I recently purchased a magnolia 2015 wood stove to replace my regency 1100. I swapped the stoves out snd did my first few slow burn fires to set it up. Then after this it seems to burn out of control the air damper on the bottom has zero affect on the stove. I loaded the stove to do a trial with 8 pieces of cord wood and with tbe sir damper closed completely it burned through it in less than 3 hrs with a white hot fire. Since i have a straight run from stove top to chimney top. There are no restrictions my draw is so good it will suck a tissue out of you hand. I added two elbows to slow the draft. That did slow the burn rate down to a managable level. But tbe air control still does nothing. I crawled under the stove confirmed it is still hooked up. I put my leather gloves over it blocking the air entirely and still no change. Any ideas would be appreciated.
