Hello, Not sure where else to go at this point as my local stove shops are no help at all. I recently revived an old Timberline stove from my father to put into my home. We got it all nice and pretty and into my basement (VERY slowly they really re heavy little things). We got gasket in it, checked the baffle, cleaned it out some, got some new paint on it and put in on some tiles so it wouldn't be touching the concert floor. Now for our confusion, when we tried to connect the 6" stove pipe it wouldn't fit into the 6" thimble/opening/what ever you call it on top of the stove. We used tin snips to try and allow for more flex in the crimped end of the pipe, but that just lead to having rather large openings between the stove and the pipe. What are we missing to get it connected?
