Last night had a good fire going with the stove top at about 685F. I have been noticing what looks like secondary flame from the lower left hand side of the door. After the stove cooled i whipped out the old dollar bill. everywhere seems very tight except where the handle and hinges are. The bill can be pulled out with not a whole lot (maybe a little resistance) where as the top and bottom you would rip the bill in half. Is there a way to adjust this? I havent done any searching on the site about this.
