Checking the gas supply
1. Check the manometer zero point is correct.
2. Connect the manometer to the cooktop pressure point.
This is located on the regulator.
3. Turn on the gas supply and electricity and try to ignite
the gas.
TIPS & INFORMATION
NOTE! It will take additional time to light the gas for
the first time as air needs to be purged from the pipes.
4. With the appliance operating check the outlet pressure
• when all burners of the appliance are operating
at maximum,
• when the smallest burner of the appliance
is operating at minimum.
Under these conditions the outlet pressure should not
vary from the nominal outlet pressure of 1.00kPa by
more than +/– 0.20kPa.
If the regulator appears to not be performing satisfactorily,
then check the following points.
1. If the outlet pressure is consistently too low then the
inlet pressure may be too low and adjustment of an
upstream regulator may be needed, or an upstream
regulator or valve with insufficient flow capacity may
be present in the gas supply line. If this is suspected
then it may be necessary to repeat the checks whilst
measuring both the inlet and outlet pressure to determine
if the inlet pressure is in the range 1.13 – 5kPa.
2. Check that the regulator has been fitted to the gas
supply line in the correct orientation, the arrow on the
base of the body indicates the direction of gas flow.
Once these checks have been completed, if the
regulator still fails to perform in a satisfactory manner
it should be replaced.
