Keep your pellet stove burning cleanly and consistently. The US Stove 891249 is a direct OEM replacement agitator rod designed specifically for the US Stove 6100 and 6220 pellet stove models. Built from stainless steel for heat resistance and long service life, this rod stirs pellets in the burn pot to prevent clinker buildup and maintain steady combustion -- one of the most common wear items in any pellet stove.
The agitator rod is a critical component in pellet stoves that use an agitation system to break up ash and clinkers in the burn pot during operation. When the rod bends, breaks, or wears out, fuel feed becomes inconsistent, combustion suffers, and error codes or shutdown cycles often follow. Replacing a worn agitator rod is one of the simplest, most cost-effective maintenance tasks an owner can perform.
The 891249 is a factory-spec part from United States Stove Company, matched exactly to the geometry and material requirements of the 6100 and 6220 stove platforms. It is also cross-referenced and sold under the NBK Parts number 20239 -- so if you have found this part listed under either number, you are looking at the same component.
Engineered specifically for the US Stove 6100 and 6220 burn pot assembly -- no modification or trimming required.
Resists high combustion-zone heat and the corrosive byproducts of pellet ash better than mild steel alternatives.
Matched to the 6100/6220 burn pot dimensions to ensure proper agitation geometry and clearance.
Listed as both US Stove 891249 and NBK Parts 20239 -- confirms authentic sourcing regardless of which number you searched.
The agitator rod operates in a high-heat, high-ash environment every time your stove runs. Watch for these signs that replacement is due:
Replacing the agitator rod on the 6100 and 6220 series is a straightforward task best performed during a routine cleaning cycle when the stove is fully cooled. Remove the burn pot per your stove's service procedure, extract the old rod, and seat the new 891249 in the same position. No special tools are typically required.
This part is designed and sold as a fit for the following US Stove models:
If you are unsure whether your specific stove variant uses this rod, compare the part number on your existing agitator rod to 891249, or verify through your stove's parts diagram that your model uses a 9-inch agitator rod in the burn pot assembly.
