INSTALLATION
GAS HOOKUP
NATURAL GAS HOOK UP CONT:
Important!
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 (as required
by AS/NZS 5601.1:2010) in order to prevent tension on the flexible hose in case the cart should move during
use. Detailed instructions and requirements are packed with the ‘quick connect’ flexible hose accessory kit.
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 AS/NZS 5601.1:2010 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
1. Turn off the gas supply.
2. 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.
3. Once the gauge is in position, turn the gas supply on.
4. Ignite the 2 grill burners furthest away from the gauge 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.
5. Once the pressure is set, switch off the burner, turn off the gas supply, and disconnect the pressure gauge.
6. 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.
