EFM SPK 600 boiler brush size?

seldenr Member Posts: 1
I just bought a house that has an EFM SPK 600 boiler and the unit seems to be working properly but the sellers were unable to provide any real maintenance records. I'm just going to go ahead and replace the oil filter, and clean it out as best I can on my own.

Does anyone know the appropriate sized tube brush for this boiler?

    It’s really a job for a properly trained professional with combustion equipment. The fact that there are no maintenance records means you really should have a pro make sure it has the correct nozzle and all the combustion parameters are correct.
