I have a lot to still learn here SO! I have had a least 5 fires in my new insert but no overnight fires apox run time 5 hours per day.On the last day after I got some hot coals going I loaded the firebox up with pine and some red oak four half splits north south then east west Cat lever down TOS temp 500 degree.I let the cat temp drop from far right to just into the active range before I loaded wood full. Then set t-stat to High ran it 5min then from a full firebox flames I set t-stat to 2 this slowed the fire down to just small flames. Now cat temp gauge goes to far right almost to the extreme right and have TOS temp 650 fan on high.So I turn the t-stat to 1 with no flames and get a back puff inside the stove so then I set it back to 2 for a little more air. Average wind speed 7 mph 40 degree outside temp with clear smoke from chimney.My question is (according to the Bk manual dont be afraid to load fire box full) does this sound like a run away stove or should I tell wife this is normal? I would like to have a cruising temp of 450-500 degree.I have seen on recent posts where wood is loaded almost to the top of the firebox. My wood is apox 2years old on the pine and oak is 7years old.
