INTRODUCTION
These instructions describe how to install and
use Saunier Duval appliances. It is important to
pay attention to the warnings on the packaging
and the casing of the appliances, and follow the
information given in this document.
These water-heaters are gas-fired appliances pro-
viding instant hot water to fill a sink or a bath.
The OPALIA X13 water-heater is of the room-sealed
type, that is the venting of combustion products and
the incoming fresh air pass through a flue system.
This venting principle offers a variety of advantages,
such as :
- installation with greatly reduced space require-
ments and with no need for room ventilation;
- a number of installation configurations depending
on the constraints of the premises.
The OPALIA X13 water-heater is of the II2H3+ gas
category for use with either natural gas (G20),
butane (G30) or propane (G31)
The water-heater is delivered for a flue system
connection with a top outlet to right or left.
Its variable input means that whatever the rate at
which water is drawn, there will be instantaneous
hot water at a very nearly constant temperature
within the maximum capacity of the appliance.
The ignition system on this water-heater with no
permanent pilot has been designed to achieve
maximum energy saving.

WATER HEATER INSTALLATION
LOCATION
When determining the siting of the water heater,
make sure you keep an approx. distance of 50 mm
between the sides of the appliance to ensure total
accessibility for servicing.
The jig will enable you to determine the position of
the flue system hole at the top outlet. All informa-
tion regarding the installation of the flue system is
provided in the flue system package.
If the water-heater is not fitted straight away, the
water and gas fittings must be protected from
contaminents E.G. plaster, paint.

INSTALLATION
Before installing the water-heater, the water
pipework must be flusched out to ensure that there
is no foreign matter present that could damage the
heater.
NOTE : do not use solvent products.
●Using the template supplied, fasten the hanging
bracket onto the wall.
●Hang the water heater onto the hanging bracket.
● Connect the pipework and fittings, supplied, to
the gas inlet, cold water inlet and hot water outlet,
see diagrams.
ELECTRIC POWER SUPPLY
Warning : the power supply cable built into the
water-heater is specific to it. If you wish to replace
it, please order a new one quoting part number
59114 from an approved Saunier Duval dealer.
●Connect the water-heater power supply cable to
the 230V mains supply. Ensure that the live and
neutral are connected correctly. To comply with
current standards, this connector must be made
through a double-pole switch with a contact
separation of no less than 3 mm.

Operating principles
The OPALIA X13 water-heater operates with no per-
manent pilot :
-when a hot water tap is opened, the gas entering
the burner is ignited by a spark train emitted by the
ignition electrode. A second electrode checks for
thepresence ofa flameat theburner, theappliance
is shut down by disconnection;
-when the hot water tap is closed, the gas input is
cut off by the valve and the appliance is shut down.
IMPORTANT : before operating the boiler, remove
the two fan transit packing pieces
Safety shutdown
A malfunction or an abnormality gives rise to the
disconnection of the appliance, and the safety
indicator (4) lights ...............................................
To restart the water-heater,
press the RESET button (3) ..................................
SAFETY DEVICES
Air flow safety device (air pressure switch )
In the event of even
partial blockage of the
flue, for whatever reason
resulting in a reduced air
flow, the water-heater’s
built-in safety device
comes into operation :
the burner is shut down
whilst the fan continues to operate. The water-
heater is ready to operate as soon as the fault has
been rectified.
In the event of loss of gas supply
The safety device automatically disconnects the
water-heater. When the gas supply is restored, press
the "RESET" button .
In the event of a power cut
The water-heater will cease to operate. When the
electricity supply is restored, the heater will auto-
matically restart.
Overheat cutout device
If anything occurs
which results in the
overheat cutout
device shutting down
the water-heater,
please call your nearest
approved after-sales
organisation.
IMPORTANT : It is
forbidden to bypass or tamper with any of the safety
devices. If, after attempting to use the heater, a
safety shut-down condition occurs, this must be
rectified immediately by a qualified, competent
person.

SERVICING / MAINTENANCE
DRAINING
CHANGING GAS TYPE
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.
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
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.
Toensure thecontinued efficientand safeoperation
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.
