I have an ICP furnace with a Becket AFG burner. Last year on a few occasions I had to wipe the cad photo cell clean to get the burner running again. It was the end of the season and I figure it just needed a cleaning.
This season I am now getting an oil smell with the burner runs then blows the hot air from the vents. I did a bunch of research and spoke to a family member who works on oil burners, to far away to visit, and did the following:
1. Inspect the combustion chamber/fire pot, it is in healthy shape. So don't think I have a cracked heat exchanger
2. Pulled the beckett and the exaust flange and cleaned them, found some loose scale but not in the fire pot.
3. Replaced the heat shield in front of the nozzle, was bent and cracked
4. Replace the nozzle.
Before all of this my service guy replaced the oil filter, etc. However he did tape off and close the exaust damper. My family member told me NOT to leave it that way so I removed the tape and it is working as it should.
Now this is all done I still get an oil smell, but not as bad. I don't know if the photocell will film up with old again, should know within a day.
Where the photo cell reside it had a layer of soot and/or thin layer of oil, not bad. I cleaned it out. Also there was soot on the nozzle and parts around it and the old tube had some oil on it as well. I don't see any leaks that I can tell in the oil feed.
Bottom line is I think the system is running to rich and does not have proper oil/oxygen mix but would love to hear if anyone else has had this problem and know of a solution. Sorry for the long post.
