This is my first year with a pellet stove and with my new Harman P35i insert. The insert pushes up against a metal bracket and a gasket. The metal has two small rectangular openings, one for the exhaust and one for the OAK. The opening the for exhaust is smaller than the opening on the stove outlet and I am wondering if it would be wise to remove some of the metal on the bracket so it matches up with the stove exhaust bracket or does the stove need some back pressure or should I leave well enough alone? I hope my description is good enough to explain my question.
Thanks
