I am new to wood burning, but I have just acquired an Old Mill wood stove that I am going to be installing for use as my primary heat source. I have never installed a wood stove and I had a few questions regarding the topic. Firstly, the chimney pipe: Is there any benefit to running the chimney pipe through the wall instead of right out the roof? My wood stove has the opening for the stove pipe on the top, if that has any consequence. Either way, it seems to be my understanding that the triple wall chimney pipe is frequently used for either installation, would that be correct? Secondly, the fire bricks: Should these all fit tightly in the stove? My stove has flanges to have fire bricks on the bottom, sides, and rear of the stove. Are the bricks supposed to be cut to fit snugly, or is the fact that they are a little loose no big deal? I read another post in the forum about the bricks and one gentleman seems to say you don't need them, but since my stove manufacturer has provided the flanges for them, I believe that using them would be the best idea. Any information would be greatly appreciated, looking forward to using the site.
