Keep your Hot Blast pellet stove burning efficiently with a fresh replacement liner. The 40258 is a direct-fit, heavy-duty steel liner that serves as the front liner on 1400-series stoves and the rear liner on 1500-series stoves -- one part that covers two critical positions across a wide range of Hot Blast models.
The firebox liner in a pellet stove takes a constant beating from high-cycle combustion. Over time, liners warp, crack, or burn through, allowing heat to escape into the cabinet instead of your living space. A degraded liner also disrupts airflow patterns inside the combustion chamber, leading to incomplete burns, clinker buildup, and higher fuel consumption.
The US Stove 40258 is the factory-spec replacement for this wear item. It is constructed from heavy-duty steel rated for the sustained temperatures found inside Hot Blast combustion chambers. At 3 lbs, it is a solid, substantial component -- not a thin stamped shell.
Functions as the front liner for 1400-series Hot Blast stoves and as the rear liner for 1500-series stoves. One SKU handles both roles.
Built from thick steel to withstand sustained pellet combustion temperatures cycle after cycle without warping or cracking prematurely.
Fits 13 confirmed Hot Blast model variants including 1400, 1500, 1537G/M/Q, 1557M, 1600, 1600G/M, 1602, 4.5, 5.6, and 7.1 series.

Pellet stove liners are consumable wear parts. The intense and repetitive thermal cycling of a pellet stove -- igniting, burning, cooling, and re-igniting multiple times per day across a full heating season -- causes steel components to expand and contract thousands of times annually. Signs that your liner needs replacement include:
