TROUBLESHOOTING

Appliance malfunctions/faults are indicated on the display as shown in the table on page 49.

Fault

Cause

Remedy

Smell of gas

-  Gas supply circuit

- Check sealing efficiency of the joints 

and closure of the pressure points

Smell of uncombusted fuel

-  Flue circuit

- Check:

  - sealing of joints

  - for possible obstructions

  - combustion quality

Irregular combustion

- Supply gas pressure

-  Check settings

-  Burner and/or exchanger dirty

-  Check conditions

-  Intake and/or exhaust lines dirty 

-  Check conditions

-  Incorrect blower RPM

- Check the blower RPM (see page 

45).

Delayed ignition with pulsing on burner - More precise tuning of ignition power 

required

-  Modify settings

The generator does not reach the set 

temperature

-  Generator heat exchanger dirty

-  Clean the combustion chamber

-  Insufficient burner flow rate

-  Check burner settings

The generator reaches the set 

temperature but the heating systems 

are cool

-  Presence of air in the system

-  Purge the system

- System pump

-  Unblock the pump

-  Replace the pump

Frequent intervention of the system 

safety valve

-  System safety valve

-  Check setting or efficiency

-  System pressure

-  Check filling pressure

-  Check pressure reducer

-  Check filling valve

-  System expansion vessel

-  Check efficiency

System pump/s do not work

-  Pump blocked, electrical connections -  Check pump and connections

-  Room thermostat

-  Check room thermostat and 

connections

Storage tank pump does not work

-  Pump blocked, electrical connections

-  Check the pump

- Check the electrical connection 

between the pump and control panel

-  Storage tank thermostat

- Check efficiency and position of the 

thermostat 

However, other anomalies may occur on the appliance/system, and these are listed below.
