When the firebox liner in an Enviro S50 gas stove starts to warp, discolor, or crack, the fireplace loses both its finished look and part of its heat-shielding barrier. The Enviro S50 Black Fluted Liner (50-4076) replaces that worn liner with a genuine factory part sized for the S50 firebox.

Key Benefits

• Restores the firebox's protective barrier against heat transfer to surrounding materials
• Returns the fluted, decorative firebox appearance to factory condition
• Direct-fit genuine Enviro part — no substitutions or guesswork
• Ships new in original packaging, not a reproduction

Purpose

The fluted liner channels combustion gases inside the firebox and acts as a protective barrier, limiting heat transfer to nearby materials while providing the stove's decorative interior finish.

Other Notes

Because this is a gas component tied to the firebox assembly, installation should be handled by a licensed gas technician in accordance with local codes.

While replacing the liner, it's worth inspecting other firebox components in the Miscellaneous Gas Parts category, such as glass panels and trim pieces, for matching wear.
