I recently purchased a wood stove and would like to set it directly into my fireplace. My question is can I just extend the stove pipe up to the fireplaces flue or do I need to extend the stove pipe through the flue up into the chimney. the flue is obviously not round so how can I fit it or adapt my current fireplace flue to allow the stove pipe to extend through and into the actual chimney. Is there some kind of adapter-cover plate? I have a new home with a masonry exterior chimney. Stove pipe from stove is 8" Stove is a Coalbrookdale Darby. http://stoves-direct.org.uk/stoves/multifuel/darby.html Thanks any feedback would be apriciated.
