Whenever working on any gas component like:
Gas valve, gas blower and / or changing connected type of gas, a detailed fl ue gas analysis
MUST be done using adequate CO and CO2 measuring equipment!
This shall ONLY be done by trained technicians!
Always check appliance for possible gas leakages!
Danger:
Changing the gas type of your SelfCooking Center or Combi Master
shall only be done if you have a fl ue gas analyser at hand.
Changing the gas setting only by adjusting the CO2 screw
will result in an unsafe fl ue gas condition,
is dangerous to life and will damage the equipment.

Check Gas Type - Gas conversion : SCC Gas from 04 - 2004
Whenever working on any gas component like:
Gas valve, gas blower and / or changing connected type of gas, a detailed fl ue gas analysis
MUST be done using adequate CO and CO2 measuring equipment!
This shall ONLY be done by trained technicians!
Always check appliance for possible gas leakages!
Danger:
Changing the gas type of your SelfCooking Center or Combi Master shall
only be done if you have a fl ue gas analyser at hand.
Changing the gas setting only by adjusting the CO2 screw will result in an
unsafe fl ue gas condition and is dangerous to life
and will damage the equipment.
Select Basic Settings:
A) • Switch on unit
• Open control panel
• Set DIP switch 1 on PCB to „ON“ position
• Select „Basic Settings
B) At „Basic Settings“ select position „Gas type“
C) Press key and select with the central dial the new gas type
G20=Natural Gas H, G25=Natural Gas L, G30=3BP, G31=3P,
13A=Natural Gas Japan
D) Confi rm new gas setting by pressing
the „Store“ key.
E) Select 3-Basic settings for average CO2 length
setting.
Note: Setting this screw to the given length shall ONLY bring the unit into
working condition with the newly supplied gas.
This does NOT replace fl ue gas analysis or make the fl ue gas analysis obsolete!
F) Set the CO2 screw according the values of the display or according the table
„Values for burner adjustments“(! ! ! Set all CO2 screws ! ! !)
If the mm setting of CO2 screw is too high, turn CO2 screw fi rst 2 turns clockwise
and then to the requested length (Screw adjustment tolerance)
G) Switch unit OFF and ON again to store newly gas type setting!
H) To exit service program set DIP switch 1 to „OFF“ position
I) Perform a complete fl ue gas analysis at Max speed of each burner
at the „Function Test“ ,as well as a cross-check of CO2 at Min speed
of each burner at the „Function Test“
