Important warnings
This device as an appliance of the 3rd class is intended to be built into a kitchen block.
Oven output (Hs) 1,1 kW (Mn = 80 g/h, propane/butane)
Grill output (Hs) 1,6 kW (Mn = 115 g/h, propane/butane)
(It is ensured and technically impossible that the two burners be turned on at the same
time.)
In case the gas tap may be hardly turned or if it gets jammed, it should be either replaced or the
respective cone of valve should be detached from the valve, cleaned by benzine and lubricated
with special grease for taps, e.g. from the company Klüber, Munich, type „Staburgas No. 32“,
and attached back. This act should be carried out only by an expert in gas appliances.
Installation of the facility may be carried out only by expert workers with appropriate
certificate!
This facility should be installed and connected according to applicable conditions of installation
as EN 1949. Special care should be paid to determined measures regarding aeration.
Before connecting the oven, it is necessary to check whether the local conditions for connections
(type of gas and gas pressure) are identical with the setting of the appliance. The type of gas and
the gas pressure for this appliance are indicated on the instruction plate (or the product's name
plate).
Before being put into operation as well as after each 2 years, the parts conducting gas and
connected exhaustion of waste gases (gas exhaust pipe) should be checked by an expert
according to applicable standards, especially to European Standard EN 1949.
The user is responsible for ensuring the check. The expert performing the installation of the oven
shall notify him/her of the obligation of check in writing.
The appliance may only be used for the purposes of baking and grilling and under the conditions
specified below. It may be in no case used for other purposes than described in these operating
instructions (e.g. for heating etc.).
The use of the oven may lead to a generation of heat and moisture at the place of installation.
Take care of good aeration of the kitchen: natural aeration openings should be clear or, as the
case may be, it is necessary to provide for a mechanical venting device.
Intense and long-term using of the oven may require additional venting, e.g. opening of the
window or operating of a mechanical venting device on a higher performance level.
The pressure reduction (regulator) used between the gas cylinder and the oven should be of
output 1.5 kg/h:

ATTENTION: ACCORDING TO APPLICABLE STANDARDS, THE DEVICE SHOULD
BE INSTALLED BY AN EXPERT.
IMPORTANT: TO AVOID ANY POSSIBLE ACCIDENT, IT IS NECESSARY TO
INSTALL THE DEVICE ACCORDING TO THESE INSTRUCTIONS. LOSS OF
WARRANTY IS A CONSEQUENCE OF INEXPERT INSTALLATION
„ANY MODIFICATION TO THE APPLIANCE MAY BE DANGEROUS, AND IS
THEREFORE NOT PERMITTED !“
1. AERATION OF THE ROOM
Every room where one or more appliances are to be installed must have one or more openings
to allow the entry of fresh air. Above the appliance there have to be one or several openings in
order to assure the exhaust of combustion and renewal of fresh air.
These ventilation openings must comply with the requirements of EN 1646-1, EN 1949 and
EN 721.
These openings need to be checked from time to time. If necessary, the user should clean them
(e.g., in wintertime, snow or dirt should be removed from the exhaust output and the
combustion air input).
If the appliance is built-in, safety regulations must be observed, and particularly the European
standard EN 1949.
Outlets of waste gases may not be installed at entrance doors and below aeration openings.
When exhaust gases are discharged, the ascending position of all parts needs to be
checked.
2. CONNECTION OF THE OVEN TO THE GAS SUPPLY
The connection of gas to the oven may be carried out exclusively with gas-tight connections.
Tubes used to connect the oven should be of zinc-coated iron or copper. These pipes may be
used only with gas-tight connection. Having finished connection works, it is necessary to
check tightness of the connection, using soap solution that is poured on the connection. Soap
solution shows possible leakages by creating bubbles.
ATTENTION: WHEN INSTALLING AND CONNECTING THE DEVICE, THE GAS
PIPELINE MAY NOT BE TWISTED, PULLED, NOR OTHERWISEE STRAINED.

3. GAS CYLINDERS
It is necessary to use such gas cylinders that are usually sold in the country of sale of the
appliance. Kind of gas used is clearly indicated on the packaging and on an indelible type
plate on the rear side of the oven.
UNSUITABLE OPERATION CONDITIONS OF THE FACILITY MAY BE A
CONSEQUENCE OF USING ANOTHER PRESSURE OR GAS THAN STATED IN
THE INSTRUCTIONS. THEREFORE THE MANUFACTURER DECLINES ANY
LIABILITY IN CONNECTION WITH INEXPERT OPERATION OF THE
APPLIANCE.
In any case, the following instructions shall be adhered to:
Complete gas cylinders with a valve and pressure reduction (regulator) should be placed in
vertical position in a cabinet exclusively intended for that purpose. Access to cylinders must
not be obstructed.
Replacement of gas cylinder should be simple, while it should be possible to carry it out
without any obstacles.
BE SURE TO SHUT THE GAS CYLINDER VALVE AFTER USE.
ATTENTION!
The following safety precautions should be adhered to, when replacing the gas cylinder:
a) close taps of the device (revolving button in the position „0)“;
b) shut the gas tap in the vehicle that is assigned to the appliance.
c) make sure there were no open flames or glowing objects around;
d) close the valve of the cylinder being replaced;
e) detach the pressure reduction (regulator) of the empty gas cylinder, take the gas
cylinder out of the cabinet and replace it with a new one –carry out connection of the
new cylinder in the reverse sequence.
f) dheck tightness, using soap solution, as explained above.
g) Ignite the burner and check whether the oven works properly. If it does not, contact a
specialised engineer.
3.1 CABINET FOR GAS CYLINDERS
A cabinet for gas cylinders should be sufficiently large to accommodate the shown type of
gas cylinder with pressure regulator attached. In Germany, its width and depth may not be
smaller than 325 mm and the height less than 620 mm.

4. VISUAL INSPECTION OF FLAME
a) The flame should burn quietly. It should be prevailingly blue, having clear outlines.
b) When the flame is not burning cleanly, there should be checked, whether openings of air
inlet (Venturi tube) are clear. If it is not the case, particles causing obstruction should be
removed.
c) In case of any doubt a gas specialist needs to be consulted.
5. POWER SUPPLY AND ELECTRICAL CONNECTION:
The appliance needs 12 V DC power supply for possible future internal lighting and
electronic stroke spark ignition. For special "Z" models, the stroke spark ignition will be
initiated by a replaceable 1,5 V battery.
ELECTRICAL CONNECTION
To connect the facility, a twin cable of 1.5 mm2with red and black colours should be used,
which shall be connected to the terminal placed on the rear side of the device. The poles on
this terminal are indicated + and –. You will recognise the positive pole by red colour. When
connecting the cable, in any case take care of correct poling! Electrical circuit should be fused
with 3 A safety fuse (not delivered with the device).
IN NO CASE THE DEVICE MAY BE CONNECTED TO 230 V MAINS SUPPLY!
THIS WOULD LEAD TO DEFINITE DESTRUCTION OF ELECTRIC PARTS AND
IT WOULD BE ASSOCIATED WITH A HAZARD TO THE CUSTOMER.
6. LEAKAGE OF GAS
When testing leakages of gas, we recommend you to use an electronic gas leak detector with
type approval. In case of a defect, the tap of gas supply must be closed. Contact a gas fitter,
dealer or specialised engineer.
