4 Operating the appliance

4.1 Commissioning the boiler

Initial commissioning must be done by a qualifiedprofessional.

1. Check the water pressure in the installation. Top up with morewater if necessary.

2. Open the gas valve.

3. Make the settings on the control panel:

B3 control panel:

- Turn the switch TEST-STB/ / to .- Turn the pump shutdown switch to - Set the boiler thermostat to the desired setting.- When preparing domestic hot water: Set the DHW thermostat to

the desired setting. Setting 6 (approx 60) recommended.

DIEMATIC-m3 control panel:

4.3 Switching off the boiler

Set the On/Off switch to 0.

DIEMATIC-m3 control panelThe panel must always be supplied with 230V voltage:

- to ensure the anti-grip of the heating pump,

- to ensure Titan Active System® operation when a titanium anodeis protecting the DHW tank.

Use the mode:- summer to shut down the heating.- antifreeze to shut down the boiler if you are to be absent.

4.3.1 Precautions to take if there is a danger of frost

Heating circuit:Use a correctly dosed antifreeze to prevent the heating waterfreezing. If this cannot be done, drain the system completely. In allcases, consult the fitter.

Domestic hot water circuit:Drain the domestic water tank and pipes.

4.3.2 Precautions to take in the event of prolonged shutdown (one year or more)

- Close the gas valve- The boiler and the chimney must be swept carefully.

- Close the door of the boiler to prevent the internal circulation of air.

5 Checking and maintenance

Make the following checks at least 1 time a year:- Checking the ignition burner- Safety devices- Water level- Checking burner safety- Checking the safety thermostat- Checking the downdraught thermostat

Carry out the following maintenance at least 1 time a year:- Cleaning main burner and ignition burner- Cleaning of the heating body- Cleaning painted surfaces

6.3 Incidents and solutions

The burner is not working:- Check the boiler thermostat settings.- Shutdown by the safety thermostat due to accidental overheating

Check that the safety thermostat has not triggered. To restart theboiler, reset the safety thermostat. Remove the safety thermostathood and press the reset button with a screwdriver. Carry out thestart-up operations again. Call your fitter.

- Check the circuit breaker

- The safety control box is malfunctioning (Fault indicator lightilluminated)

Press the resetting button of the burner. Call your fitter.

The burner is operating but the radiators are cold:- Bleed the radiators.- Top up the primary circuit with water.

If it is often necessary to top up the installation with water, contactyour fitter.

- Check that the heating pump is operating correctly.- Check the position of the 3 position switch.

8 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 moreheating it consumes.

- Turn heating off when airing a room (5 minutes a day is sufficient)Avoid deregulating the thermostat. Switch the On/Off switch to Off.

- Do not shut down heating completely if you are absent. Lower thethermostat by 3-4°C.

- Use the sun's heat as much as possible.- Take showers rather than baths. Use a water-saving shower head.

WarrantyYou have just purchased one of our appliances and we thank you

for the trust you have placed in our products. Please note that your

appliance will provide good service for a longer period of time if it is

regularly checked and maintained. Your fitter and our customer

support network are at your disposal at all times.

Warranty terms

Starting from the purchase date shown on the original fitter's

invoice, your appliance has a contractual guarantee against any

manufacturing defect.

The length of the guarantee is mentioned in the price catalogue.

The manufacturer is not liable for any improper use of the appliance

or failure to maintain or install the unit correctly (the user shall take

care to ensure that the system is installed by a qualified fitter). In

particular, the manufacturer shall not be held responsible for any

damage, loss or injury caused by installations which do not comply

with the following:

- applicable local laws and regulations

- specific requirements relating to the installation, such as national

and/or local regulations

- the manufacturer's instructions, in particular those relating to the

regular maintenance of the unit

- the rules of the profession

The warranty is limited to the exchange or repair of such parts as

have been recognised to be faulty by our technical department and

does not cover labour, travel and carriage costs. The warranty shall

not apply to the replacement or repair of parts damaged by normal

wear and tear, negligence, repairs by unqualified parties, faulty or

insufficient monitoring and maintenance, faulty power supply or the

use of unsuitable fuel. Sub-assemblies such as motors, pumps,

electric valves etc. are guaranteed only if they have never been

dismantled.

purchaser of the legal guarantee as stated in Civil Code articles

the applicable legal dispositions on hidden defects.

consumer, which are guaranteed by the legislation of the Russian

Federation as regards hidden defects.

of wearing parts under normal use. Such parts include

thermocouples, injection nozzles, flame control and ignition

systems, fuses and gaskets.

10 years. During that time the producer and/or the distributor has

to provide after sales services and spare parts.

Other countries

The above provisions do not restrict the benefit of the legal laws

regarding hidden defects applicable in the buyer's country.
