GAS Connection

OPERATION ON N.G./S.N.G.

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 Table 2.

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. 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 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.
