I have been monitoring flue temps with my ir thermometer and everything seems real good, the stove seems to be more efficient with the extended baffle in place, i am pleased with that, i like to keep the stove stemps around 500 to 550 and it seems to hold there very well and for much longer, my only problem now is some of the seasoned wood i have became wet and am trying to dry it out, its 3 year seasoned white, black and red oak, also maple, i have been splitting it and placing it in the log rack next to the stove, some of my tarps got blown over and my wood got wet, hopefully this will remedy that
