What can cause an oil boiler burner to lockout?

A burner lockout can occur as a result of no oil or a leak in the pipeline. Another cause of burner lockout can be from contaminated oil. This contamination can be caused by one of the following:

• water ingress into the oil tank from a missing cover
• a damaged tank from condensation
• sludge which can occur due to the growth of micro-organisms at the water fuel interface in the tank
• or rust from a metal oil tank corroding.

Your oil supplier will be able to assist you with cleaning your tank and flushing through the oil lines.
