Being fairly new to the offset world I have a question for the more seasoned stick burners . I am cooking between 240-260 and I have my firebox door wide open and exhaust is wide open. Is it normal to have to run with the door open. My fire is small as I use a stick about every 25 mins that is roughly 1.5 inches in diameter. Started my fire with half a chimney of lump. Is this how I should expect to run my low and slow cooks?
