Inside a gas fireplace firebox, the liner does the quiet work of containing combustion gases and blocking heat transfer to nearby materials, while also shaping how the flame area looks. This Rustic Brown Brick Liner is the genuine Enviro replacement for that component, built to fit the Enviro G42 gas fireplace and ship new in original packaging.

Purpose

The liner acts as a protective barrier around the firebox, channeling combustion gases away from surrounding materials while forming the decorative brick backdrop visible through the glass.

Key Benefits

• Genuine Enviro replacement built to the original firebox dimensions
• Maintains the protective barrier that keeps heat away from surrounding materials over years of use
• Restores the original rustic brown brick appearance without patchwork repairs
• Direct-fit for the Enviro G42, avoiding modification of the firebox

Other Notes

Because this is a gas fireplace component, installation should be handled by a licensed gas technician in accordance with local codes.

When replacing this liner, it is worth inspecting the fireplace's fire brick panels, burner pan, and trim pieces for wear, since these components sit in the same heat zone and often age together.
