WARNINGS

Gas Leak or Fault

Turn off the gas emergency control valve immediately. Eliminate all sources of ignition, i.e. smoking, blowlamps, hot air

guns, etc. Do not operate electrical lights or switches either on or off. Open all doors and windows, ventilate the area.

Sheet Metal Parts

This boiler contains metal parts (components) and care should be taken when handling and cleaning, with particular

regard to edges.

Sealed Components

Under no circumstances must the User interfere with or adjust sealed parts.

Gas Category

This boiler is for use only on G20 natural gas, but the 30cxi may be
converted for use on G31 gas (Propane L.P.G.).

Gas Safety (Installation and Use) Regulations

In your own interests and that of safety, it is the Law that ALL gas
appliances are installed by a competent person in accordance with
the current issue of the above regulations.

Testing and Certifi cation

This boiler is tested and certifi cated for safety and performance.
It is, therefore, important that no alteration is made to the boiler,
without permission, in writing, by Saunier Duval.

Any alteration not approved by Saunier Duval, could invalidate the
certifi cation, boiler warranty and may also infringe the current issue
of the statutory requirements.

CE Mark

This boiler meets the requirements of Statutory Instrument, No.
3083 The Boiler (Effi ciency) Regulations, and therefore is deemed
to meet the requirements of Directive 92/42/EEC on the effi ciency
requirements for new hot water boilers fi red with liquid or gaseous
fuels.

Type test for purposes of Regulation 5 certifi ed by: Notifi ed body

0087.
Product/production certifi ed by: Notifi ed body 0086.
The CE mark on this appliance shows compliance with:

1. Directive 90/396/EEC on the approximation of the laws of the
Member States relating to appliances burning gaseous fuels.

2. Directive 73/23/EEC on the harmonisation of the Laws of the
Member States relating to electrical equipment designed for use
within certain voltage limits.

3. Directive 89/336/EEC on the approximation of the Laws of the
Member States relating to electromagnetic compatibility.

Control of Substances Hazardous to Health

Under Section 6 of The Health and Safety at Work Act 1974, we are
required to provide information on substances hazardous to health.

The adhesives and sealants used in this appliance are cured and
give no known hazard in this state.

Insulation Pads / Ceramic Fibre

These can cause irritation to skin, eyes and the respiratory tract.
If you have a history of skin complaint you may be susceptible to

irritation. High dust levels are usual only if the material is broken.
Normal handling should not cause discomfort, but follow normal

good hygiene and wash your hands before eating, drinking or going
to the lavatory.

If you do suffer irritation to the eyes or severe irritation to the skin
seek medical attention.

Electrical Supply

The boiler must be earthed.
All system components shall be of an approved type and all wiring

to current I.E.E. wiring regulations.
External wiring must be correctly earthed, polarised and in accor-

dance with the relevant standards.
In GB this is BS 6891.
In IE this is the current edition of I.S.813 “Domestic Gas Installa-

tions”.
The boiler must be connected to a permanent 230V ac, 50Hz sup-

ply.
Connection of the whole electrical system of the boiler, including

any heating controls, to the electrical supply must be through one
common isolator and must be fused 3 Amp maximum.

Isolation should be by a double pole switched fused spur box, with
a minimum gap of 3mm for both poles. The fused spur box should
be readily accessible and preferably adjacent to the appliance. It
should be identifi ed as to its use.

Alternatively connection can be made through an unswitched shut­tered socket and 3A fused 3-pin plug both to the current issue of BS

GREEN LED [1]

The green led can be off, fl ashing (slowly or rapidly) or on.

OFF: the boiler is electrically disconnected. In these conditions the boiler obviously

doesn’t work. The Automatic Anti Freezing and Anti Blocking functions can’t be acti­vated (prevents damage to boiler during long period of inactivity). The external general
switch could be off.

FLASHING (slowly): the boiler has power but the SUMMER/WINTER Selector is in central

position (0). The boiler will not provide heating or hot water but the boiler protection
systems are operating (Anti Freezing and Anti Blocking functions may ignite the boiler
and as such require the gas supply to be open).

FLASHING (rapidly): the Chimneysweep Function (which is reserved for the installer)

is on by mistake.

Turn it off bringing the SUMMER/WINTER selector on the central position (0) until

the green led fl ashes slowly.

ON: the boiler is on and the SUMMER/WINTER selector is in the SUMMER

the WINTER

Position. The boiler will provide heating and hot water on demand.

RED LED [7] - FAULT CODES AND LOCKOUTS

The red led [7] can be off, fl ashing or on.

Led OFF: the boiler is functioninging correctly.
Led FLASHING: signals a boiler fault. The display [5] will show a fault code:

Fault code “06” - the heating system temperature sensor (inside the boiler) is

damaged. Call a Qualifi ed Technician to repair.

Led ON - The display [5] shows a fl ashing code. Things to try:

Code “01” - If the boiler has just been installed, or adjustments have been made

to the gas pipes.

If the air-gas mix ratio is incorrect then this will prevent combustion and can

force the boiler into a state of lockout. In order to correct the mix you should
repeat the ignition process several times with the SUMMER/WINTER Selec-

tor on the 0 /

reset position until the red led turns off.

Code “01” - Ignition problems if no work has been carried out.

Ensure that the SUMMER/WINTER selector is on the 0 / reset position until the

red led turns off. If this does not happen or the boiler goes back into lockout please
ask your installer to check the following points:

• Check the CO

levels of the boiler are correct. Please refer to Technical Data

table in the section reserved for installers (in this manual);

• Check the fl ue outlet for leaks and inspect general condition clearliness.
Please refer to “Flue connection” in the section reserved for installers (in
this manual).

Instructions for Use

Technical Note for the TECHNICIAN: if the Flame Control Unit is not detecting a fl ame

it could be due to one of the following reasons:

• the fl ame has not ignited;

• the fl ame control unit has become disconnected from the burner.

If the boiler locks out again please call the group service for assistance.

Code “21” - You have insuffi cient water pressure (0.5 bar or lower).

Repressurise the system to the optimum pressure of between 1-1,5 bar

(cold) by following the procedure outlined in the paragraph “Commissioning”
in the section reserved for installers (in this manual).

If a system continues to lose pressure it would suggest a system leak and

the system should be inspected for water loss. Also check that all radiators

9 Frost protection

9.1 Boiler frost protection

In case of frost risk, do as follows:

•

Make sure the boiler is supplied with
electrical power and gas.

•

Turn the selector [2] on the 0 /
position (the green indicator
blinks).

The frost protection system operates the
boiler as soon as the temperature in the
heating circuit is under 5°C. The boiler
stops as soon as the water temperature in
the heating circuit reaches 30°C.

9.2 Frost protection activation

If you leave home for a few days, select

•
the minimum heating temperature on
the control panel of the boiler and just
decrease the setpoint temperature on
your room thermostat.
