I have an Alasksa Channing 3, bottom vent, power venter (with manometer). When I got home this morning Co detector was going off in basement. When I went down to check it out, smelled sulpher and the Co ppms were high. Everything looked good at stove, had a good draft (-.5) feeder system seemed fine, temperature on stove was 300 degrees (where I left it). Then I took the lid off hopper and the top of the coal was soaking wet? and this is where the strong smell of sulphor was comming. I dug into coal and it was warm and did see a little smoke. I immediately shut stove down and ventilated basement.
Well, I am thinking it is a gasket that has failed and allowed air and heat up into hopper.? I know there are diffent gaskets (strongback,grate gasket 2' x channel gasket and feeder housing rope gasket. Also hopper gasket. (I am reading from manual)
This stove is in its 6th year of operation without a single problem. I did feel gaskets at start of year and seemed soft (ok). Any ideas of what gasket failed?
