Before using, the door swung open freely unimpeded. After just 2 fires, the door gets impeded at around 85 degrees upon opening, then rubs when opening further until it goes beyond the 90 degrees then moves freely again. Is this caused by heat expansion as that is what I assume. I hope this doesn’t affect the stove’s efficiency with constant use. Maybe the outset part of the door hinge should be a touch thinner to allow for expansion. I await any reply and if any other owners have the same problem. Thx
