Me again, the guy with the messy XXV full of black gunk a few weeks back. 2 weeks prior to that event we had a CO alarm go off in the hallway leading to the masterbedroom, strangely the one next to the stove did not alarm, none of the 4 downstairs either, we made the assumption we had a faulty detector. I invested into a Reed CO180 hand detector, this way I can walk around and look to see if we have a source somewhere. Today I decide to take samplings, I go in the living room where the XXV is and I felt somewhat weird, I observed a reading of 27ppm up at about 7 feet, naturally panic sets in and we open doors and windows to clear the room and all is fine. The wife ordered the XXV shutdown and wants it gone!! She does however trust the P61A. On all 3 events we had high winds and that stove is on the east wall, the 61A is on the west wall. Can the wind overcome the stove? could I have some kind of leak in the structure of the stove? I'm sure questions will come regarding the venting, I have a 24" through the wall, into a Tee, 60" up then a spout. The oak intake is next to the Tee and its Duravent PVP. In hindsight, should have got a P43, the P series is much simpler in design as it is a all welded construction versus the XXV a bolted and screwed construction meaning more gaskets. Calling the dealer in the morning, dont know where to look now, pending a good outcome the sale of more pellets for next year will hinge in balance.
