Product Description

Isokern Maximus Linear 120" overview

The Isokern Maximus Linear Fireplace – 120" (model 82L120) is the flagship of the Maximus line: a ten-foot-wide gas linear fireplace built from Isokern's modular pumice masonry rather than a steel box. At this width it is meant for spaces where a standard fireplace would look lost, such as double-height great rooms, lodge-style living areas, hotel lobbies and large open-plan homes where the fire has to read from across the room.

What separates the Maximus from a typical steel linear unit is the body. Pumice masonry heats quickly, resists warping and keeps heat from moving through to the outside of the firebox, which is why Isokern can list it for installation under a TV, mantel or artwork. A factory-supplied chimney fan and combustion-cooling air system are part of the package rather than add-ons.

Key features

  • 120" linear format built from insulated Icelandic pumice masonry components
  • Isoflames linear burner with remote-controlled electronic ignition
  • Enervex chimney fan, combustion-cooling air system and automatic safety shutoff included
  • 12" B-Vent draft diverter and hand-held remote included
  • Natural gas or propane
  • Can be finished open-front or with the optional Glass Front Kit

Venting & installation

The Maximus ships with a 12" B-Vent draft diverter and an Enervex chimney fan, and its chimney must be the system and height specified in the Isokern installation manual; see the venting recommendation on this page before ordering chimney parts. Plan for hard-wired 120V power at the firebox. 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 listed on this page (DM54 components or the Eco-Steel alternative) for your chimney height. Isokern also offers decorative firebox liners, fire glass colors, a Driftwood gas log set and the Glass Front Kit to finish the media bed.

FAQ

Is the Maximus 120" a wood-burning fireplace?
No. It is a gas linear fireplace that runs on natural gas or propane through the Isoflames burner.

Can I mount a TV above it?
Isokern designed the Maximus for installation below a TV, mantel or artwork; follow the clearances in the installation manual.

Does it need electricity?
Yes. The log set and the chimney fan both need a hard-wired 120V connection.
