Product Description

Isokern Maximus Linear 72" overview

The Isokern Maximus Linear Fireplace – 72" (model 82L72) is the size most homeowners land on when they want a true linear fire in a family room without giving the whole wall to it. Six feet of flame lines up well with a sectional, a built-in bookcase run or a 75" to 85" television above.

It is a gas fireplace built the Isokern way: insulated pumice masonry sections that assemble on site, with a burner and safety package supplied by the factory. The masonry body is what lets the Maximus sit beneath a TV or mantel with less heat migrating into the wall, and it keeps the firebox from warping over years of use.

Key features

  • 72" linear opening in a modular pumice masonry firebox
  • Isoflames burner system with remote electronic ignition
  • Factory-included Enervex chimney fan to prevent backdrafts
  • Combustion-cooling air system and automatic safety shutoff
  • Natural gas or propane
  • Optional liners, fire glass, Driftwood log set and Glass Front Kit

Venting & installation

Follow the chimney type and height in the Isokern installation manual, and see the venting recommendation on this page for the components we list with this firebox. The log set and fan need a dedicated hard-wired 120V circuit. It should be installed per the manufacturer's installation manual and local codes by a qualified installer.

What to order with it

Add the Isokern chimney components on this page. Then decide on the look: a decorative firebox liner, a fire glass color or the Driftwood log set, and whether you want the Glass Front Kit.

FAQ

What size TV works above a 72" Maximus?
Proportionally, a 75" to 85" screen lines up well; confirm mantel and TV clearances in the Isokern manual.

Does the Maximus 72" burn wood?
No. It is a gas linear fireplace for natural gas or propane.
