Oil smell and visible oil around the burner or on the floor beneath a Danstoker oil-fired boiler.

Safety: Shut off the oil supply at the tank and isolate electrical power. Clean up spilled oil promptly to avoid fire risk.

• Inspect oil lines: Check all connections from the oil tank to the Danstoker burner, including flexible hoses. Tighten loose fittings and replace damaged hoses.
• Check oil pump: Inspect the burner-mounted oil pump for leaks at the shaft seal or cover. Replace seals or pump if leaking.
• Filter housing: Ensure the oil filter lid is properly sealed and not overfilled. Replace gaskets if necessary.
• Test after repair: Restore oil supply and bleed air from the system. Observe for leaks during burner operation.

Significant leaks or repeated issues should be addressed by an oil burner technician.
