INSTRUCTIONS FOR THE INSTALLER
Natural Gas. The appliance installer is not required
to make an adjustment to obtain the correct outlet
pressure setting.
An arrow on the base of the regulator indicates
the direction of gas flow when the inlet and outlet
of the regulator is orientated correctly. When the
regulator has been fitted check for leaks from the
connections with soapy water.
Gas Connection
This appliance is supplied for use with Natural
Gas. However, it can be converted for use with
LPG. Refer to LP conversion chapter.
Supply pipe sizing
The total hourly gas consumption for the appliance
is shown on the data label. The required supply
pressure (i.e. at inlet to appliance regulator) for
each gas type is shown on the data label, and
given in page "TECHNICAL CHARACTERISTIC
TABLES". Use this information in conjunction with
the length of run, number of elbows, tees and
bends, the available service pressure and the
supply requirements of other installed appliances
to determine a suitable pipe size. For assistance
in this matter refer to the appropriate section of the
Installation Code AS5601.
An AGA certified class B or D flexible connection
may be used to connect the cooktop in accordance
with the AS5601 and in particular section 4.8.
Where a hose assembly is used and the cooktop
is in the installed position, the hose assembly shall
be suitable for connection to a fixed consumer
piping outlet located at a point 800 - 850mm above
the floor and in the region outside the width of the
appliance to a distance of 250mm. The point of
connection to consumer piping must be accessible
with appliance installed.
Elbow positioning
It is possible to reposition the elbow if required by
loosening the locking nut and elbow by using two
spanners. Re-tighten the entire assembly after the
elbow has been repositioned. When fitting elbow to
appliance, ensure that the sealing washer is fitted.
Regulator
An appliance regulator is provided. The regulator
must be positioned so that the pressure test nipple
is accessible when the appliance is installed.
Connect the gas supply to the ½” B.S.P. internal
thread inlet of the regulator (fig.7).
Assembly of Regulator
The assembly of the regulator to the cooktop
manifold is achieved via the elbow union and
sealing washersupplied.
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 with
Natural Gas.
The appliance installer is not required to make an
adjustment to obtain the correct outlet pressure
setting.
An arrow on the base of the regulator indicates the
direction of gas flow when the inlet and outlet of the
regulator is orientated correctly. When the regulator
has been fitted check for leaks from the connections
with soapy water.
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. NOTE! lt 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 perform
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 fhe 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 regulafor 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.
