Ignition Failure
No gas supply to the
boiler.
1-
Ensure that the gas valve is on.
2- Ensure that there is gas supply.
3- If the gas valve is off, turn it on and press the reset button.
4- Check the gas setting. If there is a problem, adjust the gas setting according to the table given in
the manual and reset the device.
5- Check fan-venturi-silencer assemblies.
6- Check if the siphon is clogged. Ensure that the connection is slopping at least 3° downwards and
there is water in the main heat exchanger up to the part where the electrode is located.
7- If the siphon is clogged, clean it. If there is a problem with the gland, replace it. If the electrode is
wet, replace it. Then reset the device.
8- Ensure that the connection of the electrode cable (both on the mainboard and on the main heat
exchanger) is done correctly and that it sits properly. If there is a problem, make sure it is properly
installed and locked. Then reset the device.
9- Check the cable connections and ensure the cables are not damaged. If there is damage, replace
them and reset the device.
10- If the problem persists, remove the ignition electrode and check for oxidation. If there is oxidation,
clean the electrode and place it back and then reset the device.
11- Check the distance of the ignition and ionization electrodes. If there is a problem, adjust it
according to the measurements given in the manual. Then reset the device.
12- Turn off the boiler and check for a resistance of 110-120 ohm between the ends of the gas valve.
If the resistance value is not within this range, replace the gas valve.
13- Remove the gas valve connector and turn on the boiler's electrical connection. Ensure that there
is a voltage of 23-25 V between the ends of the connector from the mainboard during ignition. If it is
not in this range, replace the mainboard.
