[quote="Lightning"]Thanks Mike! It will take a few days for her to heal after that surgery. I've noticed that I need to let her run with more primary combustion air to maintain the same temps after a total clean out. It seems that after a few days that ash fills in the gaps between the fire bricks and around the frame which directs more air up thru the center of the coal bed.
I also made a change with the insulation behind the liners. In the past I put some on the top and bottom. This time I only put some at the top. I'm hoping this way will allow the combustion air to help take some heat from the liners to prevent warpage or burn thru again.
The insulation is needed to prevent primary air from bypassing the coal bed which is a huge issue with this particular unit and is the main reason these appliances get a bad wrap with burning anthracite.[/quote]
I think most will agree that (we) I forgot you took a combo/wood burner, and after your divine interventions your furnace can proudly proclaim " I am a coalaholic
