Any Heritage owners ever seen your stove do this? Is this normal? I have a 5 year old Heritage (top exit) connected to Excel Ultrablack dual wall stove pipe to our Excel stainless steel chimney. In the stove pipe run I have a damper at 15" and above and a Condor flu gas thermometer at 25".
Before going to bed last night I loaded my stove with 4 logs, which I've done many times before. The stove was hot before I loaded it. I let the wood catch and shut the damper and reduce the air to about 1/8 open (all with in 2 to 3 minutes) and let run for about like that for about 30 minutes. After the 30 minutes I checked the flu gas thermometer and it read 900F and rising. So I shut the air intake to 0 open and flu gas kept rising to 1100F. The re-burn tubes were cranking red hot. The center stone temperature only got up to 400F maybe a little warmer but I've gotten the stove much hotter in the past. So at 1100F and rising I started to get a bit nervous since I have not seen temps like that before and not been able to close the stove and get it back in control. Last night the only thing I could do was to completely block the air intake with some paper and wait until the fire to die out which took a while. Once the fire was out I then unblocked the air intake and resumed the burn with no problems. This mornig I re-loaded the stove and everything seems in controllable.
Any thought are appreciated.
