Installing the gas

Compare the type of gas, the gas pressure and the rating
1.
for the gas supply connection with the data given on the
appliance type plate.
The appliance must not be connected to the gas supply or
put into use unless the values match those on the type
plate.
Connect to the gas supply.
2.
Make sure that all the connections outside the appliance
3.
are gastight.
Find out about the construction and position of the burner,
4.
and the layout of its parts.
Switch on the appliance.
5.
Make sure that all the connections outside and inside the

appliance are gastight. Seal any connections that are not
gastight.
Start a cooking profile in the Convection operating mode.
7.
Measure the supply flow pressure at the gas valve.
8.
Result:
If the supply flow pressure is higher than the specified
■
range, it may be possible to reduce the level.
If the supply flow pressure is lower than the specified
■
range, then you as gas fitter will not be able to correct
this.
If the measured value lies within the specified limits,
■
continue from step 9 of these instructions.
If you cannot manage to achieve a supply flow pressure
■
within the limits, shut off the gas supply to the combi
oven at the gas shut-off device and discontinue the in‐
stallation.
Measure the CO values for the burner.
