Connecting the cooker to the gas supply

  • The gas connection must be carried out by an authorised person according to the relevant standards.
  • Before connecting the appliance to the gas main, mount the brass conical adaptor onto the gas inlet pipe, upon which the washer has been placed (see Figs. 7-8 following).
  • Conical adaptor and washer are supplied with the appliance (packed with conversion kit for use with Natural gas or LPG).
  • This appliance is suitable for use with Natural gas or LPG. (Check the “gas type” sticker attached to the appliance).
  • For Natural gas, connect the gas supply to the gas pressure regulator which is supplied with the appliance (Fig.8). Adjust the regulator to obtain a test point pressure of 1 kPa with the two semi- rapid burners operating at the maximum.
  • For LPG, connect the gas supply to the test point adaptor which is supplied with the appliance (Fig.7). Ensure that the supply pressure is regulated to 2.75 kPa.
  • The connection must be made at the rear of appliance (left or right); the pipe is not to cross the cooker.
  • Close off the unused inlet with the cap and sealing washer supplied (Fig. 10).

Use two spanners to tighten or loosen the connecting pipe (Fig. 9).

Installation with a flexible hose assembly

  • If this appliance has to be installed with a hose assembly, the installer shall refer to the network operator or gas supplier for confirmation of the gas type, if in doubt.
  • When used with a flexible hose, the connector on the wall should be between 450 mm to 500 mm from the floor and 200 mm to 300 mm from the left-hand side of the appliance as viewed from the front. The hose connection on the appliance shall face downwards.

Fig. 8 Natural gas connection

  • It is important that the hose does not come in contact with the metal of the appliance and is secured as per appropriate gas installation codes. A chain 80% of the length of the flexible gas hose must be used to prevent stress being applied to the hose. The chain should be attached securely to the product where shown (see Fig.10), and on the wall.
  • Flexible hose assemblies should be AS/NZS 1869 Class B or Class D certified. The thread connection shall be Rp 1⁄2” (ISO 7-1) male.

After connection the installer must check that the hose is not kinked, subjected to abrasion or permanently deformed. The installer must check also that the hose is not near (or in contact with) any hot surfaces.

  • The hose assembly shall be as short as practicable and comply with relevant AS5601NZS5261 requirements.

Leak-testing and flame-testing the cooker

After installing the freestanding cooker and connecting the gas supply:

  1. Using a suitable leak detection fluid solution, check each gas connection one at a time by brushing the solution over the connection.
    The presence of bubbles will indicate a leak. If there is a leak, tighten the fitting and then recheck for leaks.

Do not use a naked flame to test for leaks.

  1. Adjust the test point pressure or supply pressure to the value that is appropriate for the gas type.

  2. Test the operation of the appliance:

  • Turn on the appliance gas controls and light each burner individually and in combination. Check for a well-defined blue flame without any yellow tipping. If any abnormality is evident, then check that the burner cap is located properly and the injector nipple is aligned correctly.
  • Check the minimum burner setting by quickly rotating the gas control knob from the maximum to the minimum position. The flame must not go out. If you need to adjust the setting, see ‘Adjusting the minimum burner setting’ following.
  1. If satisfacfory performance cannot be obtained, the installer shall check the installation and notify the local gas supply authority for a gas supply problem, or if it is an appliance problem, our Customer Service Centre should be called to obtain the nearest authorized Service Agent.

Converting to a different gas type

This appliance is suitable for use with Natural gas or LPG (check the “gas type” sticker attached to the appliance). To convert from one gas type to another, you need to replace the injectors, and then adjust the minimum burner setting.

Replacing the injectors

  1. Remove the trivets and burners from the cooktop.

  2. Using a spanner, remove the injector (shown in Figs. 11-12 following) and replace it with one according to the gas type (see the ‘Table for the choice of injectors’).

  3. Fix the warning label (supplied with the conversion kit) at the back of the cooker, near the gas inlet connections. This label states that the gas cooktop has been converted for use with LPG/ Natural gas.

Adjusting the minimum burner setting

  1. Follow the instructions on ‘Adjusting the minimum burner setting’.
  • If you are converting the cooker from Natural gas to LPG, remove the gas pressure regulator before connecting the cooker to the gas supply and replace with the test point adaptor supplied with the conversion kit.
  • If you are converting the cooker from LPG to Natural gas, remove the test point adaptor before connecting the cooker to the gas supply and replace with the gas pressure regulator supplied with the conversion kit.

The burners are designed so that regulation of primary air is not required.

Adjusting the minimum burner setting

Check whether the flame spreads to all burner ports when the burner is lit with the gas valve set to the minimum position.

If some ports do not light, increase the minimum gas rate setting. Check whether the burner remains lit even when the gas valve is turned quickly from the maximum to the minimum position. If the burner does not remain lit, increase the minimum gas rate setting.

To adjust the minimum gas rate setting:

  1. Turn on the burner.

  2. Turn the valve to the MINIMUM position.

  3. Take off the knob.

  4. Using a small flat screwdriver, turn the screw (see Figs. 13 or 14) to the correct regulation.
