A worn or cracked firepot is one of the most common reasons a pellet stove loses ignition reliability and combustion efficiency. This is the genuine QuadraFire replacement EZ Clean Firepot, part number 812-3351 (also sold as NBK Parts 20085), designed specifically for the CB1200 and 1200i Classic Bay Insert pellet stove series. Restoring your firepot brings back clean, consistent burns and protects the surrounding firebox components from secondary heat damage.
The firepot -- sometimes called the burn pot -- is the heart of any pellet stove. It holds the fuel during combustion, channels combustion air through its perforations, and takes the most concentrated heat abuse of any component in the appliance. Over time, the cast metal warps, cracks, or accumulates clinker buildup that no amount of cleaning will fully clear. When that happens, airflow becomes uneven, ignition becomes inconsistent, and efficiency drops noticeably.
The QuadraFire EZ Clean design addresses this with a firepot geometry that makes ash and clinker removal faster between burns. Replacing this part yourself is straightforward -- no specialized tools required -- and significantly less expensive than a service call.
Shaped for quick ash and clinker removal between burns, reducing maintenance time and keeping airflow consistent.
Direct replacement engineered to factory specifications for the CB1200 and 1200i series -- no modifications or adapters needed.
Fits CB1200 units from 1997 through present production, including the CB1200-C and CB1200M-MBK variants, plus the 1200i Classic Bay Insert.
