3 Instructions on Safe-handling of the Equipment
3.1 General instructions
The equipment is a technical appliance that is only intended for commercial use.
The gas ranges are used for the commercial preparation of meals in the containers provided for this
purpose such as pots and pans. Regulations applying to commercial kitchens are to be observed.
The appliance is not suitable for spatial heating nor for the warming up of other materials – except those
normally used in cooking.
The temperatures necessary for cooking processes inevitably mean that various top surfaces and panel
parts can become very hot. This is not a design defect. It is simply a physical fact.
Ventilation of the work rooms complying with the regulations is to be ensured.
Technical modifications to the equipment by unauthorised persons without written permission from the
manufacturer completely nullify any claims under the guarantee and invalidate any claims in respect of
product liability.
These instructions are to be made known to the members of staff affected in the context of an operating
directive.
3.2 Safety instructions for operating, cleaning and repair
The operating and cleaning may only be carried out by personnel who have received appropriate
instruction. Maintenance and repair may only be performed by qualified specialists who have received
training.
The manufacturer cannot be made liable for damage due to inexpert connection and handling. Claims
made under the guarantee in such cases are also invalid.
The appliance is only to be operated under supervision. It may only be operated in an adequately
ventilated room.
Do not set up the equipment next to walls, kitchen furniture, and decorations or similar which are made of
flammable materials. Otherwise there is danger of fire. See connection diagram with equipment
description for minimum distance. Local fire protection regulations must be kept to absolutely!
Several parts such as gas extraction duct, oven door, the top plate, of the range are, by their nature, very
hot due to the high temperatures needed for cooking. Protect yourself by only touching the control
elements provided and by wearing clothing that prevents direct skin contact.
Gas appliance safety:
All subsequent constructional modifications to rooms housing the appliances that impair the adequate
supply of combustion air to the gas appliances are not permitted as these not only affect the correct
functioning of the appliances but can also have fatal consequences for those working there.
If there is a smell of gas, do not light a flame! Immediately close the gas supply valve on the customer
side! Open windows, carefully check whether there is a leak. If the cause cannot be identified or
remedied, immediately inform a gas installation firm or the gas supply utility!

If the appliance is to be shut down: First put all gas valves to "Off" and then close the gas supply valve
within the customer's extent of supply. This applies also in the case of repair work.
Appliance with gas-fired roasting and baking oven
It must be checked and made sure that the flue gas path of the oven is not obstructed by foreign bodies
or constricted in any way. Only operate the oven with the door closed.
Appliance with electric roasting and baking oven
Before repair work is started, the equipment must be disconnected on all poles from the power (using
isolating equipment in the customer's supply, e. g. fuses).
3.3 Instructions for transport
Transport ascobloc equipment only in the original packaging. This avoids unnecessary damage and
expense.
Check equipment for damage.
Do not lift or shift the appliance by holding the top plate, the bottom edges at the sides of the appliance or
by the door handles. The bottom edges at the front and rear of the appliance are provided for this.
4 Installation
The manufacturer cannot be made liable for damage due to inexpert transport and installation. Claims
made under the guarantee in such cases are also invalid.
Gas transporting elements and electrically live components may only be installed, replaced or modified by
authorised specialist staff.
The appliance must be set up in a well-ventilated room, if possible under an extraction hood (see DVGW
Worksheet G 634).
The technical data for electricity and gas are to be found on the type plate on the front panel (A) (see data
sheet).
4.1 Setting up
Do not set up the equipment next to walls, kitchen furniture, and decorations or similar which are made of
flammable materials. Otherwise there is danger of fire. See connection diagram with equipment
description for minimum distance. Local fire protection regulations must be kept to absolutely!
It is of importance that the equipment be set up absolutely horizontal (use spirit level for alignment) so
that the doors can be opened and closed without any problem and that they seal tightly when closed.
Equipment with adjustable feet can easily compensate for unevenness in the floor (+/- 20 mm) by turning
the bottom ends of the feet. If set up on a plinth, this is to have an underlay if needed.
4.1.1 Free-standing set-up
If the equipment is to be set up on its own, suitable means are to be used to protect it against tilting and
shifting.
4.1.2 Setting them up in groups or blocks
When setting up in groups or blocks, the equipment must be joined together by connecting elements
provided for this purpose. This is for the sake of hygiene. Observe equipment setting up sheets or
assembly diagram (data sheet in annex).
4.2 Connections
Details of connections for the media can be taken from the accompanying connection diagram and
equipment description. Check whether the size and position of the electrical connections of the customer
side correspond to the information in the connection plan, equipment description or installation plan
The terminal box for the connections is located behind the front panel A (see data sheet). Make the
connections as shown in the annex or in the connection diagram accompanying the equipment. The
number of the connection diagram is to be found on the type plate. Once the electrical connections have
been made, close the cover of the terminal box and screw the front panel in place again
The connections can be made from below or from the rear from a closed installation space. With the
connection from below, the pipe length must be 50 mm above the floor surface.
You can get the necessary technical data about the type of gas and its pressure from your gas supply
utility.
4.2.1 Gas type, connection pressure
The appliance is set up in the factory for the type and category of gas noted on the type plate of the
appliance. The type of gas and the supply pressure must match the gas setting given on the appliance. If
not, a conversion or adaptation of the appliance must be made to suit the local conditions (see
conversion instructions).

