You must live near me. We had insane winds sat. night and rain, today was amazing, sunny and real warm. I was debating on letting the stove go out but decided to just crank it back as far as I dared and not have it go out. I heard of others letting their stoves simmer at 190 degrees, so I decided to try. I had my MKII open 3/4 of a turn and the stove ran at 200-225 all day, with a barely detectable glow in the coals. Tonight, I opened the bottom door for 5 minutes, and the thing was glowing red and ready to roar again. Pretty neat. I can see the Harman claim of 24 hour burns is certainly not far fetched.
