I have a Lopi Yankee Bay insert that I've had since the beginning of this year (bought it new in January). Toward the end of last heating season, it would show a fault on the flow switch when running below a heat setting of 3 and the stove would shut down after the startup cycle. On 3 and above it would run fine. This fall I went through and cleaned everything out (including the tube for the flow switch) and it is still doing the same thing. I suspected a door gasket leak, so this weekend I went and adjusted it so that it seals better (though I suspect it still might not be perfect - it's very difficult to adjust, but that's another topic). Last night I ran it on a heat setting of 2 and it ran fine and shutdown when the thermostat told it to. When I woke up this morning it had faulted again and the glass was somewhat sooty.
The part that troubles me is that it runs fine on or above a heat setting of 3, but not below it. Does anybody have any suggestions? I am starting to think that perhaps the control board is turning the exhaust fan down too much when on a lower setting. I would think that if the air leak were that bad it wouldn't run well at all on any heat setting.
