GAS CONVERSION INSTRUCTIONS
This conversion kit allows you to convert the gas hob from natural gas (G25 / 25 mbar) to propane/butane gas (G30 / 28-30
mbar) or natural gas (G20 / 20 mbar). Before beginning the conversion, make sure your gas hob is actually set for natural gas.
Attention:
The execution of this instruction by an unauthorized mechanic can lead to dangerous situations.
Inventum can not be held liable for any damage (causing a hazardous situation and / or damage to persons and property)
resulting from failure to follow the safety instructions and warnings by a specialized technician. Damage caused by incorrect
execution of these instructions is not covered by the warranty.
This conversion kit consists of original parts. Original parts are being approved on suitabilty and safety during the approval of
the device. Regular examinations guarantee the quality of the original parts.
Inventum recommends to have a specialized technician carry out the conversion of a device to a different type of gas.
Tools
•
Leak spray and/or special pressure gauge
•
Tube- or socket spanner 7
•
Screwdriver 2 mm (blade width)
Attention:
Test the gas density after converting the gas hob.
Replace the following parts:
•
injectors for the burners
DISASSEMBLE
Prevent damage to the work top.
Place parts of the appliance on a protective surface.
1.
Remove the pan supports, the burner caps and the burners.
2. Remove the injectors from all the burners. Use a tube- or socket spanner 7.
3. Pull the control knobs straight up and remove them.
CONVERTING
1. Insert the new injectors in the burners. Again use a tube- or socket spanner 7.
For verification, you can find the values of the injectors, in the gas table of values for
injectors on page 25.
2. Place the burners and connect the gas hob.
3. Adjust the simmer setting with the simmer setting screw, using a small screwdriver.
The simmer setting screw can be found in the valve housing of the gas tap. When
the simmer setting screw is on the body of the gas tap, the screw can be reached
through the gas tap cut-out in the drip tray. The drip tray does not need to be
removed. Ignite the burner, turn the gas tap to simmer setting and adjust the
flames to a length of approx. 4 mm.
Please note:
the flame must not blow out in simmer setting. After adjusting, the
flame should burn stable. That is to say that the burner may not blow out when
fanned manually.
4. Stick the enclosed data label partially on the current data label to the bottom of the
gas hob, covering the current gas data.
Warning!
Check the injectors on gas density. Always check the gas density before using the appliance!
CHECKING FOR GAS DENSITY
Checking for gas density with the aid of a leak spray when the appliance is connected to the gas supply:
1. Seal the injector.
2. Open the gas supply.
Attention;
valves with a thermo electric safety must be pressed, turned open and kept pressed!
3. Spray leak spray around the injector inside the burner and check it for gas density.
Check for gas density with a pressure pump when the appliance is
not
connected to a gas supply:
1. Connect the pressure pump to the gas pipe and close all gas taps.
2. Increase the pressure up to 150 mbar and close the tap between the pressure pump and the pressure gauge. Check the
pressure. The pressure loss may amount to a maximum of 5 mbar per minute. After checking, open the tap between
the pressure pump and the pressure gauge.
3. Open one of the gas taps and close the corresponding injector.
Attention;
valves with a thermo electric safety must be pressed, turned open and kept pressed!
4. Increase the pressure up to 150 mbar and again close the tap between the pressure pump and the pressure gauge.
Check the pressure. The pressure loss may amount to a maximum of 5 mbar per minute.
5. Repeat this check for all the gas taps and injectors.
