Been there, done that. My wife had the chimney starter rolling along nicely on my old propane gas grill (that was what it was relegated to, lol). During the transfer from the gas grill to the sidebox of the smoker, a little ember fell into a little cardboard box that had some ashes in it and came back inside to get some chicken ready. She went back outside and the house was on FIYA!!
Not good.
THIS single act is what made me make my little outdoor kitchen area below this very deck. If the flames made it up into that eave, the house would've lit up like Christmas once the insulation in the attic caught fire. The house would've been toast!
There are no hot grills that can melt siding anymore
The Kegs are located away from it as is the drop in gasser. The Traeger gets pulled out from the wall when we use it.
