SERVICING / MAINTENANCE

To ensure the continued efficient and safe operation
of the water-heater, it is recommended that it is
checked and serviced annually.
The technical maintenance of the appliance must
be carried out by a Saunier Duval approved
specialist who will more particularly inspect the
heating element, burner, safety mechanisms and
servo-systems.
If the appliance is installed in a region where water
is very hard and a drop in the water flow rate is noted
and/or a noise phenomenon, descaling of the heat
exchanger is required.

DRAINING

If there is a risk of frost it is essential to drain the
heater :
Shut off gas supply
Shut off water supply
open all hot water taps

CHANGING GAS TYPE

If the kind of gas supplying the appliance is
changed, certain parts of the burner and pilot need
to be modified.
These modifications and the new adjustments they
involve must only be carried out by a qualified
engineer.

To carry out this descaling :
Shut off water supply,
Open one or various hot water taps to drain the
water-heater,
Dismantle heat exchanger and fill with a 15 %
inhibited acid solution,
leave to act for 10 to 15 minutes then rinse
thoroughly,
If necessary, repeat operation.
The periodic cleaning of the panels of the water-
heater can be carried out with a cloth dampened
in soapy water. Do not use abrasive or solvent-based
chemicals, as they may damage the coating.
