Assembly Instructions - Optional Base With Optional Base
Note: Earthcore mortar can be troweled over the face of a joint
where it has squeezed out while setting components. It is not
intended that the exposed faces of the Isokern components be
completely covered with the mortar.
Installation of Optional Base:
Step 1:
Set the ISO’ven base plate in a full bed of Earthcore
Mortar at on a proper support foundation. (Figure 1).
Do not set the ISO’ven base plate so that it is in span. Level the
ISO’ven base plate by oating it in a bed of Earthcore Mortar
to full bearing against the underlying support surface.
Step 2:
Set the rst course of the storage base back and side
walls into place.
It may be convenient to dry set the rst course of
side and back walls 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 rst layer of wall components can be set directly into
mortar already applied to the proper areas on the base plate.
(Figure 1)
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 and third courses
of the storage base 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.
Once the side wall assembly is complete it is
necessary to place a steel angle minimum 4”x 4”x 3/8” across
the front face of the two sided opening before building the
oven assembly. (Figure 4)
Notch the ends of each sidewall equal to the thickness of the
steel as shown. Each end of the steel angles must bear fully at
least 3” onto the side wall assembly. (Figure 2)
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.
Figure 1
Figure 3
Figure 2
Step 4:
When all of the ISO’ven side wall components are
set, check the top surface of the storage base 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 ISO’ven storage base plate. (Figure 3)
Any gap created under the wall components during the Shim
leveling process must be lled with mortar to full bearing
against the base plate.
SHIM IF REQUIRED
TO ACHIEVE
CORRECT HEIGHT

Step 5:
Make sure that the storage base assembly has been
set level and square. Adjust as required while the mortar is
still wet.
Make a nal inspection of all contact joints in the
storage base assembly to be sure they are properly sealed.
Fill any and all gaps in the assembly as necessary, with the
approved mortar.
Step 6:
The ISO’ven comes with an eight inch (8”) thick
support beam assembly, a four piece component group
that is to be assembled on top of a steel lentil, (in front as
shown) set on the side walls of the storage base.
The support beam assembly consists of two long
beams and two short support beam side pieces.
The two long support beams are identical in shape,
size and length, equal to the width of the ISO’ven model
that they serve.
The support side pieces are designed to sit on
the storage base side walls between the front and the back
support beams. Each of the support side pieces is designed
specically for its own side of the unit. When properly set,
each support side piece ts ush with the outside face of the
storage base sidewall so that its interior bottom edge aligns
with the interior angle of the storage base side wall that it
sits on. (Figure 5)
It is necessary to place a steel angle, supplied by
the customer, minimum 4”x 4”x 3/8” across the front face
of the two sided opening before building the oven assembly.
(Figure 4)
One support beam sits ush with the front of the storage
base, spanning the storage base opening. Properly placed,
the second long support beam is to sit on top of the storage
base back wall and ush with it . These components both sit
on their narrow base so that their beveled face points down
and into the storage base interior. (Figure 5)
Be sure to mortar all support beam components to
the top surfaces of the storage base.
Mortar the contact surfaces of each support side
component where it meets the front and back support beam
assembly components.
Step 7:
Place the shelf pieces, # 91 & # 21 on top of the
support beam assembly or client designed base so that the
edge sits ush with the back walls. Morter into place.
IMPORTANT: If the ISO’ven base is utilized, client
should trim shelf to no more than 9” in front of unit
without adding support to ledge from underneath.
(Figure 7)
Step 8:
Set the back wall of the Isokern material ush with
the rear of the shelf unit in a bed of Earthcore mortar ensuring

Note: If the ISO’ven base is not required, client should
build a base approximately 40 inches high and a depth of
no less than 35” to set the table top ISO’ven on.
(Figure 6)
Step 9:
Cut a piece of Inswool to t and lay against the back
wall of the Isokern back wall as shown, then place the back
wall inner liner against the Insboard.
Note: DO NOT MORTAR OVEN LINER OR INSWOOL
TO ISOKERN MATERIAL.
Step 10:
Place a row of brick on the Isokern material ush up
against the back wall inner liner. (Figure 8)
There is no need to mortar brick in place. Butt brick tightly
against each other and back wall liner.
Step 11:
Run a bead of high temperature caulking along the
outside edges of the back wall liner. Rest the side wall liner
against the back wall edge.
(Figure9)
Repeat on other side. Place Inswool up against outside of side
wall liners as shown.

Step 17:
Finally, seal gap between oven liner front wall and
Isokern front wall completely with ECI mortar.
(Figure 13)
Step 18:
The thermometer has a 6 1/2” or 9” stem. A hole
should be drilled into the upper right quadrant of the oven
walls, just thick enough for the stem to be pushed through.
The face of the thermometer can be counter sunk into the
Isokern material or left a bit raised. The length of your
thermometer stem will be determined by your facing material
and the look you wish to achieve. The tip of the probe should
either penetrate the oven slightly or penetrate the liner of
the ISO’ven. Use the shorter stem for thin , exterior facing
applications such as stucco. Use the longer stem for thicker,
exterior applications such as brick or stone veneers. After
insertion of the thermometer, mortar into place. (Figure 14)

ISO’ven Curing Instructions:
It is critical that the Isokern elements in the ISO’ven
assembly be dry before ring of the unit. Moisture left in
the ISO’ven components from exposure during storage and
shipping, as well as moisture from the installation phase,
must be eliminated before the unit is put to its intended use.
The rst step in reducing the ambient moisture is to
be sure that the completed ISO’ven rest totally in a dried-in
setting for a minimum of 14 days after construction of the
unit is complete.
The next step in curing the ISO’ven is to be sure that
the rst three or four res are of short duration. These res
can take place after the rst week of installation. Make small
kindling res to about 200 - 300 degrees to dry out any last
moisture from the unit.

10
Heating the ISO’ven for cooking:
Start the rst re slowly with a small
amount of paper and kindling (small dry wood splits
or twigs) stacked in a crossed or teepee fashion
(shown) toward the center, rear of the oven. Slowly
add small but larger pieces of dried hardwood of
about three inches (3”) to four inches (4”) diameter.
The temperature will begin to rise in your
oven however it may take about 15 minutes to begin
a faster temperature ascent.
NOTE: Take care not to feed your re too fast and
smother it As you add more wood, a temporary
decrease in temperature my occur. This is normal
and as soon as the new wood begins to burn, your
temperature will rise again.
The next step is to ensure that your re
continue to build and heat the entire oven. When a
temperature of about 500 degrees is reached, spread
the coals throughout the oven (toward the rear of the
oven) while continung to feed the ames.
When the temperature of 600 - 700 degrees
is reached, use a hoe or paddle to rake all the coals
together to one side of your oven. (either side is
acceptable). You are now ready to cook in the center
and on the side without coals.
Cooking Pizza in your ISO’ven:
1. Roll out your dough to desired thickness,
and place on top of the screens provided in your
accessory kit (or purchased on your own). Let stand
about 5 minutes to let the dough rise.
2. Spread desired pizza sauce in a thin,
even layer on top of the dough. Cover with toppings
as you wish.
3. Place pizza screen on peel and slide into
the oven. Watch pizza carefully as it will coook
quickly.
4. Turn pizza every 30 seconds to a minute
to ensure even cooking throughout. The crust will
begin to puff and turn brown. Depending on the
thickness and toppings, your pizza should cook in
approximately 3-5 minutes.
