9 Frequently Asked Questions
Firstly, because campervan gas regulations and requirements are such a grey area, we thought we’d start by answering the 9 most commonly asked questions:
1. What are the current campervan gas regulations?
The most up to date regulations covering LPG gas in campervans are:
BS EN 1949:2021
Gas Safety (Installation & Use) Regulations 1998 (GSIUR).
See the Regulations section below for more details and to download a copy.
The standards are typically reviewed every 5-10 years.
2. How much gas can I legally carry onboard my campervan?
The BS EN 1949:2021 states the maximum amount of cylinders within a cylinder compartment is two, with a capacity of 16kgs each. Please refer to the cylinder compartment regulations below.
However, LPG tanks are different. They have restrictions but only when the gas is used for the propulsion of the vehicle. Therefore, we recommend installing an underslung gas tank that is designed for your vehicle.
3. Can I install gas in my campervan if I’m not a qualified gas engineer?
Anyone can install gas to their campervan as long as it’s for personal use only, and they are ‘competent’ enough to do so.
‘Having the necessary ability, knowledge, or skill to do something successfully.’
Gas Safety (Installation & Use) Regulations 1998 (GSIUR) states: ‘Competence is a combination of practical skill, training, knowledge and experience to carry out the job in hand safely, and ensuring the installation is left in a safe condition for use. Knowledge must be kept up to date with changes in the law, technology and safe working practice.’ – Guidance 3(1)–(2)
In other words, someone competent would be expected to install gas to the same level as a gas engineer and adhere to current requirements.
However, suppose the camper is being rented out. In that case, anyone who does work on the campervan needs to be competent, be aware of the current standards and hold relevant qualifications. Therefore, a qualified gas engineer registered with Gas Safe would be required.
Furthermore, if you’re renting out a camper, you are classified as a landlord. So, an appropriate certificate must be issued (we cover this below).
In fact, you can’t rent out your camper without this certificate.
4. Does installing campervan gas for personal use mean you don’t need to use a qualified gas engineer or have the installation signed off?
According to law and regulations, this is correct! However, this doesn’t mean you can do what you like (like using a garden water hose for a gas pipe!). You must follow the current campervan gas regulations to ensure the system is safe.
In the unfortunate event of something going wrong or if there’s an accident, the installer (you!) would be liable. In this case, you must prove your competency via inspection of your installation. As a result, you may face prosecution if the gas system doesn’t meet the regulations and is deemed unsafe.
This is not to discourage anyone from installing gas themselves. It’s purely to make sure people are aware of the implications and to promote health and safety.
Therefore, with the correct help and guidance, anyone can install campervan gas correctly and safely. However, if you’re not confident or competent, we strongly recommend using a qualified gas safe registered engineer.
5. If I install my campervan gas system, will a gas engineer sign it off?
Yes, of course! However, some gas engineers may refuse to sign off other people’s work because it would make them liable.
Nevertheless, there are plenty of engineers who will sign off other peoples work. Additionally, some gas installation companies offer this service.
The engineer must be Gas Safe registered and qualified to work on campervan gas and LPG. In addition, the engineer will need to carry out a full inspection of the system to ensure it meets current regulations. Subsequently, they will issue a gas certificate.
6. What gas certificate is required for renting out a campervan?
Gas Safe answer: ‘A Gas Safety Record similar to the ones used for Landlord gas safety checks in permanent dwellings would be suitable. The vehicle registration would be recorded instead of a property address.’
A record shall include:
Regulation 36 – Duties of Landlords
7. Is a DIY cylinder compartment acceptable within a campervan, or does it need to be a pre-fabricated metal compartment?
DIY gas lockers are acceptable as long as they comply with BS EN 1949:2021.
8. How do I find a qualified gas safe engineer?
Whether you need a qualified Gas Safe engineer to carry out gas installation work or sign off your existing gas installation, there are many ways to find one.
One way is to search forums and Facebook groups to find people who’ve had gas work carried out on their campervan and recommend the engineer. Although, be aware that unqualified engineers do advertise on these platforms. Therefore, it’s important to check the engineer is qualified and Gas Safe registered (this is covered in the next FAQ)
The best way is to use the Gas Safe Register website. There, you can find local gas engineers and see if they’re qualified to work on campervan and LPG gas systems.
