Step 2: Set the first course of the firebox back wall and side walls
into place.
It may be convenient to dry set the first course of side
wall and back wall into place on the Isokern base plate and then
to trace their position on the base plate with a pencil.
After outlining the dry set pieces, remove them and
apply Earthcore Mortar to the areas traced on the base plate
where the side walls and back wall are to sit. By doing this, the
first layer of wall components can be set directly into mortar
already applied to the proper areas on the base plate.
Be sure to put Earthcore Mortar on the contact surfaces
of the vertical joints where the side wall and back wall
components connect.
Step 3: Continue assembly of the second, third and fourth courses
of the firebox side wall and back wall. Apply mortar to the top
of each layer of wall components, set the next course above into
place. Be sure to mortar all vertical joints of the side wall to back
wall connection when setting each component to its mate.
Look for some mortar to squeeze out along the joints of
all contact surfaces as a sign that the joint is thoroughly sealed
with the approved mortar.
Step 4: When all of the firebox wall components are set, check
the top surface of the firebox for level. If necessary, adjust the top
surface of the box assembly for level by inserting a shim between
the lowest wall component and the top surface of the base plate.
Any gap created under the wall components during the
Shim leveling process must be filled with mortar to full bearing
against the base plate.
Step 5: Make sure that the firebox assembly has been set level
and square. Adjust as required while the mortar is still wet.
Make a final inspection of all contact joints in the
firebox assembly to be sure they are properly sealed. Fill any and
all gaps in the assembly, as necessary, with the approved mortar.
Step 6: Take the Catalytic assembly out of the box and verify all
components are in tact and Yellow EPA hangtag is attached to the
combustor. The Catalytic kit should contain a Catalytic
Combustor, and two (2) metal angle support brackets.
Note: Remove hangtag from combustor and place in a secure,
permanent location. Retention of this hangtag by the owner of
the fireplace is mandatory. If ownership changes, hangtag should
be given to the new homeowner.
Step 7: Insert support brackets so that the largest angled portion
slides into the side wall cavity toard the front of the sidewall
slots. The smaller angles should be facing upward toward the
inside of the firebox.
