Choosing and fitting

When selecting a replacement oil nozzle of this type, the flow rate, spray angle, and spray pattern must match the burner data plate. The thread size must also match the nozzle holder. Nozzles are not interchangeable by flow rate alone; all parameters must be verified. Handle the nozzle by its hexagonal body to avoid damaging the tip.

Signs of failure

Using a nozzle with an incorrect spray pattern can cause sooting, flame pulsation, or unstable ignition. Debris in the nozzle orifice will distort the spray pattern, leading to poor combustion. Check the nozzle for blockages or damage if the burner exhibits these issues.
