Oh and let me throw this little tidbit out there for a Behmor. and in full disclosure this was NOT their fault.
Putting the roaster with the chimney part of it outside the window, the door part of it inside the window, so you can roast inside but the smoke goes outside is a B A D.... idea.
The wind sucking across it will create a suction through the thing and you WILL catch it on fire. cough cough... at least.... that's what someone once told me. No seriously though, have to be careful when we do stuff that was not intended. The 2 x 4 is a good idea, so if I use a 2 x 6 it'll be even better because it's pushing the beans closer to the heating elements right.... ummmm WRONG.... because now that it's on a large slant, all the chaff is fluffing out of the chaff holder and into the heating elements now. Ok, that one I honestly did NOT do, I could see that mess coming a mile off if I did it, I ain't dat stoopid, but this is a prime example of on how when we fiddle with stuff, we really need to think things through, and never EVER leave the roast unattended. I don't care if it's for 30 seconds. That 30 seconds can turn into 5 minutes before you know it when your CRS kicks in and now you have a problem.
CO2 fire extinguishers will put the mess out, and NOT ruin your coffee, (well hello captain obvious, at that point your coffee is already pretty F'd), but you are not spraying chemical powders all over the room or into your roaster, THAT is critical because Purple K eats electronics. Make sure you have a good PAIR of oven mitts, (No just one will not do) in case you have to do the walk / run of embarrassment to the door with a hot smoking mess. If that don't work, a METAL 30 gallon trash can with a METAL lid works wonders too. Heft the mess into that, close the cover and walk outside with it or let it cool or whatever. best part, the fire is contained so no worries about embers etc setting the carpet or mother in laws dairy queen hair doo on fire.
anyways, a bit of hijacking happened here, but the behmor is good to learn on, but folks tend to grow out of them eventually, and if you do catch the thing on fire, it IS designed to take that fairly well. A cleaning cycle and it's good to go again.
