Harman SF-2500-A to a 6 inch SS chimney?

[HarryH]

I have a chance to pick up what looks like a seldom used Harman SF-2500-A Wood/Coal Furnace.

The manual says a 7 inch flue is required, I have a 6 inch stainless steel chimney, and a 7 inch (6 3/4 ID) masonry chimney.

I'd like to put it where the ss chimney is, as it's a straight shot, up and through the roof.

To use the masonry chimney, will require a 90 degree elbow, and possibly cutting a new hole through the concrete wall, and into the chimney (and liner)

Thought?
Advice?

Thanks
Harry

I am going to put in a Harman 260 boiler i am going to put it into a 6" stainless chimney because i can not fit anything else and hope for the best. Let me know how yours works.
