How to Fix / Troubleshooting

Safety: Vibration can loosen connections and cause leaks. Shut down the boiler if vibration is severe.

Inspect burner mounting: Check that all bolts securing the burner to the Danstoker boiler front plate are tight.
Check fan impeller: Inspect the combustion air fan impeller for dirt buildup or damage. Clean and balance as needed.
Review combustion settings: Have a technician verify burner setup and adjust air/fuel ratio to eliminate pulsation.
Gas supply stability: If gas pressure fluctuates, consult the gas supplier or install a stabilizing regulator as per design.

Persistent vibration should be investigated by a burner specialist to prevent structural damage.

Excessive vibration or rumbling from the Danstoker burner or boiler casing during operation.
