INSTRUCTIONS FOR THE INSTALLER
TESTING FOR CORRECT PRESSURE OF GAS
Before attempting to light burners, it is necessary to
ascertain that the correct and desired pressure of gas
is arriving at the appliance.
The test is carried out by removing screw (A) from the
test point (B) and attaching a water gauge tester by
rubber tube to the test point. Turn on the gas and
ascertain the pressure being received (NATURAL GAS,
20 mbar, BUTANE, 28-30 mbar or PROPANE, 37 mbar).
Should the pressure be lower or in excess of the desired
pressure then the installer should consult the gas
supplier. With LP Gas, the installer must ensure that the
correct regulator is fitted and particular attention should
be made when one or more appliances are operating at
the same time so as to obtain correct reading at the
test point on the cooker. Once the correct pressure has
been ascertained, replace screw (A).
After ensuring that the correct gas pressure is being
supplied to the appliance and if the appliance is to be
operated with natural gas, you can now proceed to light
the burners to ascertain that they are burning correctly.
If the appliance is to be converted for use with L.P. gas,
please follow the conversion instructions prior to testing
the hotplate burners.
