The Biological Oven is a product innovation aimed at making your life easier by helping you
nourish yourself perfectly on healthy food. While the traditional attitude towards the wholesome
cuisine is that it is time-consuming, the new Biological Oven will manage it that simply. Prepare
your dishes to the minute at low temperatures, at the same time preserving all essential vitamins
and nutrients while economising on time and energy.
Of course you may also utilise the Biological Oven as a conventional oven, availing yourself of all
functions that go with it, such as combined top/bottom heat, only top heat, only bottom heat plus
grill setting.
We are pleased you decided in favour of this multi-purpose and state-of-the-art appliance and
thank you for your confidence. Its easy operation and wide range of application are bound to
captivate you, too. To make sure you can enjoy using this appliance for a long time, please read

What Low Temperature Cooking and Gentle Cooking involves
Professional chefs swear by the ‘Gentle Cooking’method involving low temperatures. Meat turns
out extraordinarily juicy, whereas cooking losses are reduced by up to 60%. While Low
Temperature Cooking is being performed at cooking temperatures from 60°C –100°C, the Gentle
Cooking method presupposes cooking temperatures from 100°C - 150°C. The cooking time is
longer than that required for conventional cooking. However, as preparations in the new Biological
Oven are fully automated, you will economise on time, indeed. And: The cooking time may be
extended after your fancy, for meat will stay tender and juicy even if kept in the oven for a longer
amount of time.
In the Low Temperature Cooking mode you may prepare any kind of quality meat and fish fillets.
It can be particularly recommended to cook pieces of sirloin of pork, beef, venison and lamb, while
you will also achieve excellent results for meat loafs, stuffed pepper bell peppers and stuffed
cabbage. What greatly matters is that you choose well-hung meat of young animals.
3. Initial use
For a start, remove all transport wrappings and packaging materials as well as the protective film
on the partition plate. Then clean all accessory parts in warm water, mixed with a little
dishwashing detergent. Doing so, make sure not to immerse the meat probe in the water, but just
wipe with a damp cloth.
Prior to first usage, the protective coating of the heating elements has to be burnt in.
To this end, please heat the appliance, without the meat probe, for approx. 20 minutes on
maximum heat setting by choosing "top/bottom heat" first and then the “grill”setting (refer to
sections 5 - “Setting the Time and the audible signal’s sound level”and 6 - “Manual Operation”).
Please do not be bothered by the faint temporary formation of smoke, which is absolutely
harmless.
After the appliance has cooled, please clean the oven chamber with a damp cloth. Prior to each
usage, check that the oven is dry.
4. How to use the appliance
All functions of the BGO 1600/E are controlled via a digital clock timer and via the connected meat
probe respectively.

The functions of bottom heat, combined top/bottom and grill (however presupposing a suggested
temperature of 280°C) are identical with the above described top heat function.
By contrast, the combined top/bottom heat function with meat probe differs from the other set of
functions in so far as this function does not allow for any operating time to be set. This function is
only limited by the switch-off temperature around the meat probe being reached. The point in time
when the preset value is reached is above all dependent on the type, size and quality of the food
to be roasted or baked.

This will prompt deactivation of any heating functions and interruption of any operating times
probably effective. Interruption is signalled by the oven symbol in the upper right-hand corner of
the display extinguishing. Depending on the respective programme step, the temperature currently
prevailing around the meat probe and the operating time effectively remaining will be indicated.
Briefly re-pressing the Start/Stop Button [►■] will make the function resume. Any manual function
that is stopped will be automatically quit after 12 seconds unless a button is pressed. Thereafter,
the current time will be indicated again.
6.6 Finish of operating time / Core temperature reached in Manual Operation
If a time was preset for a manual function, you will hear an intermittent signal for approx.
1 minute once the pre-programmed time has elapsed. At the same time, the appliance will power
down automatically. The oven symbol in the upper right-hand corner of the display will extinguish
and the remaining operating time will be indicated as “0”min.
Likewise, you will hear an intermittent signal when the preset core temperature was reached in the
“combined top/bottom heat with meat probe”function. In that case, too, the oven symbol in the
upper right-hand corner of the display will extinguish, whereas the current core temperature will
continue being activated on the display.
The audible signal may be acknowledged by pressing any button. Thereafter, the current time will
be indicated again.

