It is a new unit, just fired it up last Thursday. We were adjusting settings alot in the beginning, but have let it run at 4 and 4 for about 4 days now and just bumped the air up to 5 yesterday. It is very clear that there is an ash ring around the back and sides, but upfront it is red and burning right up the edge, so a lot of partially burnt coal is coming off.
What other detail can I give you?
Oh and we are dumping the fines every day, not always when it's running, but they are getting consistently dumped. Maybe an air hole issue? How can I check that?
On the subject of the thermostats, we thought about switching them so that the one in the addition was the main, but I don't think that will help the cold upstairs, because the dining room and upstairs are on the same zone and the dining room stays a consistant 70 with very little heat running. I think all that would do is make it feed the coal a lot more to keep the addition (which is very poorly insulated) warm and we would lose a lot of efficiency. We might want to take the main thermostat out of the dining room and put it in the living room, which is not quite as tightly sealed and then it will control the overall temperature a little better. But, I think we'll have to see how the current setup does in the very cold weather before we make any thermostat changes.
Thanks again for the advice!
