LOCATION
This oven can be placed on a suitable counter surface. Allow 4" minimum bottom clearance and 6"
minimum clearance on all sides of the oven. Additionally, appropriate operator access is required to
the front and back of the oven, and 27" minimum clearance on either side to allow removal of the bottom
deflector pan. Do not place anything on top of the oven.
This oven must not be connected directly to a ventilation system as this would cause uneven heating
and reduce operating efficiency. If ventilation is desired, install the oven under a suitable hood that
will not result in a direct pull of air through the oven.
Overall dimensions are 29" wide x 641/4" deep x 193/4" high.
INSTALLATION CODES AND STANDARDS
The oven must be installed in accordance with:
In the United States of America:
1. State and local codes.
2. National Electrical Code, ANSI/NFPA-70 (latest edition). Copies may be obtained from The
National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.
In Canada:
1. Local codes.
2. Canadian Electrical Code, Part 2, CSA Standard C22.1 (latest edition). Copies may be obtained
from The Canadian Standard Association, 178 Rexdale Blvd., Rexdale, Ontario, Canada M9W1R3.

BEFORE FIRST USE
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING.
Clean all stainless steel parts with a soft cloth moistened in mild detergent and warm water to remove
any shipping dust and the protective oil film. Refer to CLEANING in this manual.
WARM-UP
Turn main power ON. Adjust dial settings for: Top Heat - In, Bottom Heat, Top Heat - Out, and Belt
Speed to medium position 5. Allow about 7 minutes for warm-up.
OPERATOR TIPS
Depending on settings for Top Heat - In, Top Heat - Out, and Bottom Heat, product can be baked on
top and/or bottom. Product is placed on the chain conveyor at the front and moves through the heated
oven chamber to the exit tray at the rear.
— 5 —
Maximum product size is 18" wide. Moving product through the 24" long baking chamber requires
about 6 - 8 minutes, depending on the belt speed. Belt Speed 1 is slowest (for more doneness); Belt
Speed 10 is fastest and results in lighter toasting or less doneness.
CAUTION: DO NOT turn speed to 0 during warm-up or baking. This could damage the conveyor.
Products will require some experimentation to achieve the appropriate balance of heat control and
conveyor speed. Each time the controls are changed, allow about 5 minutes for the temperature to
stabilize.
COOKING GUIDELINES
The suggested settings, pages 6 and 7, are guidelines only. They are based on Vulcan-Hart lab testing
and may differ from your products. Prove your products and recipes by testing them in the oven to
determine repeatable settings before full operation.
For consistent results, allow the temperature to stabilize in the oven before sending products through.
Baking temperatures and belt speed settings depend primarily on whether the pizza dough is par-
baked or raw.
Par-Baked Dough pizza products are generally prebaked from 50 - 90% done and come in different
thicknesses. These pizzas require less bottom heat, while the belt speed can vary depending on
variety and number of toppings. High-moisture toppings can require more top heat to evaporate excess
moisture before completing the browning/melting process in baking. Sauce should be spread evenly
to the outer edge of the pizza crusts.

Raw Dough pizza products use fresh-prepared dough (or thawed from frozen). These doughs are
either run through a "sheeter" or "tossed" and then "proofed" in a proofing cabinet before baking. After
the dough has been mixed and "scaled" into uniform balls (portioned), a "sheeter" is used to stretch,
flatten, and shape the dough. Dough may be passed through the sheeter one or more times to achieve
proper thickness and shape. "Tossing" the dough means manually stretching, flattening and shaping
the dough. "Proofing" means the dough has been allowed to rise for a period of time in a proofing
cabinet under controlled temperature and humidity. Raw dough pizza requires high bottom heat and
lower top heat settings to properly bake the crust. Dough may or may not be "docked" before baking.
"Docked" means the dough was rolled with a spiked rolling pin which punches holes in the dough,
preventing the dough from rising during baking. The number of toppings has little to do with the heat
settings. Again, sauce should be spread evenly to the outer edge of the pizza crust.
Results are similar with seasoned pans or screens; however, bottom heat should be reduced when
baking in aluminum foil deep-dish pans because of their high level of heat transfer.

CLEANING (Fig. 2)
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING. WAIT FOR OVEN
TO COOL.
CAUTION: Avoid using abrasive powders or pads on the outside of the oven; these cleaners
may damage the finish.
NEVER clean any electrical appliance by immersing it in water. Using a soft clean cloth and detergent
and warm water, clean the exterior of the oven daily after use. Reconnect the oven. With the heaters
— 7 —
OFF, turn the conveyor speed to 5. Using a plastic abrasive pad, carefully wipe the conveyor belt in
a horizontal motion (side-to-side) to remove baked-on product. Wipe the conveyor in the same manner
with a hot damp cloth. When the open link of the conveyor is accessible at the front, turn the main power
switch OFF. WARNING: DISCONNECT ELECTRIC POWER.
1. Lift up to remove the top cover and top reflector.
2. Slide the bottom deflector pan out the side.
3. Remove the rear deflector by lifting over the supports.
4. Relax the conveyor chain by pressing down on the top of the chain and disconnect at the open
master link. When reconnecting the chain's master link, the weight of the chain holds it in place.
5. With the chain removed, the middle deflector pan and conveyor support rods can be removed.
6. Lift up to remove the exit tray; its support legs must be removed from the side pins.
7. Clean parts in a sink with warm soapy water, rinse, and wipe dry.
8. Reassemble all parts before returning oven to operation.
