Keep your Enviro pellet stove burning cleanly and efficiently with the correct OEM-style burn pot liner. Part 50-587 (also cataloged as NBK Parts 20253) is a direct replacement for the burn pot liner in select Enviro models, restoring proper combustion geometry and protecting the burn pot assembly from ash buildup and heat damage.
The burn pot liner sits inside the burn pot and takes the brunt of repeated high-heat combustion cycles. Over time, liners crack, warp, or erode -- leading to uneven pellet burn, increased clinker buildup, and reduced heat output. Swapping in a fresh liner is one of the most cost-effective maintenance steps you can take to restore stove performance.
Enviro part 50-587 is designed specifically for the models listed below. Using the correct liner ensures the air-hole pattern aligns properly with the burn pot, which is critical for achieving the right air-to-fuel ratio during combustion.
Designed to match the original liner geometry for listed Enviro models -- no modification required.
Fits EF2, EF3, EF3Bi, Meridian, and Windsor pellet stoves. Verify your model before ordering.
Weighs just 0.3 lbs, making it easy to handle during routine stove maintenance and cleaning.
