Leak test and function test
:
Risk of explosion!
Avoid sparking. Do not use an open flame.
Perform the leak test only with a suitable leakage spray.
In the event of a gas leak
Shut off the gas supply.
Ensure that the room affected is well ventilated.
Check the gas and valve connections again. Repeat the leak
test.
The leak test must be performed by two people, in accordance
with the following instructions.
Check the gas connection
1.
Open the gas supply.
2.
Spray the gas connection with a leakage spray.
If small bubbles or foam form, indicating a gas leak, follow the
instructions in the section entitled "In the event of a gas leak" .
Checking the burner nozzles
1.
Open the gas supply.
Carry out the leak test separately for each nozzle.
2.
Carefully close the hole in the burner nozzle to be checked
using your finger or a suitable device.
3.
Spray the nozzle with a leakage spray.
4.
Press the function selector and turn it anti-clockwise. This
supplies the nozzle with gas.
If small bubbles or foam form, indicating a gas leak, follow the
instructions in the section entitled "In the event of a gas leak" .
Checking the bypass valves
1.
Open the gas supply.
Carry out the leak test separately for each bypass screw.
2.
Carefully close the hole in the burner nozzle to be checked
using your finger or a suitable device.
3.
Spray the nozzle in the burner to be checked with a leakage
spray.
4.
Push the control knob and turn it anti-clockwise. This supplies
the nozzle with gas.
If small bubbles or foam form, indicating a gas leak, follow the
instructions in the section entitled "In the event of a gas leak" .
Correct flame formation
Burner
The burning behaviour and soot formation must be checked for
each burner after the gas type has been changed.
If there is a problem, the nozzle values must be compared with
the values in the table.
1.
Ignite the gas burner in accordance with the instructions in
the operating instructions.
2.
Turn the control knob to the small flame setting.
Check whether the flame safety system is operating by
holding the flame at the "Small flame" setting for one minute.
3.
Check the correct burner behaviour for large and small
flames. The flame should burn evenly and constantly.
4.
Turn the control knob quickly from the large flame to the
small flame and back again. Repeat this process several
times. The gas flame must not flicker or go out.
