- On safety because of a lack of
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.
- No spark from the electrode
- Check the electric cable connection to the safety box and the electrode
- 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
- Blocked filter or ignition burner

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
