That sounds good. Thanks for your ideas. I think what is curious is that a couple of times it lighted normally, with the flame visible in the window and the LED coming on and the flame is quiet from the flue. Both times, the mode changed to not visible in the window, LED off, rumble from flue. And, other times when it would light, it would be in that second mode. I think the flame is burning in the wrong place, perhaps the gas pressure is too high? I made a manometer, and set the regulator pressure to 11". But, I keep thinking about my elevation (6000'). The air pressure is lower on the water column, so setting to 11" will be lower pressure in the regulator. Or, is it independent of elevation? Anyway, I tried different regulator settings last time I was messing with that, to no avail. I think I will try it again. I also messed with dial C, the temperature setting, to no avail. Anyway, this condition of two modes of the flame and the rumble seems significant to me. -- ==Leonard |
