Introduction
TRENDY PIZZA is a completely new developed pizza oven from Sveba-Dahlen. The oven design is compact, sturdy
and excellent for the busy rush hours. Trendy Pizza has a big capacity on a small foot print and is provided with a
unique, new developed computer panel especially designed for Sveba-Dahlen.
The computer panel will be programmed on site to a fuse size suitable for the facility. It means that the oven
automatically calculates how much current it can use and distributes it in an intelligent way to the two baking
chambers. The oven can thus be connected to a main fuse, which is lower than the total load of the oven. This
intelligent control then distributes the power to the two baking chambers following the pre-programmed principals.

Important
All correspondence must state: Type designation of oven
Manufacturing number
Supply voltage
It is essential for proper, safe operation of the oven that users are thoroughly familiar with its operation
and use.
Read these instructions before using the oven.
Unauthorized service or repairs may cause personal injury or damage to the equipment which may
invalidate warranty agreements.
Service and repairs to this equipment should only be entrusted to qualified engineers appointed by
SVEBA-DAHLEN.
Save this manual for later use.
Be cautious when moving oven on castors, as the centre of gravity is high and there is a great risk of falling
over at obstacles on the floor.
The oven must be connected via an external main switch with min. 3mm gap.
Exchange of the connection cable must be done by an authorized electrician.

Product description
Approval
The Trendy Pizza Oven is CE-approved in accordance
with the EMC- and the Low Voltage Directives.
Function
The oven has two baking chambers, whereof the lower deck is given priority by the panel. i e if, during low season,
only one baking chamber is used, we recommend you to use only the lower one and switch off the upper one.
If the main fuse in the facilities is not sufficient for the total load of the oven (32A), the computer panel will first-
hand distribute as much power as needed to the lower deck. Second-hand the power will be distributed to the upper
deck (25A min).
Now supposing that there is only one 25A main fuse in the facilities. When the oven is started up the lower deck will
get full power and then also the shortest heating-up time. The upper deck will get the ‘surplus power’ and
consequently the longer heating-up time.
When both the baking chambers have reached the set temperatures, the intelligent computer panel will distribute the
power to both the baking chambers in such a way that the ‘missing’ power will not be noticed.
Some power suppliers debit high penalty charges for subscribers exceeding the consumption agreed upon. For these
customers the controlling of the Trendy Pizza is the perfect solution, as it is possible to programme the oven to
consume only a certain amount of power.
The functions of the computer panel and how to use them will be described further on in this manual.
Oven design
The oven consists of two parts, one oven section and one
stand fixed to the bottom of the oven with four (4)
screws.
First start of the oven
NB. After the first start-up or after a power failure the E4 in the display will flash.
This indicates that the timer in the panel must be set (nothing wrong with the oven) See ”Setting of timer”

8Operating Maintenance Installation Trendy Pizza 4:3543-2 --> 860045-02
Ventilation
Make sure that the ventilation holes around the oven are
not covered. If the oven is to be built-in to a wall, this area
must be well aired not to damage the electrical parts. The
ambient temperature of the oven must not exceed 50°C.
When building-in make sure, that the distance between
the oven and combustible parts is at least 50 mm.
Electrical connection
The oven has to be connected with the cable (2,5 m)
delivered.
The earth potential equalizer screw has to be installed.
Earth potential Equalizer screw
Heating
The oven has a built-in quick-start-function (Turbo) that
guarantees that the set temperature will be reached as
quickly as ever possible. The function is switched on/
switched off automatically when need be.
At full electrical load the oven will reach 320°C in only
20 minutes.
Fuses
The oven is provided with built-in circuit breakers fixed
inside the panel door, easily accessible. When overheated
the circuit breaker is released through the overheat
protection of the oven (see under trouble shooting).
Circuit breakers
Evacuation
The Trendy Pizza oven is designed to be connected to an
exhaust pipe with mechanical ventilation. The oven is
prepared to be connected to a ø125 mm exhaust pipe.
Appropriate exhaust volume is 200-250 m3/hour. The
temperature of the evacuated air is approximately 40-
45°C.
If the oven is connected to a natural exhaust, there will
be no efficient evacuation of fumes and smoke from the
oven chamber by the canopy.

Description of AC guard (current delimiter)
The oven calculates the present power consumption.
”The maximum allowed current” is set in the service menu (see under Setting of service parameters). The power
consumption is not allowed to exceed this value. If one deck is disconnected because of a too high power
consumption, the temperature symbol on the display flashes. In the service menu you select which of the oven
chambers is to be given priority, when the power consumption is too high. From factory the lower oven chamber has
been given priority. When the power consumption no longer is needed, the panel will automatically disconnect this
function and the temperature symbol will stop flashing.
Built-in current delimiter
Description of turbo function
The oven is fitted with an automatic turbo function. If the difference between and pre-set and real temperature is
larger than a value set in the service menu, all heating elements will be given full power to quickly regain the correct
working temperature.

Baking tips
The oven is fitted with strong heating elements positioned
over and under the stone soles.
The position of these elements is thoroughly tested to
give a perfect baking, irrespective of where the pizzas
are being put in the oven.
Abundant heat from the upper heating elements is a must
to get a well baked pizza. Normal baking temperature is
about 320°C
Start setting the top heat on 8. Proceed by testing a setting
that suits just your pizzas. To start with set the bottom
heat on 1-2.
The front heat is intended to adjust the baking at the very
front door. If on this setting the pizzas are pale – increase
the front heat somewhat. A recommended start value for
the front heat would be 8-9.
The heat radiation from the upper heating elements will
heat the surface of the stone soles.
By longer interruptions in the baking the heat in the stone
soles will be accumulated. Therefore the first pizza
baked after such an interruption may have a somewhat
darker bottom. This ‘darkness’ will diminish the next
time a pizza will be placed on the same place in the oven.
If the full capacity of the oven will not be used, we
recommend that the pizzas are alternately placed in the
oven. This procedure will balance the temperature in the
soles and give a more even baking of the bottom of the
pizza.
By longer interruptions in the baking the upper heat can
be reduced somewhat. At rush hours the top- and bottom
heat can be increased. The el load of the ovens is amply
sufficient and consequently the oven quickly reaches
full power again.

Recipe
Recipe: 1850g Flour
35g Salt
20g Yeast (fresh)
40g Olive oil
1000g Water
Dough temperature should be 25° C (in order to make the bread extra tasty add 100 g of rye flour to the above recipe).
The recipe is calculated to approximate 12 pizzas.
Mix the ingredients with a dough mixer slowly for 2 minutes and fast for 4-5 minutes.
Let the dough rest for 2 hours.
Part it in pieces of 250 g each.
Cover it with plastic foil and let it rest in a cool place at 5-7° C for another 24 hours (the dough can be kept like that
for about a week).
Form round plates of 30-35 cm in diameter. Cover them with tomato sauce, grated cheese and shredded ham. Bake
them in the Trendy Pizzaoven at 320° C with upper heat 8, lower heat 2-4 and front heat 9 for 3,5-4,5 minutes. Put
some olive oil at the edges and sprinkle with some oregano.
This is an original pizza, but you can put anything you like on it.
Enjoy your meal!