4.2.2 Extraction of flue gas
Gas ranges are of Type "A", i.e. the connection of a flue gas system is not required.
Ventilation of the rooms where the appliances are set up has to comply with the regulatory guidelines in
the DVGW Worksheet G 634.
Appliance with gas-fired roasting and baking oven
The flue gas duct supplied is firmly fixed to the flue gas duct of the oven using the screws supplied. The
slant of the flue gas duct must point to the operating side of the appliance.
Connection location
The connection compartment is accessed from the front. It is located behind the front panel A (see
connection diagram). Once the connection has been made, screw the front panel back in place.
5 Proper Use of the Equipment
5.1 Operational start-up
•Remove the protective film before bringing into operation.
•Clean the equipment with dilute soap solution.
5.2 Functional test
5.2.1 Gas range
•Check that the burner cover is correctly seated.
•Check the supply pressure (flow pressure): Connect the pressure gauge to the pressure measuring
nipple of the main gas pipe.
•Bring the burners into operation and check whether the allowable supply pressure is maintained.
•Check whether the nozzles appropriate to the gas supply have been installed (see conversion
instructions). Close the sealing screw of the pressure measuring nipple again once the measuring is
finished!
•Bring all burners into operation. There is air in the lines prior to the first ignition so it takes somewhat
longer till the pilot flames can be ignited.
•Check for ignition from the pilot to the main burner, through-ignition and a regular flame pattern.
5.2.2 Appliance with gas-fired roasting and baking oven
•Inspect the flue gas duct of the oven.
•Check the switching function of the oven's temperature controller.
5.2.3 Appliance with electric roasting and baking oven
•Bring upper and lower heat separately into operation. The green indicator light for operational readiness
must light up.
•Set the knob for the top and/or bottom heat to 50°C. The yellow indicator light must light up. The yellow
indicator light goes out after a short time when the temperature set for the roast/baking oven is reached.
5.3 Operating
5.3.1 Gas cooking zones (see Figure 3)
Open the gas supply valve within the customer's supply before commissioning. Turn the cooking zone
control knob to "Star" and keep it pressed in. Ignite the pilot flame using the igniter and hold the knob in
the pressed-in position for about 10 seconds.
Parboiling at high power with a "large flame", simmering on a "small flame". The setting needed for
simmering depends on the condition of the cooking utensils and the quantity of food to be cooked.
With the knob at the "Star" position, the cooking zone burner is held in readiness; only the pilot flame is
on. Knob at the "Zero" position extinguishes the burner and the pilot flame of the cooking zone. If the
appliance is to be taken out of operation, first set all knobs to "Zero" and then close the gas supply valve
within the customer's supply.
5.3.2 Baking oven (optional)
Electric roasting and baking oven
•If the oven has convection heating as an extra, the changeover switch (6) must be in mode (II)
•The temperature is set by turning the knob (temperature controller),
•separately for top heat (2) and bottom heat (3)
•When the oven is switched on, the green or the yellow light is on
•When the preselected temperature is reached, the yellow light goes out
Electric convection oven:
•Set the changeover switch (6) to convection (I)
•The temperature is set by turning the knob (2) for top heat
•When the oven is switched on, the green or the yellow light is on
•When the preselected temperature is reached, the yellow light goes out
•The temperature in convection mode is limited to a maximum of 250°C.

