Converting to a different gas type
■ The gas connection must be replaced.
■ The nozzles for the burners must be replaced.
■ Depending on the factory gas setting, the bypass nozzles in
the burner valves must either be replaced, or screwed in fully.
Numbers are printed on the nozzles indicating their diameter.
Further information about the gas types suitable for the
appliance, as well as the corresponding gas nozzles, can be
found in the section entitled "Technical properties - gas".
After the conversion
■ After the appliance has been converted to a different gas
type, you must perform a leak test. See the section entitled
"Leak test".
■ After the appliance has been converted to a different gas
type, you must check the flame behaviour. See the section
entitled "Correct flame behaviour".
■ Enter the newly-set type of gas and gas pressure in the table.
See the section entitled "Measures to be observed".
Caution!
After the appliance has been converted to a different gas type,
the labels giving information on the gas type and showing a
star must be affixed at the appropriate point on the rating plate
MAKE SURE THAT YOU DO THIS.
Functional parts for the gas conversion
The functional parts that are required for the gas conversion in
accordance with the instructions are displayed below.
You will find the correct nozzle diameters in the table in the
section entitled "Technical properties - gas".
Always use new seals.
The gas connecting piece to be used may vary depending on
the gas type and country-specific regulations.
(*) These functional parts must be used when the gas is
connected.
Conversion from natural gas to liquid gas
(LPG)
If the appliance is to be converted from natural gas
(NG: G20, G25) to liquid gas (LPG: G30, G31):
If liquid gas (LPG) is used, the gas connection is established
via a gas hose or a fixed connection.
1. The natural gas adapter on the appliance must be replaced
with a gas connection hose. First remove the safety hose or
gas line, if present, from the appliance.
To do this, disconnect the threaded connection piece on the
gas line or the safety hose (with a size 24 key) from the
connecting piece on the appliance (with a size 24 key).
Figure 1.
Disconnect the connecting piece (with a size 24 key) from
the end of the gas connection (with a size 22 key). Figure 2.
2. Place the new seal on the connecting piece. Make sure that
the seal is correctly seated.
3. Attach the connecting piece (with a size 24 key) to the end of
the gas connection (with a size 22 key).
4. Insert the safety hose and tighten using a screw coupling or
hose clamp.
5. To perform a leak test, see the section entitled "Leak test".
Open the gas supply.
Note: A torque spanner should be used when converting the
gas type.
