The burner does not
ignite and the safety box
is not affected (red alarm
indicator off) - 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 - 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
- No ionisation current - Check the ionisation probe and earth wire connection.
