12 GAS CONNECTION
OPERATION ON N.G./S.N.G.GAS CONNECTION
WARNING
CAUTION
This appliance is supplied for use with Natural Gas.
However, it can be converted for use with LPG.
Refer to LP conversion on pages 12 and 13.
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 Technical Data
table. 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 AS/NZS 5601.1 or AS/NZS 5601.2.
An AGA certified class B or D flexible connection may be
used to connect the cooktop in accordance with AS/
NZS 5601.1, in particular section 5.9 and clause 6.10.1.8,
or AS/NZS 5601.2, in particular section 2.11. 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 ” B.S.P. internal thread inlet of the regulator. Refer to
‘bench cutout’ (Figure 4) for connection point position.
Assembly of Regulator
The assembly of the regulator to the cooktop manifold
is achieved via the elbow union and sealing washer
supplied, refer to figure 9 (page 11).
The
” parallel thread connects to the manifold,
and the sealing washer is placed between the
manifold end and the flat face on the elbow.
The
” 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
” 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.
TIPS & INFORMATION
IMPORTANT
It will take additional time to light the gas for the first
time as air needs to be purged from the pipes.
