Oil Heat, PT.2

摘要

The previous chapter began the presentation of oil-fired machines. We started at the business end of the burner gun/discussing the fuel nozzle. This chapter completes that discussion: Fuel Nozzle Problems. Explain to your service customers that a good way to minimize fuel nozzle problems is to replace the nozzle periodically, usually on a yearly basis. It is definitely not a good idea to try to clean a fuel nozzle.