7. Automatic Operation
In Automatic Operation, a fixed sequence of functions is executed successively. You can choose
between two programme modes in Automatic Operation:
Gentle Cooking/Low Temperature Cooking
(involving 2 programme steps:
start time; combined top/bottom heat until
core temperature is reached). This
programme mode presupposes the non-subdivided oven chamber.
Menu Cooking
(with 4 programme steps: start time; top heat until core
temperature is reached; bottom heat for preset operating time, rest period
(pausing) for preset rest period).
This programme mode presupposes the subdivided
oven chamber requiring the stainless steel partition plate as included in the delivery
scope. In the lower part of the oven chamber you may simultaneously cook the side
dishes that go with the menu, such as vegetables and potatoes.
Programmes P1-P12, as described in the table below, have been tested in the settings mentioned
and are firmly pre-programmed. Programmes P1-P8 relate to Gentle Cooking and Low
Temperature Cooking; P9-P12 relate to Menu Cooking. Furthermore, there are 8 (P 13-20) vacant
programmes available.

Notes:
- If you prefer your poultry or meat to turn out crispy brown, remove the meat probe after
the cooking process and allow the meat to grill for about 5-10 minutes in the same oven
(opting for the “Gr”function)
- Older meat lacking an adequate degree of maturation (concerns beef, especially) may
prevent the meat from becoming sufficiently tender by the approximate times indicated.
Therefore, it is recommended to keep such meat simmering in the gravy for an extended
amount of time.
- During menu-based gentle cooking of vegetables, fill the steamer insert with 1/4 l of cold
water and place on the right side of the lower half of the oven chamber. In order to
accomplish simultaneous cooking with the vegetables, quarter large potatoes and
submerge by 2/3 in salted water. Thereafter, place the container on the left side of the
lower half of the oven chamber.
- Dealing with the subject of Low Temperature Cooking there is available comprehensive
literature as well as special cookbooks, providing lots of further information and ideas.
7.1 Starting time
All programmes allow for programming the start for later. The start time refers to the time at
which the programme starts. The start time setting is indicated by the “bell”symbol. The start
time allows you to place all food in the oven beforehand, while postponing the programme start to
a later time. The start time can be set within a range from “current time”to “current time
+23:59h”. With a Menu Cooking programme it is thus possible for a complete menu to be
prepared even while you are away.
Example of how to avail yourself of the start time facility:
Cooking 400g of tenderloin of pork (opting for programme P 10) will require you, depending on
the quality of the meat, to let it roast for about 2 hours until the core temperature of 55°C is
reached. An additional 25 minutes will be needed to cook the side dishes (such as vegetables and
potatoes) as well as 10 minutes of rest period, resulting in an overall time of about 2 hours and 35
minutes for Menu Cooking. All prepared ingredients are placed in the oven at 8:30 h already. By
pre-programming the start time, the programme start subject to P10 is set to 9:55 h. The
programme will only start to run at the pre-programmed time. Therefore, the complete menu will
be ready at about 12:30. Within the period of 9:55 h to 12:30 h, the entire cooking process is
proceeding automatically.
For recommended cooking times relating to the varying quantities of meat and temperature
settings, please consult the tables in the appendix.
7.2 Selecting and starting a programme
When the current time is indicated, you can change to the programme menu by pressing the
Programme Button [P]. The programme menu can be prompted by pressing the Programme
Button [P] repeatedly or by pressing the Plus [+] and Minus [-] buttons. The menu always starts
with the programme last used.
Fig.: Selected programme P5
Thereafter, the selected programme can be started directly, subject to the stored temperature and
time values, by pressing the Start/Stop Button [►■]. The meat probe must be connected
in all Automatic Operation programmes.
However, when required, you may also choose to set the temperature and time values ahead of
programme start. After the start the programme will proceed subject to the altered values only
once, while they cannot be stored permanently. When the programme is activated for the next
time, all the pre-programmed standard values will be active again. By contrast, programmes P14-
P20 are freely adjustable and storable.

9
7.3 Setting temperature/time values with programmes P1 –P12
After selecting a programme, you may set the belonging temperature and time values by pressing
the Setting Button [°C]. The values on the display may be varied via Plus [+] or Minus [-].
Depending on the type of menu (type of programme), you may choose between different
temperature and time values. During the setting procedure the automatic symbol “A”in the upper
left-hand corner will not glow. The symbol on the 4th digit is a static one (difference to Manual
Operation: 4th digit is blinking during the setting process).
General notes
- Temperatures can basically be set within a range from 50-300°C.
Setting the temperature to 0°C will skip the relevant programme step.
- The switch-off temperature for the meat probe can be adjusted within a range from 10°C -
99°C. If the switch-off temperature is set to 0°C, this programme section will be skipped.
- The duration of a programme step can be defined within a range from 1-99 min.
If the duration is fixed as 0 min., the relevant programme section will be skipped.
- The start time can be set within the range from “current time”to “current time + 23:59h”
- If no button is pressed for more than 12 seconds, the menu will be quit automatically.
Thereafter, the current time will be indicated again. The values set until then will be quit.
- You may start the programmes during any setting step, subject to the parameters currently
set, by pressing the Start/Stop Button [►■].
