FUNCTION AND PURPOSE

• This equipment is intended to bake fresh dough and par-baked pizza and flatbreads – one at a time. It is not intended to bake frozen pizza, deep dish pizza, or cook raw food or raw toppings.
• It is intended for use in commercial foodservice operations that serve pizzas, but that also have other menu items. It is intended for occasional, not continuous use. It is not intended for pizzerias.
• It is not intended for household, industrial, or laboratory use.

CLEARANCE AND ENVIRONMENT REQUIREMENTS

• Do not place on surfaces or near walls, partitions, or kitchen furniture unless they are made of non-combustible material or clad with non-combustible heat-insulating material.
• Toasters must not be used near or below curtains and other combustible materials.
• Do not place the toaster adjacent to a heat-producing appliance.

Ventless Operation

• This oven is UL-tested and verified for ventless operation under the following conditions:
• For use with pre-cooked foods such as pizza toppings, sandwiches and melting cheese
• Not for use with raw and/or fatty proteins such as skin-on or bone-in chicken, hamburger meat or sausages
• Note: Local codes may apply. Approval for ventless operation is subject to the local Authority Having Jurisdiction (AHJ). Please contact your AHJ for more information.

SET UP

1. Place the oven on a hard, flat, stable surface.
2. Install the legs. Two people are 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.

FROZEN/FRESH DOUGH HANDLING TIPS

• 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 the top of the dough balls with a non-stick cooking spray, then cover with a layer of freezer paper.
• Refrigerate overnight.
• 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. The 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 prevent 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 the 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.

• NOTICE: Dark metal or seasoned metal screens and pans perform best. Shiny metal or aluminum foil will reflect heat away from the pizza and prevent browning.

1. Test the settings by placing a sample pizza into the oven.
2. Monitor the baking process and adjust the temperatures and conveyor speed to prevent the pizza from burning.
3. Evaluate the results.

Bake

1. Adjust the top and bottom heat control settings and conveyor as needed to achieve desired results. Allow time for the oven to adjust to new heat settings before placing a pizza on the conveyor.
