Ignition electrode

- Check the positioning and conditions

The modular system becomes dirty 

very quickly

Combustion

- Check the combustion controls

The burner does not start upon con-

sent of the modular system control

Gas valve

- Check for the presence of 230Vac 

voltage on the gas valve terminals, 

check wiring and connections

The modular system does not start

No electric power supply (no mes-

sage on the display)

- Check the electric connections

- Check the condition of the fuse

The modular system does not arrive 

at temperature

Burner capacity insufficient

- Check and adjust the burner

Modular system adjustment

- Check correct functioning

- Check the temperature setting

The generator triggers a thermal 

safety block

No water

- Check correct functioning

- Check the temperature setting

- Check the electrical wiring

- Check the position of the sensor 

bulbs

Modular system adjustment

- Check the bleed valve

- Check the heating circuit pressure

The generator is at temperature but 

the heating system is cold

Presence of air in the system

- Bleed the system

Pump malfunctioning

- Check/unseize the pump

- Replace the circulator

- Check the electrical connection of 

the circulator

The circulator does not start

Pump malfunctioning

- Check/unseize the pump

- Replace the circulator

- Check the electrical connection of 

the circulator

Frequent tripping of the system 

safety valve

System safety valve

- Check calibration or efficiency

Frequent tripping of the system 

safety valve

Incorrect circuit pressure

- Check the circuit pressure

- Check pressure reducer functioning

Frequent tripping of the system
