A while ago I had a lot of help with diagnosing burner lockout problem with my worcester boiler. Thanks to that I eventually found out my oil was contaminated. I cleaned the oil with a marine diesel filter, swapped out the burner pump filter, nozzle and in-line filter, and all was good.
However, yesterday same thing happened. This time I knew what to look for and sure enough the nozzle and pump filter were clogged with algae.
I checked the oil in the tank and it seems reasonably clear - nothing like what it was before.
However, it occurred to me that the one thing I didn't do last time was purge the pipework inside the burner.
I've run the end of a matchstick around the inside of the nozzle housing and removed some gunk, but my thought is that unless it is thoroughly cleaned through the algae in the pipework are going to multiply even if the supply is clean.
Anyone think that is about right, and if so, how do `I purge the pipework? The burner is out on the bench now. I can undo the nut for the copper pipe that runs from the pump to the nozzle assembly, but it is narrow gauge pipe - I doubt blowing down it is going to do anything.
Can I flush through with a cleaning agent (for example)?
