Possible Causes

How to Fix / Troubleshooting
Safety: Turn off power and fuel before opening burner compartments.
- 1. Check fuel line and filter: For Energy Kinetics oil boilers, inspect the oil line for air leaks at fittings and replace the oil filter if dirty. Bleed air from the pump according to burner manufacturer instructions.
- 2. Inspect venting and draft: Ensure the chimney or vent is not partially blocked and that barometric damper (if used) moves freely. Remove visible obstructions only if accessible and cool.
- 3. Clean combustion head: Remove the burner drawer assembly and clean carbon from the head and end cone. Reassemble carefully.
Persistent flame failures require a technician to check draft, combustion air, and burner setup with instruments.
