We live in a condo unit (ca 1200 sqft; gas; copper baseboard); these were built as apartments in the mid-1950's, and so each pair of units shares a chimney.
So, in looking to replace, we're finding there are issues with this shared chimney. Has any of you worked through a similar situation?
One plumber consulted said a building inspection would be needed, 1st we've heard this; will have to call town hall on T. Why should this need inspection?
One contractor for EK sys 2000 suggests a 5" stainless liner. But would that limit our neighbor's choices, i.e., if they got a system with a liner? By condo rules, we'd be responsible for any trouble the liner would cause. Would lining the whole chimney (10 or 11") be better? (The current unit next door is Utica, MGB1252H, from early '90's; currentlly they share a t-joint at the bottom.)
(Side venting has problems with important windows & vapor plume, as discussed in another thread.)
Any wisdom about chimney sharing? Thanks.
