Feeling the Heat
I can say yes with about 95 percent certainty. If it's full throttle firebox full of flame and I shut the thermostat, it's take a couple minutes to lose all flame I feel. Otherwise, yes, it'd be pretty quick to snuff completely out and ride like a champ for hours and hours...why?If the flue-to-stove fitting is leaking you will not smell any smoke at that point because it is in a negative. The stove's firebox is not in a strong enough negative to overcome the creosote lateral creep. A very small leak at that joint (or any joint) will "spoil" or greatly reduce the total draw resulting in the "smoke smell" effect.
At any point in the burn, can you extinguish the flames by closing the thermostat?
