A bolt is stranded behind the lower fireback.I need HELP! Thirty-one degrees last night! Where are all the Mr. Fix-Its when I need 'em??????? I've attached the page from the manual that shows the parts I'm referring to. There are five acorn nuts as you are facing the back of the stove, two on the left: one upper, one lower. You can see the holes for them in part #3, "back panel." There are three on the right: The top one caps a bolt that holds the damper housing (#7) in place. The bolt is easily seen inside the stove, the top of the bolt is not hex-shaped but paddle shaped, holding the damper housing. that bolt is #9 on the exploded diagram. It is not the bolt in question, I'm just getting you oriented. The next bolt down on the right (still not my bolt, I'm still getting you oriented) is a hex bolt, #12 on my diagram. It goes through the fireback clamp (#11), through the upper fireback, and out the back of the stove, where, again, it is covered by the middle acorn nut on the right side of the back of the stove. The third bolt is my bolt. It appears to be another #9, which is shaped like the upper one on the same side, but I have never seen the other end of it since, as I said, it is lost inside the stove. It goes through the lower fireback, out the back of the stove, and is covered by acorn nut #3, which I have. Unfortunately, the bolt is not visible to me, as it is covered by part #15, "rear air tube," which is in there quite firmly and does not want to come out. I can't see any screws going through the "rear air tube" on the diagram. It might just be wedged in. If it's just a matter of levering the rear tube out so I can get to the bolt, great. But the way these stoves fit together, there could be another part holding it in place. I don't want to get a lever in there until I'm sure that's what I should be doing. I don't want to break something. So back to my original question: how do I get to that bolt. Part B of my question is, If I can't get it out can I bolt it from the back just to fill that hole. It won't be actively securing the lower fireback, but there does not appear to be a millimeter of jiggle room in the rear air tube, so maybe it's enough, I don't know.
