We got our new Hearthstone Heritage installed a few weeks back. Well we are now in the cold weather and I guess we have fantastic draft. Issue. My hubby loaded the stove last night and closed the damper in the pipe and left the damper open a smidgen in the front. He was awaken to the smell of really warm stove...you all know the smell....went downstairs and the stove top was up to 600 degrees. Today he loaded it again and closed both dampers down all the way. Later I checked the stove and the top was up to 550 degrees. We are afraid this high heat is going to damage the stove. Any suggestions to keep the temp lower or is this Okay??
