What to do if my Schwank infraSchwank D 15U burner does not start?
- J
  James TaylorAug 12, 2025
  If the burner on your Schwank Heater doesn't start, there could be several reasons: * There might be no gas supply. In this case, check the pre- and nozzle pressure. * There may be a fault in the electrical supply. * The thermostat might be set to "OFF". Ensure the thermostat is set to "ON". * The connection of the ignition- and ionization electrode could be wrong; ensure that it is correctly connected. * The differential pressure switch may be defective or out of order. Replace or repair the differential pressure switch.

  If your Schwank Heater control goes into a fault position during operation, it could be due to: * The flame being off, so ensure the flame is on. * The contact of the differential pressure switch opens, so check the differential pressure switch. * A poor flame signal, so improve the flame signal.

Why does my Schwank Heater control go into fault position during the safety time?

  Michelle GarciaAug 27, 2025
  If the control of your Schwank Heater goes into the fault position during the safety time, it could be due to: * No flame (no ignition, valve doesn't open, no gas). Check the ignition, valve operation, and gas flow. * No or poor flame signal (flame does not stick, bad insulation of the flame detector, no contact between burner and earth connection). Resolve the flame signal issue. * Wrong polarity, so check the polarity.

  If your Schwank Heater control goes into a fault position during the pre-purge period, this could be due to: * A flame signal wrongfully caused by an electrical defect of control, so address the electrical defect of control. * Insufficient pressure differential, so resolve the pressure differential issue.
