I am purchasing a home and am having trouble finding specific codes under 211. My question is related to how stainless steel chimney liners should/should not be installed in an older masonry chimney for a solid fuel wood stove. I was told that the current SS liner is not insulated and may not be safe. Additionally, there is an oil-fired forced air furnace with a separate flue that is also missing a lining. I'd like to know the specific code numbers to look at so I may use them in my price negotiation for the home. Please note I am in Vermont which has no adopted state codes for single-family homes.
