General Information
The Outdoor fireplace and EM 40 chimney system
is a prefabricated, refractory modular fireplace and chimney
system designed for field assembly. The system consists of
interlocking precast parts which are glued together with a
masonry adhesive.
The parts of the Outdoor fireplace and EM 40
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 Outdoor precast fireplace component is
designed for a specific part of the fireplace such that only one
means for assembly is possible.
The Outdoor fireplace requires a Outdoor refractory
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 Outdoor fireplace is available in nine sizes:
Magnum Series 28, 36, 42, 48, 60 & 72. Standard Series 36,
42 & 46. All units have either a 30” Finished opening height
(Standard Series) or a 36” finished opening height (Magnum
Series.
The EM 40 chimney system is a single module
refractory chimney system. The basic chimney consists of a
single casing block with 16” diameter flue hole. The DM 54
Chimney system can also be used. The chimney components
are field assembled using Earthcore Mortar to glue the
components to the fireplace.
The various fireplace and EM 40 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.
Important:
Due to heat and weight issues, the Outdoor Series
fireplace and EM 40 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 fireplace and chimney system.
