OK, I looked it over carefully and couldn't see anything I did wrong. Then I talked to local stove stores - none had draft meters - couldn't buy one. So, I checked the barometric and set it between 4&5, closed the flap on the combustion fan a bit and it is doing fine. The folks seemed to think the 58 degree temps and 50 mph wind gusts had a lot to do with it. Guess I'll have to go on-line to get one. Can anyone suggest one? Some are staggeringly expensive.
