Domestic LP Gas Installations

Installation Regulations:

If you have a current installation or are planning a new installation, please familiarize yourself with the following basic regulatory requirements:


External Gas Storage:

The drawing below indicates the minimum requirements with regard to storage of cylinders.  Special care must be taken when deciding on the location for the cylinder storage.

Further to the above, the following must be adhered to:

  • Any Electric Motor or Switch Box must be a minimum of 5m away from the cylinder storage area.
  • Specialized piping must be used when building the gas pipeline.  Normal plumbing piping may not be used.
  • Where pipes are concealed (running through walls or under floor) special care must be taken to ensure compliance to set regulations. No joints are allowed in any concealed location.
  • The use of specialized flexible hose is limited to 2m.
  • Gas cylinders may NOT be stored in a garage.  Ventilation to the area where the cylinders are stored is key.
  • All materials and appliances used and installed must be SABS and SANS approved.
  • Cylinders must be stored on a slid level surface.  Special care must be taken to secure the cylinders.  This can be done by means on a chain system or the use of a gas cage.
  • Thatch Roof House:  A separate set of rules applies to the storage of Gas Cylinders on site which is applicable to Thatch roof homes.  Similar to the above, except that the gas cylinders must be stored behind a purpose built fire wall.  The cylinder storage must not be closer than 3m from the roof edge.  Please contact me for further information and guidance around these requirements.


Indoor Gas Storage:

The option to store a Cylinder inside the residence is a possibility.  The home owner is however limited to store 9kg gas inside the house.  The downside in storing the Cylinder inside the house is that you will lose one cupboard space as the cylinder must be stored inside its own ventilated cupboard. 

The positive to this method is cost.  Small installation with minimum pipe run.  

Some regulatory requirements must however be considered:

  • Rubber pipe (Orange hose) may not pass through any partition. 
  • Spacing of plug points
  • Allowance for airflow through the cupboard
  • Service and shut off valves must be allowed for
  • Airflow or ventilation for any indoor installation is critical. 
  • Below is a basic drawing of the requirements linked to an indoor installation:
