I have a previous post about the wood stove I just got, but in removing the old stove insert we found that the liner was oval at the bottom, and we can’t get it to fit or to re round it, most likely done to get past the flue. I’m trying to man handle the liner, it collapsed a few inches and we were unable to raise it back up. Are there any ways around this oval end here? The dealers I purchased the wood stove from said I may be able to use connectors for the bottom and connectors for the top instead of trying to raise it back up. The only issue is I’m not sure how to get the connector on the bottom.
