How to fix flue gas/supply air damper that does not respond on Wolf Boiler?
If the Wolf Boiler's flue gas/ventilation air damper contact (E1) fails to close or open when there is a demand, you should check the flue gas/ventilation air damper and its wiring.
What to do if Wolf COB Boiler has flame failure during operation?
If the Wolf Boiler experiences flame failure during operation, it may be due to excessive negative pressure on the oil pump, flue gas return in the supply air, or a contaminated boiler. To address this, check CO values, inspect the flame monitor and lead, press reset, check the fuel system for leaks, or seek professional service.
What to do if the Wolf Boiler has no flame established?
If your Wolf Boiler isn't establishing a flame, several factors could be at play. Start by checking the oil line and fuel level. Inspect the ignition electrode and ignition transformer, and then press the reset button. Also, check the inspection window for the flame monitor or mixer head. Other potential issues include a faulty flame monitor and lead, siphon backpressure, or blocked condensate drainage. Maintenance might be necessary.
What to do if Wolf COB Boiler displays temperature limiter - excess temperature?
If the flow in your Wolf Boiler exceeds the temperature limiter's limit of 100 °C, triggering the temperature limiter excess temperature error, you should vent the system and check the heating circuit pump.
What to do if Wolf COB shows flue gas sensor, excess temperature?
If the flue gas temperature on your Wolf Boiler has exceeded 120 °C, triggering the flue gas sensor, excess temperature error, you should clean the heat exchanger. Also, verify that all displacement devices are installed, check the flow through the boiler, ensure the flow and return are properly connected, and then press the reset button.
How to fix HLSC excess temp on Wolf Boiler?
If the Wolf Boiler's flow temperature exceeds 110 °C, it triggers the HLSC excess temperature error. To resolve this, you should test the heating circuit pump, vent the system, press the reset button, and clean the heat exchanger.
What to do if Wolf COB shows flame pretence?
If your Wolf Boiler indicates flame pretence, meaning a flame is recognized before the burner starts, press the reset button. Also, check the solenoid valve for the oil pump.
What to do if the flue gas/ventilation air damper does not move in Wolf Boiler?
If the flue gas/ventilation air damper in your Wolf Boiler isn't moving, start by checking the flue gas/ventilation air damper and its wiring. The issue may be that the damper contact (E1) fails to close or open when there is a demand.
What to do if my Wolf COB fan does not stop?
If the fan in your Wolf Boiler isn't stopping, check the power cable to the fan and the fan itself. Then, press the reset button.
What to do if my Wolf Boiler shows TW excess temperature?
If your Wolf Boiler displays a TW excess temperature warning, it means the flow has exceeded the temperature limiter's limit of 100 °C. Vent the system and check the heating circuit pump.
