Verify the type of gas supply to be used, either natural or LPG, by checking the gas type label on rear panel of the unit and the serial label behind the drip pan handle on the right-hand side. For gas consumption data, see the rating label on the rear panel of the unit. Never connect an unregulated gas line to the appliance. You must use the gas regulator provided with the unit, even if the supply is controlled.
If the unit is being connected to a reticulated gas supply, an installer-supplied gas shut-off valve must be in- stalled in an easily accessible location. All installer supplied parts must conform to local codes, or in the absence of local codes, with the the requirements of the current version of AS/NZS 5601.1 and any other applicable statu- tory regulations.
All pipe sealants must be an approved type and resistant to the actions of LPG gases. Never use pipe sealant on flare fittings. All gas connections should be made by a qualified gas fitter and in accordance with local codes and ordinances. In the absence of local codes, the installation must comply with the the requirements of the current version of AS/NZS 5601.1 and any other applicable statutory regulations. Gas conversion kits are available from Customer Care. See section ‘Service’ for contact details. When ordering gas conversion kits, have the model num- ber, and the type of gas (natural or LPG) from your grill.
The appliance and its individual shut-off valve must be disconnected from the gas supply piping system dur- ing any pressure testing of that system at test pressures in excess of 3.5 kPa (1/2 PSIG). The appliance must be isolated from the gas supply piping system by closing its individual manual shut-off valve during any pressure testing of the gas supply piping system at test pressures equal to or less than 3.5 kPa (1/2 PSIG).
Natural Gas Hook Up:
THIS TYPE OF CONNECTION SHOULD BE PERFORMED BY A CERTIFIED OR LICENSED GAS FITTER ONLY.
WHERE THREADS ARE USED FOR CONNECTION TO THE APPLIANCE, ALL UNION MATING SUR- FACES SHALL BE COMPATIBLE AND COMPLY WITH AS ISO 7.1 OR AS 1722.2
Connection: Grills set for use with Natural gas come with an NG regulator assembly which has a short section of hose already connected. The regulator has a test point. The regulator assembly is not connected to the appliance. A certified gas fitter needs to connect the appliance to the gas supply. Shut-off valve and Gas fittings for rigid piping connection are not supplied with the appliance -- they must be provided by the installer.
For built-in installation with connection to Natural Gas:
- Attach regulator hose assembly to the appliance using the 3/8” SAE 45 Flare connection.
- Plumb from the female 1/2” BSP side of the regulator to gas supply.
- Do leak test.
- After the connection is completed, turn the shut-off valve on and turn the burner control valves on the unit to the “HI” position for about 20 seconds to allow the air in the system to purge, turn valves off and wait 5 minutes before attempting to light the burners.
For units mounted on a mobile cart and being connected to a reticulated supply of Natural gas, and where a quick- connect device is used, ensure that:
- The quick-connect device is certified to AS4627 and the gas hose assembly is certified to AS/NZS 1869;
- Limited flexibility connectors is certified to AS 4631.
- The gas fittings and hose assembly are compatible with the gas supply system and is able to deliver the maximum gas rating requirement of the DCS Outdoor Grill;
- All gas installation works are carried out in accordance the the AS/NZS Gas Installations Standard AS5601 and other applicable Standards; and
- Verify that connections are leak tested.
Natural Gas Hook Up Cont:
Where the appliance is intended to be permanently connected to a reticulated supply of gas, the appliance inlet connection shall have a thread in accordance with AS ISO 7.1
For grills mounted on a mobile cart and being connected to a reticulated supply of Natural gas, the installer must ensure that a restraining device that is no longer than 80% of the length of the hose is fitted with an eyebolt within 50mm of an external quick connect device, (as required by the current version of AS/NZS 5601.1) in order to prevent tension on the flexible hose in case the cart should move during use. Quick con- nect devices should be certifed to AS4627 and Gas hose assemblies should be certified to AS/NZS 1869.
