The following assembly instructions identify the parts
by name, part number and the placement of each part in
the assembly process.
NOTE:
At all component placement, be sure to mortar
all contact surfaces with Earthcore adhesive. Check for
complete sealing of each contact joint while assembly
progresses.
1.
Apply Earthcore adhesive to the joint between each
baseplate part and set the base plates in a full bed of
Earthcore Adhesive on a level support surface. See page
18 for supporting floor system.
(Figure 15)
. Do not set
the base plate so that it is in span. Refer to pages 8-15 for
part dimensions.
Flush Hearth:
If the design preference is for a “flush hearth” the base
plate can be omitted from the assembly and the firebox
walls built directly on a minimum 4" concrete support slab.
The fire brick floor of the firebox is then set directly to the
concrete support slab. This makes the fireplace finished
fire brick floor approximately one and one-half inches
(1 1/2”) above the top of the concrete support slab.
Raised Hearth:
If the design preference is for a raised hearth (floor
of the fireplace elevated above the room’s floor), then the
base plate can be set on a noncombustible platform that is
built up to the desired raised hearth height on the concrete
support slab. See page 18.
When calculating raised hearth height be sure to allow
for the three inch (3”) thick base plate plus the one and
one half inch (1 1/2”) thick fire brick floor in addition to the
height of the platform.
For all “raised hearth” construction where concrete
blocks are used to create the raised platform, it is necessary
to use the base plate. Be sure to Earthcore adhesive the
concrete block platform together. CMU used for base plate
support should be rated ASTM 90.
Whether a flush hearth or a raised hearth is installed,
the combustible floor in front of the fireplace must be
covered with a noncombustible hearth extension set tight
against the fireplace front and extending at least 30 inches
out from the finished fireplace and at least 12 inches
beyond the sides of the fireplace opening. See page 16 &
17
(Figure 11)
.
2.
Set the first course of the firebox side walls and back
walls into place.
(Figure 16 & 17)
NOTE:
It may be convenient to dry set the first course of
side walls and back walls into place on the Isokern base
plate and then trace their position on the base plate with
a pencil.
