Before you carry out a fl ue gas analysis
check input gas fl ow pressure when burner is running
• Switch on unit. Select any mode and cooking time.
Wait till burner works
• Check input gas fl ow pressure
• See correct values of input fl ow pressure on serial plate
• If necessary adjust gas input pressure
Select „Function Test“:
• Switch on unit
• Open front panel
• Set DIP switch 1 on PCB to „ON“ position
• Select „Function Test“
Select at „FunctionTest“ the position „Gas Steam Burner“
Press key and select „Max“ rpm,
if it‘s not already selected

Display 4 indicates the desired CO
2
value, e.g. 9,2%,
fl ame current, i.e. 5,2μA and the corresponding rpm of the
blower motor.
Place fl ue gas testing nozzle in correct fl ue outlet
„Adjust CO
2
to given value by turning CO
2
screw on gas valve.
You also can fi nd that value on table „Values for burner adjus-
tments“
• If CO
2
value is too low => turn CO
2
screw
anti clockwise (+ direction),
• If CO
2
value is too high => turn CO
2
screw
fi rst 2 turns clockwise (- direction), and than slowly
anti clockwise (+ direction) until you get the indicated CO
2
value. (Screw adjustment tolerance).
• CO value must be below 300ppm
Press „Stop“ key. Blower will stop.
