Product Description

Isokern Ventless 46" overview

The Ventless 46" is a mid-size Isokern masonry firebox for living rooms and covered outdoor rooms that cannot easily take a chimney. Because it is vent-free and can sit on a combustible surface, it opens up placements that a vented masonry fireplace could not.

The pieces assemble with Earthcore adhesive, supplied in the right amount, and the interior is finished in cream or red firebrick in several patterns and brick cuts. An optional vent-free log set adds electronic ignition and a variable flame-height remote. It carries a limited lifetime warranty, and local code decides where vent-free gas appliances may be used.

  • Vent-free, no chimney or flue
  • Lightweight volcanic pumice construction
  • Approved for combustible surfaces
  • Cream or red firebrick in multiple patterns

FAQ

No, it is vent-free; local code still governs where it can go.

Is it heavy to install?
It is made from volcanic pumice, which is much lighter than poured concrete masonry.
