The MAGNUM Series fireplace and DM chimney system is a prefabricated, refractory modular fireplace and chimney
system designed for field assembly. The system consists of interlocking precast parts which are adhered versus glued
together with a masonry adhesive.
The parts of the MAGNUM Series fireplace and DM chimney system are precast using a proprietary mixture of
volcanic pumice aggregate and cement. It includes all the parts necessary for assembly of a complete firebox, smoke
dome and chimney system.
Each MAGNUM precast fireplace component is designed for a specific part of the fireplace such that only one
means for assembly is possible.
The firebox and smoke dome are designed to be fitted with a traditional cast iron, poker-style throat damper.
However, metal flue pipe, electronic, or chimney top dampers are options.
The MAGNUM Series fireplaces is available in 4 sizes: 28, 36, 42, and 48.
The MAGNUM Series fireplace requires a standard refractory firebrick liner be applied to the interior of the firebox.
In the 28, 36, 42, and 48 models the firebrick must be a minimum thickness of 1-1/8” on the side walls, floor, and
backwall.
All units have a (38”) rough opening height before firebrick. The only parts which differ among the available sizes are
width related pieces. All units use the same side wall pieces.
The DM chimney system is a dual module refractory chimney system. The basic chimney consists of an outer
casing block and an inner liner. It is acceptable to use mechanical assist draft systems, if the venting companies perform
the engineering calculations and make the necessary recommendations for fan size and flue vent diameter following
the guidelines of NFPA 211/2006, pages 211-13. Installation of such systems must also follow the mechanical drafting
company’s explicit installation and operation instructions.
“Smoke free” operation is not warranted nor is the manufacturer responsible for inadequate system draft
caused by mechanical systems, general construction conditions, inadequate chimney heights, adverse wind
conditions or any unusual environmental conditions or factors beyond the manufacturer’s control.
The DM chimney components are field assembled using Earthcore Adhesive to glue the components together. The
DM chimney system also includes an offset chimney block component, used to create offsets to the vertical run of the
chimney. A brick ledge component is available, designed to support chimney top brick veneer finishes. Prefabricated
masonry chimney termination caps are also available.
The MAGNUM Series fireplace and DM chimney components will be described and illustrated in the following
pages. Close attention should be paid to each component group’s specifications and installation requirements as
described in this manual. Recommended minimum overall height for the Isokern fireplace, DM, ECO-STEEL & ECO-
STEEL + chimney system for an indoor application is 18’-0” when the chimney is straight and 21’-0” when a chimney
is offset.
Maximum DM54 Chimney height without additional support needed:
57'-0"
Overall DM54 Chimney height, with proper structural support, should not exceed:
82'-0"
Intended Product Use Statement:
The MAGNUM Series fireplace and DM chimney systems are intended to burn
solid wood fuel, propane or natural gas.
NOTE:
Installation of a gas pipe must comply with the Standard for Decorative Gas Appliances for Installation in Vented
Fireplaces, ANSI Z21.60.
This fireplace is intended for use as a supplemental heat source only and is not intended for heavy use as a primary
heating system. Over-firing, abusive burning, or mistreatment will void any claims (e.g. burning construction debris or
other highly flammable material; tossing, kicking or otherwise forcing logs into the firebox).
The
MAGNUM Series fireplaces and DM chimney systems are conventional indoor or outdoor fireplaces designed
to appear like traditional masonry fireplaces. The MAGNUM Series fireplace and DM chimney system units are intended
for installation in residential homes and other buildings of conventional construction.
NOTE:
The local authority having code jurisdiction should be consulted before installation to determine the need to
obtain a permit.
