How to fix Wolf CGB-50 when no flame is established?
If no flame is established during the burner start in your Wolf Boiler, first, check the gas supply pipe and open the gas shut-off valve if it's closed. Then, inspect the ignition electrode and cable. Finally, press the reset button.
Why does the ionization current fluctuate in my Wolf CGB-50?
If the ionization current fluctuates in your Wolf Boiler, it may be caused by a blocked siphon or flue gas system, or a severe storm. Clean the siphon, check the flue gas system and ventilation air, and check the monitoring electrode.
How to troubleshoot a faulty flow sensor or low gas pressure in Wolf CGB-50 Boiler?
If your Wolf Boiler indicates a faulty flow sensor or gas pressure is too low, check the lead and the flow sensor. Also, check the gas pressure and the gas pressure switch (accessory).
Why is the LED constantly red on my Wolf Boiler?
If the LED is constantly red on your Wolf Boiler, it indicates that the ionization lead is shorted out or the ionization electrode is earthed (housing). Check the ionization lead and the position of the electrode to the burner. Press the reset button.
What causes TBA excess temperature and positive pressure in Wolf CGB-50 Boiler?
If your Wolf Boiler displays a TBA excess temperature and positive pressure in the flue gas system, check for correct installation of the combustion chamber pot. Also, check the flue gas system and ventilation air system.
How to resolve DHW excess temperature in Wolf Boiler?
If your Wolf Boiler shows a DHW excess temperature, check the system pressure and vent the heating system. Set the pump to stage 2 or 3.
What causes a gas fan fault in a Wolf Boiler?
If the gas fan in your Wolf Boiler doesn't reach the required pre-purging speed, ignition speed or doesn't stop, check the gas fan supply cable and the gas fan itself. Then, press the reset button.
Why does my Wolf CGB-50 show TBV excess temperature and low water pressure?
If your Wolf Boiler displays a TBV excess temperature and the water pressure is too low, check the system pressure and heating circuit pump. Also, check the HC pump step switch and vent the heating system. Press the reset button. Clean the heat exchanger and check the TB combustion chamber. Finally, increase system pressure.
What to do if Wolf CGB-50 Boiler flame fails during operation?
If your Wolf Boiler experiences flame failure within 15 seconds after flame recognition, check the CO values and inspect the ionization electrode and cable. Then, press the reset button.
