I just bought a Fisher Mama Bear. I was hoping someone could tell me something about the plate on the back. I thought that it might be a place for a fan due to it has what looks like a vent hole on the bottom of the stove. This appears to be an add on but I'm not sure, any ideas would be appreciated. Thanks!
