The burnpot is the heart of your pellet stove combustion system. When it cracks, warps, or clogs beyond cleaning, heat output drops and the stove may fail to light entirely. NBK Parts 20241 is a direct-fit stainless steel replacement burnpot sized at 5-1/4 inches wide and engineered to restore consistent, efficient combustion in a long list of Whitfield, Earth Stove, and Lennox models. At 3 lbs. of high-grade stainless steel, it is built to outlast the original and is backed by a 2-year manufacturer warranty.
Whitfield, Earth Stove (Traditions line), and Lennox (Montage) pellet stoves from this era all share a common burnpot form factor. NBK Parts engineered part 20241 specifically for this family, so the mounting profile, air hole pattern, and pot diameter match the OEM dimensions. No drilling, no adapters -- remove the old pot, drop this one in, and you are back to full heat output.
Stainless steel construction resists the extreme thermal cycling that destroys mild steel or cast-iron pots over time. The alloy is selected for high-temperature oxidation resistance, meaning the air holes stay open and the pot walls stay true through thousands of burn hours.
High-temperature stainless resists warping, cracking, and corrosion through extended burn seasons. Air holes maintain their shape for consistent combustion airflow.
Engineered to match original mounting dimensions and air hole pattern for Whitfield-family stoves. No modifications required for a proper drop-in installation.
One part number covers 11-plus stove models across three brand lines: Whitfield, Earth Stove, and Lennox. Confirm your model against the fit list before ordering.
NBK Parts backs this burnpot with a 2-year limited warranty, reflecting the quality of material and manufacture used in the replacement part.
The following stove models are confirmed fitments for NBK Parts 20241. Match your stove brand and model exactly before ordering.
A worn or damaged burnpot causes incomplete combustion, excess ash buildup, hard starts, and uneven heat. Replacing it restores proper air-to-fuel mixing and heat transfer -- often the single most impactful maintenance repair on a pellet stove past its first few seasons.
Burnpot replacement is a straightforward DIY repair on these stove models. Allow the stove to cool completely before beginning. The burnpot typically lifts free of the fire pot assembly once retaining hardware is removed. Clean ash and clinker deposits from the fire pot cavity before installing the new burnpot. Confirm the igniter is seated correctly and the combustion air intake is unobstructed before relighting.
Whitfield Profile 20 FS and Profile 30 FS / INS models are compatible only within the serial number ranges listed above (7494-7495 for Profile 20 FS; 11904-11905 for Profile 30 series). Models outside those ranges may use a different burnpot diameter or air hole pattern. Verify your stove's serial number plate, typically located on the back or inside the door frame, before ordering.
To extend burnpot life, empty ash from the pot at every 1-3 bag interval, remove clinker buildup before each lighting, and use premium-grade pellets (low ash, under 1% ash content). Softer woods and high-ash pellets accelerate burnpot wear on any stainless pot.
