I recently cleaned up, painted, re-bricked and installed a Fisher Goldilocks stove. It has the air intake through the pedestal base. Wow does it heat! I don't have any cover on the air intake door and nothing really stops ash from falling in the air intake door area. Was this normal for the stove? What prevents coals and sparks from entering the door area and coming out the pedestal base? Possibly I have to add expanded steel over the air intake but that wouldn't stop any sparks or small embers?
