ASSEMBLY OF THE REGULATOR
The assembly of the regulator to the cooktop
manifold is achieved via the elbow union and
sealing washer supplied, refer to Figure 7.
The ½" parallel thread connects to the
manifold, and the sealing washer is placed
between the manifold end and the flat face on
the elbow.
The ½" tapered thread connects to the
outlet of the regulator, and is sealed on the
thread using approved thread sealing tape or
approved thread sealing compound.
The inlet of the regulator is a ½" parallel thread
and is connected to consumer piping
or hose assembly.
Regulators are supplied pre-adjusted and
configured by the component maker for use

A full operational test and a test for possible leakages must be
carried out by the fitter after installation.
CHECKING THE GAS SUPPLY
• Check the manometer zero point is correct.
• Connect the manometer to the cooktop
pressure point. This is located on the
regulator.
• Turn on the gas supply and electricity and
try to ignite the gas.
NOTE: It will take additional time to light the
gas for the first time as air needs to be purged
from the pipes.
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:
• 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
