do not operate electrical contacts or switches (doorbell,
lights, motor, lift, etc.).
1.Cut the gas supply
2.Open the windows
3.Extinguish all flames
4.Evacuate the premises
5.Contact a qualified professional
6.Inform the gas supplier
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
Avoid direct contact with the flame viewport.
Depending on the settings of the appliance:
- The temperature of the flue gas conduits may exceed 60°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 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 instalation.
Before any work, switch off the mains supply to the
appliance.
Check regularly that the installation contains water and is
pressurised.
Keep the appliance accessible at all times.
Avoid draining the installation.
The appliance should be on Summer or Antrifreeze mode rather than
switched off to guarantee the following functions:
- Antifreeze protection
- Protection against corrosion on domestic hot water tanks fitted
with a titanium anode

The panel must always be supplied with 230V voltage:
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.
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.
Make all other settings on the master boiler fitted with a DIEMATIC-
m3 control panel
Press the
- to ensure the anti-grip of the heating pump,
- to ensure Titan Active System® operation when a titanium anode
is protecting the DHW tank.

- "summer" to shut down the heating.
- "antifreeze" to shut down the boiler if you are to be absent.
Domestic hot water circuit:
Drain the domestic water tank and pipes.
Only for control panel DIEMATIC-m3:
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.

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. 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.
