EasyGas DownUnder Abridged Installation Guide

The following is an abridged version of the EasyGas DownUnder™ installation intructions.  

Elgas provides free training for EGDU installation.  A complete version of  EasyGas DownUnder Manual is supplied to you when you complete the required training, all at no expense to you. 

Please contact your Elgas representative if you are interested in attending a free EasyGas Downunder training session.


  • Placement should provide unobstructed access from the nearest street
  • Not to be located within 1m of a vent, drain, window, door or electrical appliance
  • Position cylinder pit so there is no possibility of water accumulation.  The location is chosen with consideration for the overall terrain and cylinders are not installed in depressions or locations which are not well drained or are subject to inundations.
  • The underground system should not be positioned where it will be subject to heavy or regular loading of the lid.
  • Excavate a hole 800mm diameter x 1500mm deep Ensure the base is level and compacted.
  • The canister top needs to be flush with the finished ground level.  Note: this excavation is deemed to be a confined space and all necessary precautions shall be taken to work within the excavation.
  • Lower the canister base assembly in the excavation.
  • The bottom section of the plastic canister shall be held onto the ground by external concrete ballast. Pour concrete mix around the canister bottom to secure as an anchor.
  • Ensure that the canister assembly is kept in a vertical and true position at all times.
  • A minimum 0.14 cubic metres (15 x 20 kg concrete bags) of concrete anchor is required to keep the base, in clay soil. Installation in sandy soils may need additional concrete.
  • Backfill the remaining voids up to the the top of bottom section of the canister with crushed soil or sand. The remaining gap to the finished ground level may be filled after cylinder installation.
  • Remove Lid and canister top. Inspect the pit to ensure that it is clean from any water, debris etc.
  • Lower 90kg galvanised cylinder assembly supplied by Elgas. Avoid manual handling of the cylinder, as the tare weight of the cylinder assembly is approximately 75 kg.
  • Fill the void between the plastic canister and the cylinder with clean builder’s sand, up to the top of the canister (make sure that no organic material is mixed with the sand).
  • Place canister top back to the base and secure it with 6 off 6-mm stainless steel bolts
  • The Cylinder is now ready for gas piping connections.
  • Connect copper pipe (pigtail) from the outlet valve to the regulator. Regulator must be supplied by the fitter and be appropriately rated for the household load.
  • Draw the Polyethylene gas supply line through the opening on the cylinder valve protection ring. Connect the gas supply line onto the regulator with appropriate fittings.
  • Note: As the cylinder is cathodically protected (galvanised) copper supply lines shall be fitted with an insulating kit inside the cylinder VPR to maintain electrical isolation.
  • Compliance Plates (NSW only) - the person responsible for carrying out of gas fitting works must attach a Compliance Plate to the installation after the work is completed.
  • For all Easygas Downunder installations, the Compliance Plate must be attached to the internal face of the cylinder’s neck ring, using high strength industrial adhesive
  • Householders and general public  must be aware of the potential hazards in storage of LPG cylinder. Suitable warning labels are fixed onto the lid.
  • To prevent electric equipment (Lawn mowers and others) from damaging the plastic lid and from getting too close to the LPG equipment, a concrete protection collar around the lid is desirable.
  • A precast concrete collar of 50 x 700 mm is recommended around the canister top opening.
  • Elgas tanker drivers will fill the cylinders.
