Question:

A local stove dealer said I only have to run a chimney liner 5 feet up into the chimney (and stuff insulation around it) - given that I have a long- straight chimney- and that flu liners are WAY expensive- is there a reason- other than proper draft- for running the liner all the way to the top?



Answer:

With pre-fab fireplaces you should usually run to the top--even though some pre-fab inserts tell you that less is acceptable. You should do this because
A. The chimney with your fireplace is not class A and was not designed for a woodstove.
B. The smaller chimney drafts better and is easier to clean
C. A liner is an extra margin of safety.
D. If you were ever to have a chimney fire- and warp your Pre-Fab's original liner- it would be extremely difficult to replace--the liner will keep it contained
E. Mercedes Benz's are expensive today ! Line it to the top (do it yourself to save some $$- you sound handy)- or if you have the bucks- keep the economy going by paying the installer.
