gas
- Purge the gas supply pipe then reset the heater using the panel reset
button
- Faulty gas valve (1st stage) - Check the gas valve and replace if necessary.

- Commissioning by switching off
the draught diverter thermostat
- Check for adequate draw on the chimney connection. Press the reset
button on the safety control box.
- No ionisation current
- Check the ionisation probe and earth wire connection.
- Check the position of the ionisation probe and the flame diffuser in the
ignition burner

Please note the seriousness of unplanned intervention on the
combustion product evacuation checking device : evacuation faults must
be solved by improving the draught in the chimney.
In the event of a thermostat fault, it must be replaced by a part stated on
our "Spare parts list". It position must not be changed, it is defined by the
2 fixing brushes which are positioned in 2 holes in the anti-blowback
