Doing some maintenance on our Napoleon 1900 and looking for some advice. Our 1900 will be 4 years old this fall, but we only burn on the weekends.
1. Last night I removed the secondary Manifold Shield. I know it needs replaced as it is sagging in the middle, and blocking some of the air holes in the burn tube. One of the bolts sheared off, so not sure best way to handle that. Guess I will drill a new hole and try to tap it. Old hole still has half the bolt in it. Any other suggestions? Is a standard stainless steel bolt sufficient to handle the heat inside a stove?
2. How do you know if you need to replace the Airwash Shield & gasket?
Someone said I should replace the Airwash shield when I replace the manifold shield, is only reason I'm even asking about it. Ours looks okay, and stove burns okay (no air leaks). The manual tells you to check it at the end of each burning season for deterioration. Ours is dirty as the rest of the inside, and has a little surface crust in places (from creosote?), but I don't see anything I would call "deterioration." The bolt heads that hold it on look a little crusty, and I anticipate those possibly shearing off if I try to remove them, so I'm hesitant to even try if I don't need to.
3. Baffles. How worn can you let them get before replacing?
Ours have normal flaking/wear and a couple of 1/4" deep gouges. One has a crack, but crack doesn't go all the way through. Overall, they are still solid, no big chunks broken off or anything. Being 2" thick, a couple of gouges doesn't seem like a big deal. Would furnace cement stick and last on these?
