When the firebox lining in an Enviro pellet stove cracks, warps, or burns through, heat starts escaping past the combustion chamber instead of radiating into the room, and the stove can feel like it is working harder for less warmth. The Enviro EF-047 (also listed as EF047) is a genuine replacement firebox liner with insulation that replaces the worn liner in compatible Enviro EF3 and Vista Flame pellet stoves built before January 1, 2008.

Purpose

This liner forms the interior wall of the firebox, containing combustion heat and protecting the stove's outer shell and components from direct exposure to flame and high temperatures.

Key Benefits

• Restores proper heat containment for consistent room heating
• Helps the stove burn at its designed efficiency instead of losing heat through a compromised liner
• Includes insulation matched to the original firebox design
• Genuine Enviro part, ships new in original packaging

Other Notes

Make sure the stove is unplugged, fully cooled, and cleared of ashes before removing the screws that hold the existing liner in place.

While the firebox is open, it is worth inspecting the burn pot, gaskets, and any nearby insulation panels for wear, since these components tend to degrade around the same time as the liner.
