Does anyone know where the air comes into a Lopi Declaration stove? I am running my stove right now and if I keep the doors cracked a bit it runs great. If I close the doors completely the fire is starved for air. I have had a fire going for 2 and a half days now so I have a couple inches of ashes built up in the bottom of the unit. Does the air come into the firebox through the bricks on the floor of the combustion chamber? Does anyone else know why if I crack the doors it runs fine but if I close them it dies out starving for air. Obviously I have all air controls wide open.
