GAS CONNECTIONGAS CONNECTION

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

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.

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

NOTE! It 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.

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.

If the regulator appears to not be performing 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 the 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 regulator 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.

Once these checks have been completed, if the

regulator still fails to perform in a satisfactory manner

it should be replaced.
