THE DOMESTIC INSTALLATION
Is my installation legal?
- Do I possess a Certificate of Conformity ?
Here are a few laws concerning Domestic installations
- The “orange”-hose connection may not be longer than 2 meters, may not have any joints or pass through any walls, partitions or ceilings and may not be used outdoors as it is not UV-resistant unless such cylinder and hose is protected against the elements. A wire braided pigtail hose with a bullnose fitting should be used outdoors and must be used on cylinders exceeding the gas capacity greater than 19 kg.
- All LP Gas installations must have a main safety valve and isolation valves at or near the appliances.
- Cylinders shall not be installed less than 3 meters from thatch roofs and must be placed behind a firewall.
- No LP Gas reticulation may run through a roof unless it is enclosed in a steel sleeve with no joints used. Corrugated stainless steel piping (trac pipe) with no joints, may also be used.
- All LP Gas installations must be installed with the reticulation of the correct standard of piping which includes in most and many domestic environments as copper tubing which will not be a lower grade than class 01. It is absolutely unacceptable by law to use class 00 which is used by plumbers for most domestic plumbing installations.
- Composite tubing used for gas installations is ideal for unexposed internal uses such as in concrete slabs, chased into walls or underground trenching. For exposed reticulation the use of copper piping and scheduled steel piping is ideal.
- When cross-linked polyethylene (PEX) composite tubing is exposed to ultraviolet light (sunlight) for extended amounts of time, PEX piping can become brittle and break, just like any plastic pipe. Even PEX pipe containing ultraviolet stabilizers can only be exposed to sunlight for up to 6 months. For outdoor use PEX piping must be used in a protective sleeve.
- See the laws concerning the positioning of cylinders, which is critical to safety, in the diagrams that follows.