Operating pressure: 1 kPa Supply pressure: 1.25 kPa to 3.5 kPa. If in excess of 3.5 kPa, a step down regulator is required. Check with your local gas utility company or local codes for instructions on installing gas supply lines. Be sure to check on type and size of run (refer to the current version of AS/NZS 5601.1 for pipe sizing details), and

how deep to bury the line. If the gas line is too small, the grill will not function properly. Any joint sealant used must be an approved type and be resistive to the actions of LPG gases.
Checking the Gas Pressure
Turn off the gas supply.
Connect the pressure gauge to the pressure test point. This can be done by either removing the test point screw on the NG regulator or by removing one of the burners and measuring the test point pressure at the injector.
Once the gauge is in position, turn the gas supply on.
Ignite all grill burners and turn the knob to the “HIGH” position. Check that the reading measures 1.00 kPa for Natural Gas. If not, adjust the regulator to obtain the stated pressure.
Once the pressure is set, switch off the burner, turn off the gas supply, and disconnect the pressure gauge.
Ensure the Grill is returned to its normal operating state. Replace the screw in the NG regulator, or replace the burner if it has been removed. Perform a gas leak check on all gas connections to make sure there are no gas leaks at the test point or at any point in the connection to the inlet manifold.
LPG Gas Hook Up
Grills set for use with LPG gas come equipped with a high capacity hose/regulator assembly for connection to a standard 9 kg LPG POL cylinder. The LPG cylinder is not included.
Connection: 1/2” NPT male with a 3/8” Flare adapter (included). LPG Hose with a POL fitting and fittings are included. Operating pressure: 2.75 kPa. Maximum supply pressure: 1750 kPa.
Before connecting LPG cylinder to regulator, check that all knobs are in the OFF position and open grill hood.
To connect the LPG regulator/hose assembly to the cylinder/valve assembly, first make sure the main valve on the cylinder is completely closed. You should always turn off the LPG cylinder main valve (Fig. 12) after each use and during transport of the cylinder or unit. Insert the regulator inlet into the cylinder valve and turn clockwise until the coupler tightens up. Do not overtighten the coupler. Turn the main cylinder valve on and turn the burner control valves on the unit to the “HI” position for about 20 seconds to allow the air in the system to purge, turn valves off and wait 5 minutes before attempting to light the burners.
To disconnect the coupler, first make sure the main cylinder valve is turned off. Grasp the coupler and turn counter clockwise. The inlet will then disengage. Remove the inlet from the cylinder valve opening if it has not already done so when it disengaged. Your local LPG filling station should be equipped with the proper equipment to fill your cylinder.
LPG Cylinder Requirements:
A dented or rusty LPG cylinder may be hazardous and should be checked by your LPG supplier. The cylinder that is used must have a collar to protect the cylinder valve. Never use a cylinder with a damaged valve. Al- ways check for leaks after every LPG cylinder change. The LPG gas cylinder must conform to AS2030.1:2009 and designed for use with a POL fitting only. Do not change the regulator/hose assembly from that supplied with the unit. The cylinder must be provided with a shut-off valve terminating in an LPG gas supply cylinder valve outlet specified, as applicable, for POL connection. If the appliance is stored indoors, the cylinder must be discon- nected and removed from the appliance. Cylinders must be stored outdoors in a well-ventilated area out of the reach of children.
When an LPG unit is being directly connected to an LPG house system, you must follow the natural gas hook up guide- lines. The installer must provide the proper gas regulator to reduce the gas flow to 2.75 kPa.
The Grill comes with the LPG Regulator/Hose assembly installed at the factory. The assembly, along with the entire Grill system, is leak tested. Do not remove the Regulator/Hose assembly from the Grill during installation.
- Do not remove the Grill from the pallet until you are ready to install.
- Do not place the Grill directly on the ground or any other flat surface without support. This will prevent damaging the regulator/hose assembly by the weight of the grill.
- Check the hose, regulator and connectors for damage. Look for cracks, abrasions, brittleness, holes, dents and nicks.
- Do not attempt to remove, repair, or replace the Regu- lator/Hose assembly by yourself. It must be done by a qualified licensed gas fitter only.
