The Chimney Pack is used when your chimney stack has
been lowered beneath your roof line, and you are required to re-line the
remaining chimney stack with a flexible liner. This happens when your existing
masonry chimney becomes unsafe. This Chimney Pack allows you to build the
chimney off the top of the existing stack, and through the roof. All the parts
you require are included in the Chimney Pack, but the correct length of flue
liner must be ordered seperately.
