My upstairs Englander woodstove only has an 8'x6" chimney pipe, but it
normally draws well when air leaks into the house downstairs and out through
the stove.
But it finally stopped working after the chimney became completely clogged
with creosote after several years of slow burns in the well-insulated
upstairs area.
I have a Magic Heat exchanger with its fan in the middle of the 6' vertical
pipe above the stove.
As of 1984, at least 7 companies made 6" retrofit heaters:
