2 Safety instructions and recommendations
2.1 Safety instructions
Fire hazard
Do not stock products of an inflammable nature close to
the appliance.
If you smell gas, do not use a naked flame, do not smoke,
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:
- to ensure the anti-grip of the heating pump,
- to ensure Titan Active System® operation when a titanium anode
is protecting the DHW tank.
Furthermore, if an interactive remote control (CDI 2) is connected
and the 1switch is in the off 7position, there will be no display on
the CDI 2.
