General Information
The MAGNUM replace and DM 54 chimney
system is a prefabricated, refractory modular replace and
chimney system designed for eld assembly. The system
consists of interlocking precast parts which are glued together
with a masonry adhesive.
The parts of the MAGNUM replace and DM 54
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 rebox, smoke
dome and chimney system.
Each MAGNUM precast replace component is
designed for a specic part of the replace such that only one
means for assembly is possible.
The rebox and smoke dome are designed to be
tted with a traditional cast iron, poker-style throat damper.
However, chimney top dampers are an option.
The MAGNUM replace requires a standard
refractory re brick liner be applied to the interior of the
rebox. Fire brick must be a minimum thickness of one and
one-eighth inch (1-1/8”).
The MAGNUM replace is available in six sizes:
twenty-eight (28), thirty-six (36), forty-two (42), forty-eight
(48), sixty inch (60) and seventy-two (72).
All units have a thirty-eight inch (38”) rough opening
height before re brick. The only parts which differ among
the available sizes are width related pieces: the base plate,
rebox back wall, front and back smoke dome components,
and the smoke dome top plate. All units use the same side
wall pieces.
The DM 54 chimney system is a dual module
refractory chimney system. The basic chimney consists of an
outer casing block and an inner liner with a fourteen inch
(14”) diameter ue hole. The chimney components are eld
assembled using Earthcore Mortar to glue the components
together.
The DM 54 chimney system also includes an
offset chimney block component, used to create offsets to
the vertical run of the chimney. A brickledge component
is available, designed to support chimney top brick veneer
nishes.
Prefabricated masonry chimney termination caps are also
available.
The various MAGNUM replace and DM 54
chimney components will be described and illustrated
in the following pages. Close attention should be paid to
each component group’s specications and installation
requirements as described in this manual.
Important: Due to heat and weight issues, the MAGNUM
Series replace and DM 54 chimney system installations
require that the system be built upon a non-combustible
concrete slab with no wood underpinnings supported to
footings with concrete or steel and designed to carry the total
weight of the Isokern replace and chimney system.
The Fire-Lite application of the MAGNUM Series replace
is designed to be built upon a combustible oor system and
will also require a design that will support the total weight
of the Isokern replace and chimney system. The FTF-
13 or equivalent chimney system only must be used with
the Fire-Lite application. Please refer to pages 56-81 for
installation instructions.
Recommended minimum overall height for the
MAGNUM Series and DM 54 chimney system for an
indoor application are 18’-0” when the chimney is straight
and 21’-0” when a chimney is offset. Maximum overall
height is 82’ - 0”, however, installations over 54’ - 0” will
require additional support.
