Hi all. I just replaced the catalytic combustor and refractory assembly and all the gaskets, everything went great & the stove is back together. Except one bolt. I took off the lower right hand acorn nut (looking at the back of the stove) and the bolt on the inside has fallen into the stove. I cannot see a way to get to it from the inside. 
Any suggestions?
Thanks.
