Leak-testing the cooktop
After the final gas connection has been made, turn the manual gas valve on and test the cooktop
and all connections in the gas supply piping for leaks with a soapy water solution. During leak-
testing, all the gas valves on the cooktop must be closed.
The presence of bubbles indicates a leak. If a leak is present, tighten or replace connections as
appropriate.
Important!
Do not use any naked flame to check for leaks.
Converting the cooktop to a different gas type
Important!
The conversion procedure must be carried out only by an authorized person.
This appliance is supplied with a set of injectors for the various types of gas.
Use the ‘Gas rate summary’ (following) to select the appropriate injector.
To convert from one gas type to another, you need to reset the gas pressure regulator, replace
the injectors, adjust the minimum burner setting, re-test for leaks and fill in/affix the gas
conversion labels.
1
Reset the gas pressure regulator:
Unscrew the regulator cover and remove it.
Unscrew component “A”, reverse it and screw it back in according to the gas type you are
converting to (see Fig. 14 below).
2
Replace the injectors:
Remove the grates, burners and the control knobs.
Using a wrench, replace the injectors with those suitable for the kind of gas you are
converting the cooktop to. See the ‘Gas rate summary’ (following).
Note: the burners are designed so that regulation of primary air is not required.
