Measure the supply flow pressure at the gas valve.
Result:
■
If the supply flow pressure is higher than the specified range, it may be pos-
sible 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 dis-
continue the installation.

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

Switch off the appliance.
11.
Notify the following bodies (where necessary) of the installation that has been
made:
■
Gas provider
■
Relevant authorities in accordance with local statutory regulations and re-
quirements.
6.2.4 Measuring the supply flow pressure
Requirements
■
A gas shut-off device is installed at the customer's premises.
■
'Measuring the supply flow pressure'.
Materials required
■
pressure meter
Measuring the supply flow pressure
1.
Measure the supply flow pressure at the valve (1) of the gas valve on the fan
burner.
2.
Compare the measured value with the specified limits; see 'Gas specification'.
Result:
■
If the measured supply flow pressure is lower than the specified values:
■
Notify the gas provider. In this case the appliance must not be put into
use and the gas supply must be switched off.
■
If the measured supply flow pressure is higher than the specified values:
■
Reduce the supply flow pressure.
6.2.5 Measuring the exhaust gas values
Materials required
■
Exhaust gas analyser
Measuring the exhaust gas values
1.
Guide the measuring sensor (2) of the exhaust gas meter (1) into the exhaust
outlet (3) for the burner to be measured.
2.
Measure the exhaust gas values.
Follow the operating instructions for the meter when taking the readings.
Additional information:
If the meter indicates approx. 21% O
2
or nothing at all, then the sensor is in-
side the wrong exhaust outlet.
