NFPA 31  Flue liners in masonry chimneys for venting

Question asked by delawareinspector on Mar 2, 2016

Does NFPA 31 require a stainless steel chimney liner when connecting a new oil fired heating appliance to an existing masonry chimney?.

Does the efficiency rating of the appliance factor into this (i.e. oil burner with 84% or greater need SS liner)?
