so I was at work today. Wife called and said there was smoke coming from the EF2 hopper, there was no flame in the burn box and the stove was off. It was out of pellets. So I am figuring that when it ran out of pellets for some reason the stove shut down before the fire was completely out and done smoldering. So the smoke back up into the augur and out the hopper. This is my best logical guess. Everything seems to be working fine. Is there a reason that a stove would shut down before it was supposed to?
