2 story drafty house, 25 foot SS lined chimney.
No matter how hot the fire is, or what stage it is, if I open the door the gasses change from going up the chimney, to into the house.
I'll have a ragging fire burning, watching the secondary burn roll around the baffle and almost to the chimney outlet. To me obvously there is a dedcent draft if this is happening.
If I open the door it's like someone flipped a switch, and closed the chimney.
Even when its just a bed of hot coals, and I go to stir them up with the "poker" I'll get some sparks floating out of the door and straight up.
Any thoughts?
I have even tried opening the front door, windows near, and it hasn't changed a thing.
My only thought is, the insert is inside an old "heat form" or "heatilator" fireplace. There are openings in the brick face about a foot above the stove where I can look through and see the liner. I don't have a bottom block off plate, just the upper one. Is it possible a small draft could be escaping?
