Still really enjoying this furnace. Besides the firewood being a never ending battle it has saved my family a lot of money (not including a insane amount of labor)
Any owners know the purpose or function of the rear fire bricks with the holes in them? I try and keep them clear I want just wondering when they are working (call for heat/no call for heat)
Pilot air....they help keep a flame when the unit is closed down. The air holes are unregulated, and always bring in air whether the damper is open or closed.
