If you use a lot of gas at home or in your cabin, you should consider getting a plumbed-in gas system. Here is an overview of what you are allowed to do yourself, and what you must leave to the professionals.
As an unqualified person, you are only allowed to fit a gas hose up to 1.5 metres long, with a regulator, between a propane bottle and a gas appliance, such as a stove or barbecue. You are not allowed to run a gas hose through walls. If you need to run gas through walls, it must be fed through a properly installed pipe, and this must be left to the professionals. This applies to gas pipes of every type.
If the gas appliance has a shut-off valve, gas pipes, tanks or evaporators, again, you must leave the job to the professionals.
You are allowed to install gas detectors and carbon monoxide detectors, provided that these have batteries or will be plugged into a socket. Remember to check the user instructions to make sure you're installing the detector in the right place. Leak detectors that are fitted to gas pipes must be installed by professionals.
You can install external gas storage cabinets yourself. External gas storage cabinets must be made of non-flammable material, such as steel. The gas bottles must be stored in an upright position and must not be able to fall over. The cabinet must be kept locked.
If you intend to store gas outdoors for use in winter, you should choose gas bottles made from steel rather than composite material (lightweight bottles). If your gas consumption is high and the temperature around the bottle is extremely low, this could result in too little gas being fed to the gas appliance.
