Shut down the stove on Sunday for weekly cleaning. After waiting for the stove to go through it's cool down process; approximate 45 minutes. I started with the burn pot, emptied and scraped it all out into the ash pans and sifted through the fines to break up any leftovers. Now the stove has been off for about hour and fifteen minutes, start the vacuum the ash pans out. Few minutes later got a really weird smell in the house, so I took the shop vac outside and took the lid off and ran my hands through the fines and ash in the bottom and did not find anything smoldering. But half an hour later wife came home and said that the vacuum on the front porch was smoking. Sure enough, went out and either sucked up an ember in the hose or motor and stuck there cause the bottom of the motor and filter has been completely melted off the lid.
