Product Description

Isokern Standard 46" overview

The Isokern Standard Fireplace – 46" (model 80S46) is the largest of Isokern's Standard series, a modular masonry firebox for living rooms, family rooms and outdoor patios. It is a good middle ground between a residential 36" or 42" firebox and the wider Magnum line.

The firebox is cast from natural volcanic pumice, which makes it much lighter than heavy concrete fireboxes while staying durable. It burns wood, natural gas or propane, and it can be configured as a see-through unit that opens to two rooms or to a room and a patio. A wide choice of brick colors and patterns lets you match the interior to the stone or brick outside it.

Venting & installation

Isokern fireboxes are listed only with the Isokern DM54 modular chimney or the Isokern Eco-Steel chimney, built to the height in the installation manual; see the venting recommendation on this page. Use a Fire-Lite stand on combustible surfaces. It should be installed per the manufacturer's installation manual and local codes by a qualified installer.

What to order with it

Add DM54 or Eco-Steel chimney components from this page, choose your brick, and add a Fire-Lite stand if the fireplace will sit on a combustible floor. Add a gas log set if you plan to burn gas.

FAQ
