: Thanks HeatPro - but I didn't quite follow...
: Sorta sounds like if we were to just block gas from sections, then the heat applied to the boiler is uneven, therefore stressfull?
+++ Yes, it is stressful.
So are you saying that if we remove burners we could re-space them so there isn't uneven heating?
+++ You will notice from the post that is NOT said, so you are saying that, which is incorrect. There is no way to respace existing holes.
However, by removing sections, you have less passages.
: My unit has 6 individual burners in it, and I assume that each is about 25k btu, giving me the current total of 150k btu. If we could reduce it to 4 burners that would be approx 100k?
+++ True
Is this a relatively easy task for a technician, or maybe not due to the 35 year age of the unit?
+++ If it was in brand new condition, you are still confronted by the need to assess the capabilities of any tech. Anyone who has repaired sectional boilers would have a good chance of doing it, when so inclined.
