What to do if my Wolf MGK-130 Boiler's gas fan does not reach the required pre-purging speed?
If the gas fan does not reach the required pre-purging speed, check the gas fan supply cable and the gas fan; press the reset button.
What to do if the Wolf MGK-130 shows a faulty flow sensor or gas pressure is too low?
If the flow temperature sensor or lead is faulty, or the gas pressure is lower than the value set at the gas pressure switch (only displayed after 15 min), check the lead, the flow sensor, the gas pressure, and the gas pressure switch settings.
What to do if my Wolf MGK-130 Boiler has a flame pretence?
If a flame is recognized before the burner starts, press the reset button.
What to do if my Wolf Boiler shows TW excess temperature?
If the flow/return temperature has exceeded the limit for the TW shutdown temperature, check the system pressure, vent the system, and set the pump to stage 2 or 3.
Why is my Wolf MGK-130 Boiler's LED constantly red?
If the LED is constantly red, it might be because the ionization cable is shorted out or the ionization electrode is earthed (casing). Check the ionization cable and the position of the electrode to the burner. Press the reset button.
What to do if my Wolf MGK-130 Boiler shows TBA excess temperature and overpressure in the flue gas system?
If the flue gas temperature has exceeded the limit for the TBA shutdown temperature, the flue gas system is blocked, or the ventilation air is blocked, clean the heat exchanger, check the flue gas system, and check the ventilation air system.
What to do if my Wolf MGK-130 Boiler shows TBV excess temperature and water pressure is too low?
If the flow temperature has exceeded the limit for the TBV shutdown temperature, or the condensate lifting pump has a fault, or the water pressure switch switches off at a pressure less than 1.0 bar, check the system pressure, the heating circuit pump and vent the system. Press the reset button. Check the condensate pump and increase system pressure.
What to do if the Wolf MGK-130's flame fails during operation?
If the flame fails within 15 seconds after flame detection, check the CO values and the ionization electrode and its cable. Press the reset button.
