SET UP
FROZEN/FRESH DOUGH HANDLING TIPS
1. Place the oven on a hard, flat, stable surface.
2. Install the legs.Two people required. Have one person lift one end of
the oven while the other person installs the legs. Repeat for the other
side of the oven.
NOTICE: Legs must be installed. Failure to install the legs will
restrict airflow and cause the oven to overheat.
3. Install the load and unload trays to match the conveyor direction.
The load tray slants toward the conveyor. The unload tray slants
away from the conveyor.
The following are general tips. Follow any instructions specific to your
brand of dough or recipe.
• Remove the wrapping from frozen dough balls.
• Place the dough balls a few inches apart, into a proofing box or on a
sheet pan.
• Lightly spray top of the dough balls with a non-stick cooking spray,
then cover with a layer of freezer paper.
• Refrigerate over night.
• Only remove enough dough balls from the sheet pan to
accommodate what you will need for a few hours.
• Sprinkle flour, cornmeal or Pizza Crisp onto the surface on which
you plan to roll out the dough.
• Roll the dough, starting from the center and working your way to the
outer edges. Turn the dough as you work toward the outer edges to
maintain a round shape.
• Use a rolling pin, dough press or dough sheeter to form the dough
to the desired size and thickness.
• Place the flattened shell onto a dark metal or seasoned pizza screen
or pan.
NOTICE: Fresh dough pizzas must be baked on metal pizza
screens or pizza pans. Do NOT put fresh dough pizzas
directly on the conveyor. Dough will stick to or fall
through the conveyor.
NOTICE: Do NOT use paper pizza pans in this oven. Paper pizza
pans will burn and could create a fire hazard.
NOTICE: Dark metal or seasoned metal pans perform best. Shiny
metal or aluminum foil will reflect heat away from the
pizza and preventing browning.
PIZZA ASSEMBLY TIPS
• Spread the sauce, starting from the center and moving toward the
outer edges of the crust to ensure a uniform thickness of sauce.
Leave an inch of space to the outer edge of the crust to allow the
crust to brown. Spreading sauce too close to the edge prevents the
crust from browning.
• Spread out high moisture content toppings, such as vegetables.
High moisture toppings will prevent the surrounding areas from
baking until ALL of the moisture has evaporated.
