Acid rain indoors?

Has anyone ever experienced this? For several years, my parents have noticed a strong sulfur odor around their Van Wert stoker. Their service people have been there several times for cleaning, resealing the chimney, etc yet the odor persists. Last night while building a fire for them (timer went, but that’s a different issue) I noticed that the gasket on the upper part of the ash door completely deteriorated. This got the chemist in me thinking about what I thought were 2 unrelated problems.

Of late, they’ve also been having trouble with corrosion & failure of the copper cold water lines around the boiler. Hot lines, no problem.

Is it possible that the gaseous sulfur compounds are disassociating in the condensate on the cold line and forming sulfuric acid? This in turn is causing the corrosion of the copper.