•Always pre-heat to get the best results when roasting and baking.
Refer to the data sheet for the numbers
The rocker arm on the oven door can be used to reduce the moisture level in the oven
Attention: In convection mode, heating and fan remain in operation, even when the door is open!
Gas-fired roasting and baking oven:
•Open the gas supply valve within the customer's supply before commissioning. Turn the oven control
knob to "Star" and keep it pressed in. Light the pilot flame with a gas igniter underneath the igniter flap
in the floor of the oven and hold the oven control knob in the pressed-in position for a further 10
seconds.
•With the oven knob at the "Star" position, the cooking zone is held in readiness; only the pilot flame is
on. Knob at the "Zero" position extinguishes the burner and the pilot flame.
•Always preheat the gas-fired roasting and baking oven before use. The gas-fired oven is
thermostatically controlled. You can make use of the various levels in the oven. Only use one insertion
level at any one time
Reduce considerably the heat to the cooking zones and oven when they are not occupied; this avoids
unnecessarily high temperatures in the appliance and the surrounding air and reduces unnecessarily high
energy consumption. Very high temperatures during idle periods lead to excessive wear and a shortening
of the service life of thermally loaded components.
5.4 Cleaning
5.4.1 Top plate of the range
The pot grid supports can be removed to make cleaning of the top plate easier. Do not clean the pot
supports with soap-steel-wool pads (e. g. AKO pads, Abbrazzo) or other cleaning aids that scratch.
The burner covers can also be removed. Never clean the burner covers in the dishwasher (affects the
function!).
When cleaning the top plate, care must be taken that no dirt or water can get into the burners. To do this,
cover the main burner and the pilot flame tightly with aluminium foil. The cover of the pilot flame can be
removed if there is heavier soiling. A discolouration of the pilot flame cover due to the temperature of the
pilot flame is possible but does not impair its function.
Do not flood the top plate – wipe it out with cloths.
5.4.2 Roasting and baking oven
To avoid interruptions in operation and for hygiene reasons, the appliance should be cleaned daily after
use. The seats at the sides for the containers can be disengaged, taken out and cleaned in the
dishwasher. The oven floor can also be removed.
Spray grids and surfaces of the oven with commercially available stainless steel cleaner or oven cleaner1,
close the oven door and leave for 10 to 20 minutes to take effect. Then clean with a coarse sponge and
wipe out with clear water. After the cleaning, leave the oven door open for ventilation of the oven.
1ATTENTION! The cleaning agent to be used must be free of chlorine and fluorine compounds as these
halides can attack even high-quality stainless steel.
6 Repair and Maintenance
6.1 Repair and Maintenance
Please also observe the cleaning and care instructions in the annex!
If there are any signs that functioning is impaired even in the slightest or there are other defects, e. g.
traces of rust, changes in flame pattern, changes in operating behaviour or unusual odours, a
maintenance or service is necessary.
6.2 Measures to be taken for a longer outage in operation
If the appliance is taken out of service, the first step is to close all gas valves on the appliance and then
close the gas supply valve in the customer's extent of supply.
Clean the appliance thoroughly. Dry out the oven completely before the doors are closed.
Disconnect the appliance from the gas supply and from the mains.

9 Conversion to other types of gas
The appliance can be converted to use other types of gas. The conversion must be performed by an
authorised installing company and carried out in compliance with locally applicable regulations. To do
this, the appliance is to be completely disconnected from all electrical supplies and close the gas supply
valve in the customer's extent of supply.
The technical possibilities are listed in the "Nozzle Sets" table. Material can be ordered according to the
table from Customer Service or dealers. The use of nozzles other than those authorised for the
gas/supply correction pressure leads to destruction of the appliance and to health hazards for the
personnel (CO emission).
The gas adjustments carried out in the factory are given on the gas type plate. Subsequent conversions
to other gas types or supply pressures must be entered permanently and legibly on the gas type plate of
the appliance. Such labels are enclosed with replacement nozzle sets. Only use special nozzles obtained
from Customer Service or dealers!
9.1 Changing nozzles
The main and small adjustable nozzles of the cooking zone burners and of the small adjustable nozzles
in the gas-fired oven are accessible once the valve cover of the all-gas valve has been removed. First,
pull off all control knobs. Do this by inserting a flat-blade screwdriver behind the knob and at the same

time grip the knob at the back with two fingers. Then loosen the screws under the valve cover. Carefully
remove the valve cover. Avoid damaging the thermostat lines in appliances with oven!
9.2 Cooking zone burners
Refer to figure on conversion instructions for gas cooking zones.
The main nozzle (B) is located in front of the burner injector. Remove the grub screw at the side of the
injector and pull the nozzle holder with main nozzle out of the injector. Unscrew the main nozzle (SW 14)
from the nozzle holder and screw in the new nozzle till the end stop is reached.
The small adjustment nozzle (A) is screwed in on each all-gas valve at the top left. Unscrew small
adjustment nozzle (black O-ring) with flat-blade screwdriver and replace with new nozzle.
9.3 Pilot flame burners in the cooking zones
The pilot flame nozzle is changed from above. Remove the pot grid support and pull off the ignition
burner cap (C). Loosen the plug screw at the top SW 14 and unscrew the ignition burner nozzle using a
long box spanner SW 5.5 (with clamping ring, if possible).
9.4 Oven burners
(See figure in conversion instructions for gas range with gas-fired oven)
The main nozzle (F) of the oven burner is behind the lower front panel. Once the lower front panel has
been removed, unscrew the lock nut (D) on the nozzle holder, undo screw (E) and remove old main
nozzle (F). Assemble screw (E), new nozzle (F) and spring, and insert. Carefully turn the screw till the
end stop is reached and screw on the lock nut.
Change the small adjustment nozzle (green O-ring) in the same way as for the cooking zone burner.
The pilot flame nozzle (G) lies underneath the ignition burner. Unscrew the ignition gas line (H) from the
floor and pull lightly downwards. Change the ignition nozzle (G) at the end of the ignition gas line and
screw on again.
Once the conversion is completed, the appliance must be subjected to a complete test just as if it were an
initial commissioning!
