How to Fix / Troubleshooting

Safety: Turn off the oil supply at the tank and isolate electrical power. Avoid open flames and sparks near spilled oil.

Inspect oil lines: Check flexible and rigid oil lines to the Viadrus burner for wet spots or drips. Tighten fittings gently; do not overtighten.
Check burner compartment: Look for pooled oil in the burner tray. Clean up with absorbent material and dispose of properly.
Service burner: An oil burner technician should replace the oil nozzle, check pump pressure, and adjust air settings using a combustion analyzer to ensure clean burning.
