2 Safety instructions and recommendations
2.1 Safety instructions
For a proper operating of the boiler, follow carefully the
instructions.
Only qualified professionals are authorised to work on the
appliance and the instalation.
Incorrect use or unauthorised modifications to the
installation or the equipment itself invalidate any right to
claim.
The condensates in oil-fired condensing boilers are acidic
(2 < pH < 3): The installation of a condensates
neutralisation system is recommended.
Before any work, switch off the mains supply to the
appliance.
Keep to the polarity shown on the terminals: phase (L),
neutral (N) and earth
Keep children away from the boiler.
Fire hazard
It is forbidden to store inflammable products and materials
in the boiler room or close to the boiler, even temporarily.

.
Risk of intoxication
Do not obstruct the air inlets in the room (even partially).
If you smell flue gases
1.Switch the appliance off
2.Open the windows
3.Evacuate the premises
4.Contact a qualified professional
Risk of being burnt
Depending on the settings of the appliance:
- The temperature of the flue gas conduits may exceed 65°C
- The temperature of the radiators may reach 95°C
- The temperature of the domestic hot water may reach 65°C
Risk of damage
Do not stock chloride or fluoride compounds close to the
appliance.
.Install the appliance in premises sheltered from rain, snow
and frost.
Do not neglect to service the appliance: Contact a qualified
professional or take out a maintenance contract for the
annual servicing of the appliance.
2.2 Recommendations
• Check regularly that the installation contains water and is
pressurised.
• Keep the appliance accessible at all times.
• Avoid draining the installation.
• Use only original spare parts.
• Never remove or cover labels and rating plates affixed to the
appliance.
• Boiler with DIEMATIC-m3 control panel: The appliance should
be on Summer or Antrifreeze mode rather than switched off to
guarantee the following functions:
- Cleaning the pumps
- Antifreeze protection
- Protection against corrosion on domestic hot water tanks fitted
with a titanium anode

6.2.1 Precautions required in the case of long boiler stops (one or more years)
• The boiler and the chimney must be swept carefully.
• Close all the doors of the boiler to prevent air from circulating inside the boiler.
• We advise removing the pipe which connects the boiler to the chimney and to close off the nozzle with a cover.
6.2.2 Precautions required if the heating is stopped when there is a risk of freezing
We recommend the use of a correctly dosed antifreeze agent to prevent to the heating circuit from freezing.
If this cannot be done, drain the system completely.

7.2 Hydraulic pressure
Checking the hydraulic pressure. The hydraulic pressure must be a
minimum of 0.8 bars. Adjust the pressure if necessary, avoiding a
sudden influx of cold water into the boiler when it is hot.
This operation should be required only a few times in each heating
season, with very low quantities of water; otherwise, look for the leak
and repair it.
7.3 Draining
We advise you against draining the system unless it is absolutely
necessary.
Carry out the following maintenance at least 1 time a year:
- Cleaning the burner
- Cleaning of the heating body
- Cleaning of the condenser
- Cleaning the siphon
- Cleaning the flue gas circuit
7.4 Maintenance
The boiler will only operate efficiently if the exchange
surfaces are kept clean.
Have the required checks and services done.
` The boiler must be serviced and fully cleaned and the flue gas
conduit swept by a qualified professional at least 1 times per
year.
` The condenser and the condensates neutralisation station must
serviced at least once a year by a qualified professional.
The siphon and the condensates evacuation conduit must
imperatively be checked and cleaned at least once a year.

8.3 Incidents and solutions
The burner is not working:
` Check the boiler thermostat settings.
` Carry out the checks mentioned in the burner instructions.
` Shutdown by the safety thermostat due to accidental
overheating:
• Boiler: Check that the safety thermostat has not triggered. To
restart the boiler, reset the safety thermostat. Remove the safety
thermostat hood and press the reset button with a screwdriver.
• Condenser: Check that the safety thermostat has not triggered:
- Unscrew the protection cap
- Press the resetting button of the burner
The burner is operating but the radiators are cold:
` Bleed the radiators.
` Checking the hydraulic pressure. The hydraulic pressure must
be a minimum of 0.8 bars. Adjust the pressure if necessary,
avoiding a sudden influx of cold water into the boiler when it is
hot.
If it is often necessary to top up the installation with water,
contact your fitter.
` Check that the heating pumps are working correctly
` Check the position of the 3 position switch.

10. Energy savings
10 Energy savings
Here are a few tips for saving energy:
- Install reflector panels behind the radiators.
- Do not cover the radiators. Do not hang curtains in front of the
radiators.
- Insulate pipes to prevent thermal losses and condensation.
- Do not obstruct aeration grates (even partially). They help to
reduce humidity in the home. The more humid a home, the more
heating it consumes.
- Turn heating off when airing a room (5 minutes a day is sufficient)
Avoid deregulating the thermostat. Place the start/stop switch on
Off.
- Do not shut down heating completely if you are absent. Lower the
thermostat by 3-4°C.
- Use the sun's heat as much as possible.
- Take showers rather than baths. Use a water-saving shower head.
