My brother installed a Buck 18 in a Heatilator E39 with a solid SS chimney liner wrapped in in 1/2 insulation, it was a straight shot into the top of the insert.Will a 6 inch 2100 degree insulated liner fit into the 8" prefab chimney? Does the liner need to be insulated?
You would be better off going with a smaller insulated. 30 foot is a good stack height that might warrant a 5" chimney.The prefab chimney is located centrally and not outside till it exits the roof. It is a 30 foot straight run . Would an uninsulated 6" liner be ok?
I'm putting in a woodstove, NOT an insert. It will be in front of the fireplace.
