Enviro E20 Gas Fireplace Insert

The Enviro E20 is a compact gas insert that brings a log fire look to fireplaces with a modest opening. It comes with its log set, a convection fan, and a liner, so the pieces that make it look and feel like a fireplace are already in the box. It burns natural gas or propane.

This is the millivolt version, with a standing pilot you light using a piezo ignitor. That keeps the controls simple and familiar. Enviro offers brick, fluted, and porcelain liners if you want a different look inside the firebox, and surrounds are optional accessories you can add to finish the front.

What Makes the E20 Different

• Logs, fan, and liner included. You get the log set, a convection fan, and a liner with the insert.
• Made for smaller openings. The minimum fireplace opening is 24 1/4 inches wide at the front and just over 18 inches tall.
• Simple millivolt controls. A standing pilot with a piezo ignitor keeps operation straightforward.
• Liner choices. Swap in a brick, fluted, or porcelain liner to change the look of the firebox.

Ownership & Maintenance

The convection fan waits until the insert has warmed up, so it won't run while the unit is cold. We provide support after the sale.

We'll measure your fireplace, confirm the E20 fits, and plan the liners and installation. See more gas fireplace inserts or stop into our Auburn, Brunswick, and Yarmouth showrooms.
