Paul Meyer said:I now have dirty glass all the way across instead of the "V" shape. Is there some conduit or tube I should inspect to find out if it needs to be cleaned? I have been running at minimum thermostat settings for a long time, with lots of crunchy creosote in the stove, nothing in the chimney.
The V on mine fills in with kind of a copper colored film when I am burning stuff that isn't perfect at low burn this time of year. Maybe try letting it burn a little longer before you close the bypass/turn it down to deal with the crunchy stuff?
