Hey there...My name is Lucas. We've had Fisher wood stoves for around 25 years until 4 years ago when we went to a Castile Quadra-Fire and have regretted it ever since(doesn't put out near enough heat). I got this Fisher not long ago and thru Google and the research I've done here I'm pretty sure I have a Grandma Bear Fisher stove. It has 5 bricks across the back with an 8" flue out the top AND the back. I'm unsure why there is a top and rear flue...Anyone here seen it before or know why? I've sanded and repainted the entire stove except the doors which I was planning to have sand blasted...no rust anywhere.
