GAS CONNECTION

OPERATION ON N.G./S.N.G.GAS CONNECTION

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 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 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 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.
