Product Description

Redefine Modern Living with the Isokern Maximus Linear Fireplace – 72"

Create a sleek, sophisticated centerpiece in your home with the Isokern Maximus Linear Fireplace – 72". Built with insulated masonry components made from pure Icelandic pumice sourced from Mt. Hekla, this fireplace is engineered for both style and performance. Pumice naturally resists rust and warping, heats quickly, drafts efficiently, and withstands extreme temperatures. It also minimizes heat transfer from one side to the other, allowing for greater installation flexibility and reduced clearance requirements.

The easy-to-assemble, modular B-Vent design makes installation simple and safe—even directly beneath a TV, mantel, or artwork. Choose between a clean, open-front look or add the optional Glass Front Kit for extra protection and a polished finish. With 12 decorative firebox liners, five fire glass color options, and an optional Driftwood gas log set, you can personalize your media bed to perfectly complement your décor.

Equipped with the Isoflames Linear Burner System and remote-controlled electronic ignition, the Maximus delivers tall, vivid flames with a seamless, integrated design. For added reliability, it includes an Enervex chimney fan to eliminate backdrafts and a combustion-cooling air system to regulate temperature and prevent carbon dioxide buildup. A built-in safety shutoff feature provides peace of mind, automatically turning off the fireplace if airflow is restricted or it’s left running too long.

Features

  • Lightweight, modular design for easy assembly

  • Masonry components made from pure Icelandic pumice

  • Approved for combustible floor installation with just 8" clearance required at the front

  • Patented Isoflames Linear Burner System for a clean, seamless finish

  • Remote-controlled electronic ignition system

  • Includes: 12" B-Vent draft diverter, Enervex chimney fan, combustion-cooling air system, safety shutoff feature, and hand-held remote

  • Optional: 12 decorative firebox liners, 5 fire glass options, Driftwood gas log set, and Glass Front Kit

  • Compatible with Natural Gas and Propane

Important Notes

  • When installing on a combustible surface, a 20" non-combustible extension is required.

  • Both the log set and chimney fan require a hard-wired 120V connection.
