PREHEATING
NOTE: Preheating will vary etween Ultra Rokite
shelf and steel shelf ovens.
DA steel baking shelf set to 600_F (316_C) will
preheat in 30Ć40 minutes. An additional 20 minĆ
utes should be allowed for the oven to soak up
heat.
DA Ultra Rokite shelf set to 600_F (316_C) will
preheat in approximately 1 hour and 10 minĆ
utes. An additional 20 minutes should be alĆ
lowed for the oven to soak up heat.
For preheating the oven both the UPPER and
LOWER HEATER switches (4 and 5) should be set
on HIGH. When the oven has been preheated as
recommended for steel or Ultra Rokite shelves the
heater switches may be set to the desired level.
VENTING THE OVEN CAVITY
An oven cavity slide vent for venting moisture is
furnished above the upper heaters and must be
operated from inside the oven.
BAKING
The ideal temperature for baking pizza will vary deĆ
pending on the type of pie, the method of baking
the type of shelf. It is suggested that you attempt
experimental initial bakes at 600_F (316_C). Note
the time it takes to achieve a firm crust. If the
cheese breaks down too quickly or scorches eiĆ
ther lower your thermostat setting or top heat
switch setting. This will affect the length of your
baking time. If faster production is desired, atĆ
tempt additional bakes raising baking temperaĆ
tures in increments of 25 degrees or vary switch
settings on the upper and lower heaters. This will
help to determine the highest possible bake time
for achieving the desired results with maximum
production.
Baking time will vary depending on the number of
toppings on the pie. Generally, pies in pans should
bake in 5Ć8 minutes, pies on the shelf should bake
in 4:30 - 7:00 minutes.
Open doors as seldom as possible. hifting of pizĆ
zas is unnecessary in most cases.
The deck is intended for cooking pizza and bread
products, other types of food may be cooked in
pans or containers.
