The stove connection set consists of a pressure regulator/pressure reducer, piping, an elbow and the hose assembly for connection to the gas stove. The hose assembly supplied is limited to 40 centimetres. It may not be any longer.
The Technical Rules for LPG (TRF) are relevant for private LPG systems. The regulation states that rubber or plastic hose assemblies must not exceed 40 centimetres. In this respect, the initial question must be answered with a clear no. If you replace the existing hose assembly, you must install a new one that is no longer than the maximum permissible 40 centimetres.
If you want to bridge larger distances, you must extend the piping. In the stove connection set (image), we deliver a standard pipe with a length of 40 centimetres. You can extend the pipe to the required dimension via a compression fitting and an additional piece of pipe.
Please observe our note that the work on the system described above may only be carried out by a qualified person.
