I previouly started a thread (#10203) on 12/29/2008 and since then I have new information yet still no resolution. Any help would be greatly appreciated.
During my research I have found I am not the only person with this issue:
1) A local chimney contractor has seen many cases of 'red staining' issues .. he claims it is not the chimney deteriorating but is unsure of the source of the red.
2) Selkirk (a chimney manufacurer) had enough inquiries that they worked with a lab and believe the red is a result of the sulfer in the oil and/or corrosion caused by the sulfer. However even good quality oil has sulfer.
3) I reviewed the web site thread and pursued its leads but got no solution:

4) Several major full oil service companies in RI have of yet been able to resolve this issue.
5) Carrier believes it is not there boiler and have tried to wash their hands of the matter.
6) Beckett has seen similar 'red' issues but is unsure how to resolve my problem.
I am actively working with my present oil service company .. they have been very cooperative and want as much as I do to find out how to resolve this issue.
To summarize where I am today, I find small 'black' non-magnetic specs around the smoke pipe a top my boiler and on my roof. The specs location seem to imply they are generated in the boiler and thus eliminate the chimney component. The specs get blown out the top of the chimney flue when the boiler is on, end up on the top of the roof and lip of the chimney and then the morning dew adds enough moisture to leach the red from the spec. The flue cap is not dripping red so this does not seem to be a chimney flue condensation issue.
So .. I am still looking for a solution. The source seems to be the black specs. My thoughts are reducing the sulfer content of the oil or a better burn of the fuel in the boiler might be a step in the right direction. But I am not sure how to do either of these things?
Suggestions are always welcome and thanks for any feed back.
