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.

The customer's oil supplier will be able to assist with cleaning the tank and flushing through the oil lines.
