Product Description

Isokern Magnum 42" overview

The Isokern Magnum Fireplace – 42" (model 82042) is the size that fits most homes: a 42-inch modular masonry firebox that suits a typical living room, a primary bedroom sitting area or a patio wall. It gives you a true masonry fireplace without the weight of a site-built one.

The volcanic pumice construction keeps the sections light, insulating and resistant to heat damage. You can burn cordwood, or set it up for natural gas or propane with an Isokern gas log configuration that includes electronic ignition and a remote. Brick comes in full, split, soap and strip formats in several colors.

  • 42" Magnum pumice masonry firebox
  • Light enough to assemble without heavy equipment
  • Wood, natural gas or propane
  • Remote electronic ignition on gas setups

Venting & installation

Isokern lists the Magnum 42" only with its DM54 modular chimney or Eco-Steel chimney, built to the manual's height; 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

Choose chimney components, brick, a Fire-Lite stand if needed, and a gas log set for gas operation.

FAQ

Can it go in a bedroom?
Its size suits a bedroom sitting area; check local code for wood or gas fireplaces in sleeping rooms.

Is a see-through version available?
The Magnum gas log setups are for single-opening installs; call us about see-through layouts.
