Looking up your stove on the web I found this: Dislikes: Small firebox, only 6 hours before coals are dead (maple, ash). Thin inner fireplates that crack apart. Rear firebricks crack immediately (I built a shield from an old stove part to cover them). Manifold is poorly designed such that cast nipples holding the stainless plate pop off when it warps, negating any clean burning. I repaired the existing one by drilling through and tapping for bolts instead of the bevel head screws to keep the two parts together (works great). I also have to prop up an old stove part to protect the inner fireplate from cracking even further. I think for the next stove I will investigate steel instead of cast iron... Anything to do with your problem?
