Assembly Instructions
Optional Wood Storage Base
Note: Mason-Lite 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 Mason-Lite components
be completely covered with the mortar.
Installation of Optional Base: (You may want to watch our
installation video on our web site at www. Mason-Lite.com)
Step 1:
Set the rst course of the wood 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 and then to trace their position
on the base plate with a pencil.
After outlining the dry set pieces, remove them and apply
Mason-Lite 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. Prior to applying
the mortar to the surfaces of the blocks, use a water dampened
sponge to dampen the areas where mortar will be applied. Be
sure to put Mason-Lite Mortar on the contact surfaces of the
vertical joints where the side wall and back wall components
connect.
Figure 4 Right Side Wall shown.
For Left Side, bead opposite side.

FROM EDGES
Step 2:
Continue assembly of the second, third, courses of the storage
base side wall and back wall. Apply mortar to dampened 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.
Step 3:
After the third row of the side wall is complete, insert 28” rebar
vertically through the cells. (Figure 5) Top that o󰀨 with the fourth
row of the storage base.
Step 4:
Once the side wall assembly is complete it is necessary
to place the 3” x 3” x 1/4” x 48” Long Angle Iron across the
front face of the two sided opening before building the oven
assembly. (Figure 6)
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.
After: 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 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.
Figure 3
Figure 5

Step 6:
Align Right Side Hearth to the outline created. The overall width
should allow for an approximate gap of 1/8” between slabs
for the additional mortar to unite the remaining slab. Check
for surface atness, level if necessary. Then lay the Left Side
Hearth. This will become your base plate. (Figure 6)
Step 7:
Set the Front and Rear Dome in place. Use the damp sponge
to wet the surfaces where mortar will be applied. Check that
all is level. If you need to make adjustments, use shims. Place
one or more of these shims between the lowest wall component
and the top surface of the base plate. Once you are satised
with the degree of levelness, you can address any gap that may
have occurred with an appropriate amount of mortar. (Figure 7)
Note: Although you are cautioned to use MASON-LITE mortar
sparingly because it does have such holding power, you should
look over the oven assembly at the end and ll in any gaps,
especially joint connections, with the mortar.
Important: Adjustments can ONLY be made while the mortar is
still wet when correcting for square-ness and leveling.
Step 8:
Assemble one Dome Side. The beveled face lines up with the
inward angles of the Front and Rear Dome sides. Top surfaces
should be level. (Figure 7)
Step 9:
The rebricks for the oven cooking surface are precut. Place
rebrick tightly together using the appropriate layout shown. Do
not mortar rebrick to oor of oven or to each other. Place a
small amount of mortar under outside bricks to hold in place.
(Figure 2 & 7). Brick Panel installation sheet for adding brick
Panels to inside of oven. (not using rebrick in the oven may
lead to cracking or damage of the unit).
Step 10: Brick Panel Installation:
1) Moisten the inside of the pizza oven and the back side of the
brick panels with a damp sponge.
2) Apply mortar to the rear of each side panel and place them
against the inside walls of the pizza oven.
3) Apply the rear panel with mortar between the two sides
4) Place front panel in the front and place the pizza oven front
dome in to meet it.
5) Place pizza oven dome top on top of the dome (four side
walls) with mortar (Make sure brick panels do not raise
above dome side walls)
6) Make sure all four panels are tight and apply mortar to the
joints at the top of the panels where the dome top meets.
(Touch up anywhere additional mortar is needed).
Step 11:
Assemble the other Dome Side. The beveled face lines up
with the inward angles of the Front and Rear Dome sides. If
things are proceeding as they should be, the nished top
surface should be at and level. (Figure 9)
Step 12:
Set the Dome Top into position. (this will take two people to
do) Be sure that it is ush in every direction as you place it on
the crest of the dome wall assembly. (Figure 10)
Note: The chimney hole on the Dome Top is not centered from
front to back - it should be o󰀨set closest to the front of the oven.
Step 13:
Next assemble the optional masonry chimney. Place the front
face of the 8” Outer Chimney at and centered (left to right)
against the Dome top. (Figure 11)
Figure 7

Step 14:
Place the 4” Inner Flue starter directly inside of the 8” Outer
Chimney (4” starter is only necessary on units with more than 2’
of masonry chimney). The Inner Flue should t snuggly against
all 4 walls of the 8” Outer Chimney. (Figure 12)
Step 15:
Place the last 2 Inner Flues on top of one and other and
then slide two (2) 8” Outer Chimney directly around the Inner
Flues. With any excess mortar, or over any spots that may
need extra sealing. This will complete the assembly of your
Toscana Wood Fired Pizza Oven (Figure 13).
You are now able to nish the Pizza Oven in non-combustible
materials such as brick, stone, veneer, etc. If you are interested
in stucco please contact a local stucco contractor about an
application stucco with higher heat levels than normal.

Curing and Lighting Instructions
Curing Instructions:
First Lighting of the Toscana oven – After all construction is
completed, all elements of the oven and chimney system must
be completely dry. This means that the unit must stand without
any ring for a minimum of 28 days.
Only after that period of time can a rst lighting take place.
The rst re must be small and well-controlled, started with a
small amount of kindling. Add no more than eight pounds of
wood, preferably small logs not more than 3” (three inches) in
diameter. You will probably burn no more than three to four of
these small logs. Do not let the re burn for more than one hour.
After this rst lighting – when the oven has started to “cure” Do
not set another re for at least 24 hours.
Second Lighting – Start the re slowly and gradually as you
did with the rst lighting, but this time you can burn up to ten
pounds of rewood, probably four to ve logs that are 3” (three
inches) in diameter. With the second lighting you can let the re
burn two hours – no more.
Don’t “over burn”. If you start to use the oven and begin a
routine of “over burning,” you can permanently and unalterably
damage the unit.
Under no circumstances should you be burning household
trash, including chemicals and combustibles, cardboard boxes,
your o󰀩ce papers, scrap lumber or stray branches from your
yard, particularly pine.
WARNING: Burning of above mentioned materials will cause
an unsafe condition and will void your warranty!
Heating the Pizza Oven 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 toward the center, rear of the oven. Slowly add
small but larger pieces of dried hardwood of about three inches
(2”) 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 so as to 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.
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 continuing to feed the ames.
When the temperature of 600 - 700 degrees is reached, use
a hoe 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. Sweep the heated center
of the hearth. This will need to be done quickly so the brush
doesn’t catch on re.
The pre-heating of the oven will vary depending on the re
within the oven and if the optional oven door is used.
Cooking Pizza in your Toscana Pizza Oven:
1) Roll out your dough to desired thickness, be sure you put
corn meal under dough so dough will slide o󰀨 the pizza
peal, 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 on peel and slide into the oven. Watch pizza
carefully as it will cook quickly. Check constantly. Raise
pizza edge with metal spatula to check bottom.
4) Turn pizza every 30 seconds to a minute to ensure even
cooking throughout. The crust will begin to pu󰀨 and turn
brown. Depending on the thickness and toppings, your
pizza should cook in approximately 3-5 minutes.
5) Remove pizza with pizza peal let cool a little and cut to
desired size pieces and ENJOY!
Pizza Oven can be nished with non-combustible materials
such as Brick, or Stone. If you are interested in stucco please
contact a local stucco contractor about an application stucco
with higher heat levels than normal.
