Risk of damage
Do not stock chloride or fluoride compounds close to the
appliance.
Install the appliance in frost-free premises.
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
Only qualified professionals are authorised to work on the
appliance and the installation.
Before any work, switch off the mains supply to the

m3 control panel
Press the *key.
4.3 Switching off the boiler
- Set the On/Off switch to 0.
- Close the gas valve
DIEMATIC-m3 control panel
The 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 anode
is 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 water
freezing. If this cannot be done, drain the system completely. In all
cases, consult the fitter.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
4.4 Commissioning the boiler
Initial commissioning must be done by a qualified
professional.
1. Check the water pressure in the installation. Top up with more
water 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
9
- 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:
- Turn the AUTO /
!
/ TEST STB switch to AUTO .
- Turn the pump shutdown switch to
9
- Set the boiler thermostat to maximum (between 7½ and 9).
`K3 control panel (Secondary boiler in cascade with a
DIEMATIC-m3 boiler):
-Setswitch AUTO /
!
/ TEST STB to the AUTO position.
4. Turn the burner switch to 2(2 stage version)
5. Check that the safety thermostat has not triggered. Remove the
safety thermostat hood and press the reset button with a
screwdriver.
6. Set the On/Off switch to 1.
Only for DIEMATIC-m3 control panel:
When the boiler is switched on, the tank exchanger is purged
for one minute if a tank is connected and its temperature is
lower than 25°C.
If disgassing has already taken place, press the MODE key to
suspend disgassing.
Only for DIEMATIC-m3 control panel:
On commissioning, it is necessary to select the desired
language with the + and - keys and confirm with the MODE key.

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 more
heating 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 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.

7. Technical specifications
Warranty
You 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.
France
The preceding dispositions are not exclusive of benefits for the
purchaser of the legal guarantee as stated in Civil Code articles
1641 to 1648.
Poland
Warranty conditions are included in the warranty card.
Switzerland
The application of the warranty is subject to the terms and
conditions of sale, delivery and warranty of the company marketing
our products.
Belgium
The preceding dispositions about the contractual guarantee are not
exclusive of profit if the need arises for the purchaser in Belgium of
the applicable legal dispositions on hidden defects.
Italy
The duration of our warranty is shown on the certificate delivered
with the appliance.
Our liability as manufacturer may not be invoked in respect of
incorrect use of the appliance, incorrect or insufficient maintenance
thereof, or incorrect installation of the appliance (you must
therefore ensure that installation and maintenance operations are
carried out respectively by a qualified professional and by an after
sales service company).
The legislation laid down by European Directive 99/44/EEC,
transposed by Legislative Decree No. 24 of 2 February 2002
published in O.J. No. 57 of 8 March 2002, continues to apply.

consumer, which are guaranteed by the legislation of the Russian
Federation as regards hidden defects.
The terms and conditions of warranty and the terms and conditions
of application of the warranty are indicated on the warranty form.
The warranty shall not apply as regards the replacement or repair
of wearing parts under normal use. Such parts include
thermocouples, injection nozzles, flame control and ignition
systems, fuses and gaskets.
Turkey
Due to the laws and regulations the product life for this product is
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.
