Just to clarify to the wood stove guys. This is a high efficiency wood stove with multiple layers of brick, that never gets over a few hundred degrees on the exterior. The hottest I’ve ever seen the flu get was 475 degrees. Most gun powders have an ignition temperature of 800+ degrees. I could pour a pound of powder on it, and nothing would happen. I understand your concern, but it’s going to be ok. I promise.
