even if you followed all the safety and clearance requirments ,could you imagine if you got her running strong for several hours fully loaded with glowing/flaming hardwood and that heat buckled the loosely assmebled sides ,they give out and it collapsed apart right onto your floor in a fiery blaze ,im not sure a small fire extinguisher could even put that kind of situation out ,what if yo u went inside the house for a phone call or to make a pot of coffee and it happend without you knowing ?
