I am new here, and having problems with my stove, but have done some reading I have a quadra fire CB 1200 in the reading I have done one major discussion was cleaning and venting so I cleaned and fixed my vent the only thing I did not do was to take out the feed auger and vacuum that tube, my vent behind the stove is about 30" goes 8' and runs horizantal at a slight upward angle another 8' one other thing is the blower that blows heat into the room has been replaced I am using a two speed rather that the three speed that came with the stove for $ reasons this will be resolved shortly, But problem is the red call light is on I pushed the start button feed auger turned and dumped pellets fire starts in the fire pot the green light came on and the blue light flashed 3 times the blower I think proper term is convection blower never started green light stays on and eventually the fire goes out and we have shut down I tried another snap disc #2 but it must have been faulty as it was N.O., I live in west michigan and it's cold here now but I would like to get this resolved before we have more zero degree days, I hope yuo folks can help me and others can learn from you and me, Thanks' Steve
