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

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.

3.4 FAULTS

The heater is equipped with an advanced self-diagnostic
system. If a problem arises with the unit, the fault symbol
will flash on the screen and the respective code will be
displayed.
Some faults, identified with the letter "A," will block unit
operation.
To restore operation, simply press the RESET key (4 -
fig. 1) for 1 second. If the heater does not reset, the fault
must be resolved.
Faults identified by the letter "F" cause temporary blocks
that are automatically resolved when the value returns to
the heater's normal operating range.
