I have found a build up in my stack that is tested as being primarily sulfer. i am burning #2 fuel oil that is by factory testing low in sulfer. What could be causing this? Low stack temp? Condensing flew gas?
There is an economizer on the stack could this be causing part of the problem? I am under the opinion the sulfur is from the fuel and have sent a sample to a indipendent lab for testing.
