Full Oil Boiler Servicing
Every system should be serviced once a year by an OFTEC engineer to maintain its safe and efficient performance. An oil boiler full service will involve:
- Remove the oil burner
- Replace blast tube “o” ring
- Remove, clean, and inspect the blast tube
- Replace the atomizing nozzle
- Check/test solenoids
- Test and clean photocell
- Check the ignition transformer and ignition leads
- Test and adjust electrode settings, replace if necessary
- Replace oil flex hose
- Reassemble the burner and test; adjusting oil pump pressure and air settings to the manufacturer’s recommended instructions
Our engineers will thoroughly inspect your system, checking for signs to see if the performance has been compromised.
Oil nozzles can wear out over time and cause poor fuel regulation. In addition, soot deposits can form in the heat exchanger, reducing the efficiency of the heat transfer process.
If our engineers spot these or any other issues, we can get to work restoring your boiler to a better condition.
