One of my customers was tech school welding department. So I was telling the welding instructor about my project I was going to build and he told me I should bring it in and let the kids work on it. Free labor.... Why not. Well I think the way they connected the tanks to the fire box is keeping it from getting a good draft to my smoke stacks. I am not getting enough heat to the tanks. And even with the heat damper taken off and large holes left in the door as soon as I close the door it kills the fire.
Think it would help if I had pipes coming out closer to the top of the box angled into the tanks?
