I can't recommend anything but what efm calls for....8" chimney.
I know for a fact that many use smaller chimneys because they have good draft. It is usually permissible to have a chimney 1 inch less depending upon the firing rate, but for me, it's the official "line".

I believe my chimney tile is 8x8, but the existing thimble is for a 7" smoke pipe for my oil boiler...it's the smoke pipe I would have to reduce...I imagine I could chop it out but I wouldn't want to if it wasn't necessary...

I run 6" and can't wait to get a bigger chimney. Seems I get a wiff everytime the stoker starts. Sort of like it Scott
