This assembly is a composition of high temperature refractory silica that can resist temperatures as high as 3200deg Farenheight. If you are having trouble keeping a consistent burn temperature or having a tough time controlling the draft, even with the damper closed, you may have cracks and corrosion in the assembly itself that could result in a fire that has a difficult time "settling down". Too much draft will burn through wood much faster and send heat up the chimney rather than in the home and may cause your stove to overheat.
This refractory is crucial to maintaining a clean, efficient, and believe it or not, environmentally friendly burn. If you are seeing symptoms like the ones mentioned above, the first place to start would be to re-gasket the doors and ash pan with the Resolute Acclaim Gasket Kit.
This would be the best place to start before disassembling the entire stove. If, after replacing the gaskets, you are still fighting to control your draft replacing your refractory assembly would be a logical next step. Keep in mind that over time the Upper Fireback.
Can also corrode away which will then no longer make a seal to the refractory assembly where it has broken down. When the damper is opened, most of the flue gases enter the upper fireback and out the stove pipe rather than going through the assembly itself, but that is rarer. Replacing the refractory assembly with this new Vermont Castings 1602497A combustion package may be just the trick to get your wood stove working like new again.
