General Information
The STANDARD fireplace and DM 54 chimney
system is a prefabricated, refractory modular fireplace and
chimney system designed for field assembly. The system con
-
sists of interlocking precast parts which are glued together with
a masonry adhesive.
The parts of the STANDARD fireplace 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 firebox, smoke dome and
chimney system.
Each STANDARD 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. How
-
ever, chimney top dampers are an option.
The STANDARD fireplace requires a standard refrac
-
tory fire brick liner be applied to the interior of the firebox. Fire
brick must be a minimum thickness of one and one-eighth inch
(1-1/8”).
The STANDARD fireplace is available in three sizes:
thirty-six inch (36”), forty-two inch (42”) and forty-six inch
(46”). All units have a thirty inch (32”) rough opening height
before fire brick. The only parts which differ among the avail
-
able sizes are width related pieces: the base plate, firebox 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 refrac-
tory chimney system. The basic chimney consists of an outer
casing block and an inner liner with a fourteen inch (14”) di
-
ameter flue hole. The chimney components are field 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 verti-
cal run of the chimney. A brickledge component is available,
designed to support chimney top brick veneer finishes.
Prefabricated masonry chimney termination caps are also avail-
able.
The various STANDARD fireplace and DM 54
chimney components will be described and illustrated in the
following pages. Close attention should be paid to each com
-
ponent group’s specifications and installation requirements as
described in this manual.
Important:
Due to heat and weight issues, the STANDARD
Series fireplace and DM 54 chimney system installations re
-
quire 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 fireplace and chimney system.
The Fire-Lite application of the STANDARD Series fireplace is
designed to be built upon a combustible floor system
and will also require a design that will support the total weight
of the Isokern fireplace and chimney system. The FTF-13 or
equivalent chimney system only must be used with the Fire-Lite
application. Please refer to pages 47-55 for installation instruc-
tions.
Recommended minimum overall height for the
STANDARD Series and
DM 54 chimney system
with an
indoor application are 18’ when the chimney is straight and 21’
when a chimney is offset. Maximum overall height is 82’ , how
-
ever, installations over 57’ - 0” will require additional support.
