I have a Lopi 1250 wood stove and im having problems finding a connector to fit the flue collar. I bought a vertical appliance connector from Rockford Chimney supplies but it doesn't sit flush in the collar due to there being a lip in the collar. Anyone ever experience this before? Suggestions? Thanks!
