Installing the gas
1.
Compare the type of gas, the gas pressure and the rating 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.
'Data for gas operation' in 'Technical data'
on page 74
2.
Connect to the gas supply.
3.
Make sure that all the connections outside the appliance are gastight.
4.
Find out about the construction and position of the burner, and the lay-
out of its parts.
Positions of the fan burners and gas distri-
bution system on page 51
5.
Switch on the appliance.
6.
Make sure that all the connections outside and inside the appliance are
gastight. Seal any connections that are not gastight.
7.
Start a cooking profile in the Convection operating mode.
8.
Measure the supply flow pressure at the gas valve.
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 installation.

9.
Measure the CO values for the burner.
The appliance must not be put into use unless it complies with the
specified limits.
