Concentric Flue - Cuttable extension pieces
When cutting a concentric flue extension piece,
care must be taken to ensure that the inner section
is always cut 10mm longer than the outer section to
allow sections to be joined correctly.
Do not cut all the way through both sections at the
same length. Cut the outer section first and then
the inner section 10mm longer.
