Keep your St. Croix pellet stove burning efficiently with this genuine OEM burnpot grate weldment. The burnpot grate is a high-wear combustion component -- over time, the repeated heat cycling and ash accumulation cause warping, cracking, or burnthrough. Replacing it on schedule restores proper airflow and combustion performance. This is the exact factory replacement for Afton Bay, Hastings, Prescott EXL, and Prescott EXP models.
The burnpot grate weldment sits at the heart of your pellet stove's combustion chamber. It holds the pellet fuel while allowing combustion air to flow up through the burn zone. When the grate deteriorates, you may notice incomplete combustion, increased ash buildup, uneven flame, or fault codes related to low heat output. Swapping in a fresh grate resolves these symptoms quickly.
This weldment is sold as a single assembled unit -- no fabrication or welding required. It is also cross-referenced under NBK Parts number 20475, which is how many HVAC suppliers list this component.
Manufactured to St. Croix factory specifications. Part number 80P52980-R ensures a direct, no-modification fit in compatible models.
Arrives fully welded and ready to install. No additional hardware or assembly steps needed before fitting into the burnpot.
Built from steel designed to withstand repeated combustion cycles and the elevated temperatures inside an active pellet stove firebox.
Fits four St. Croix pellet stove models: Afton Bay, Hastings, Prescott EXL, and Prescott EXP. Confirm your model before ordering.
The burnpot grate operates under extreme and repetitive thermal stress. Each heat cycle expands and contracts the metal, and fuel ash can be mildly corrosive over time. Most pellet stove manufacturers recommend inspecting the burnpot grate at the start of each heating season and replacing it when visible warping, cracking, or thinning is present. Running a damaged grate reduces combustion efficiency and can cause pellet jams or auger faults.
Replacing the burnpot grate is a straightforward maintenance task that most stove owners can complete without professional service. General steps common to St. Croix burnpot grate replacement:
