and after any operations on the
unit's safety devices or compo-
nents.
3.2.1 Before igniting the water heater
• Carefully verify the tightness of the gas installation
using a soap and water solution to check for leaks in
the connections.
• Fill the hydraulic system and make sure no air is
present in the unit or system.
• Check that there are no water leaks in the system or
unit.
• Make sure the grounding and the connection to the
electrical installation are suitable.
• Check that the gas pressure is correct.
• Make sure there are no flammable liquids or materials
near the heater.
• To avoid damaging the connections, do not place the
heater on the floor with the connections facing down.
3.2.2 Checks during operation
• Turn on the unit.
• Make sure the fuel and water systems are tight.
• Check the efficiency of the air and flue gas ducts while
the heater is operating.

3.3 MAINTENANCE
3.3.1 Periodic checks
In order for the unit to operate correctly, an authorized
technician must perform an annual inspection, checking
that:
• The control and safety devices (gas valve, flow switch,
etc.) operate correctly.
• The exhaust vent is perfectly efficient.
• The air and flue gas ducts and terminal are free of ob-
stacles and leaks.
• The burner and exchanger are free of dirt and deposits.
Do not use chemicals or steel brushes to clean them.
• The electrode is free of deposits and properly positio-
ned.
• The gas and water systems are perfectly tight.
• The gas delivery and operating pressure values are as
indicated on the tables.
A soft, damp cloth may be used to clean the
casing and exterior parts of the heater, using
soapy water if necessary. Do not use abrasive
detergents or solvents.