Simply go to the Gas Safe register website and follow these steps:
– Under ‘Find and check’, make sure Find is selected.
- – Type your postcode into the search box.
– Make sure ‘Domestic’ is selected and click ‘Search’.
– Select ‘Liquid Petroleum Gas (LPG)’ under ‘Fuel Type’.
– Click the dropdown ‘Appliance Type’ and select ‘CARAVANS pipework LAV LPG (CORE)’. Ensure you press ‘Filter Results’ at the bottom.
– Click ‘Update Results’.
– Once the page has loaded, scroll down and you will see all the companies relating to your search criteria. They include the company name, address, registration number, phone number, email and distance from your postcode.
– Find a company and click ‘View Services’.
– Here, you will see the services the company is qualified to work on. Check that ‘CARAVANS Pipework LAV LPG (CORE)’ is selected under the LPG column.
– Additionally, go ‘< Back to results‘ and click on ‘View Engineers’ this will show you an image and details of the engineer/s employed by that company.
9. How do I check if an engineer or business is Gas Safe registered?
Gas Safe answer: ‘Check if a business is Gas Safe registered on our website. This is just because we do get unregistered gas workers advertising on internet forums and Facebook unfortunately, so we would just want to ensure that consumers are aware of the importance of checking their registration before they use them.’
Simply go to the Gas Safe register website and follow these steps:
– Go to the Gas Safe Register home page and select ‘Check’ .
– Enter your search term and click ‘Search’.
– From here you can check all the details of the engineer or business.
The rules, regulations and guidelines don’t mention the word ‘campervan/s’. So, whats defined as a campervan?
Below are the definitions of leisure accommodation vehicles mentioned in the rules, regulations and guidelines.
LAV (Leisure Accommodation Vehicles)
Tourers, motor caravans, motorhomes, and caravan holiday homes are all considered as leisure accommodation vehicles. An LAV is a type of living space that can be occupied temporarily or seasonally, and it is designed to meet the construction and usage requirements of road vehicles.
The definition of ‘LAV’ covers touring caravans that are generally towed behind a suitable vehicle and motor caravans, which by their nature are self-propelled. Holiday homes are also covered by the definition of ‘LAV’. These are specifically designed for holiday accommodation and may come in various designs, from the traditional caravan to ‘log’ cabins.Technical Bulletin 063 (Gas safe register) 19 Aug 2010
Campervans are self-propelled vehicles with living and sleeping accommodation. They are typically converted from a van, so they’re smaller and simpler than motorhomes (motor caravan).
Motor Caravan (Motorhome)
Motor caravans are self-propelled leisure accommodation vehicles with coach-built bodies. They have seats, a table, sleeping accommodation (which may convert from the seats), cooking facilities, a toilet and storage facilities.
Typically, motor caravans are much larger than campervans and are made by professional companies.
Caravans are leisure accommodation trailers, towed behind a suitable vehicle.
Caravan Holiday Home
Transportable leisure accommodations that are moveable but do not meet requirements for use on the road.
Campervan Gas Regulations And Legal Requirements
BS EN 1949: 2021
Specification for the installation of LPG systems for habitation purposes in leisure accommodation vehicles and accommodation purposes in other vehicles.
BS EN 1949:2021
The BS EN 1949:2021 regulations replaced the previous BS EN 1949:2011+A1:2013 version, which is now withdrawn.
It details the health and safety requirements of the installation design, components, appliances, connections, pressure, cylinder compartments, flue, tightness and testing.
Not included in these British standards:
Alternatively, save yourself a few hundred quid! All the campervan related information from the regulations, is detailed below.
The Gas Safety (Installation and Use) Regulations 1998
GSIUR deals with the safe installation, maintenance and use of gas systems, including gas fittings, appliances and flues, mainly in domestic and commercial premises.
The regulations apply to natural gas and liquified petroleum gas (LPG), as defined in the Gas Act 1998 (fifth edition 2018).
However, not all gas work on self-propelled vehicles falls under the GSIUR unless they are hired out to the public.
Additionally, the GSIUR includes guidance on defining competency (See Regulation 3 – Qualification and supervision, download the document below).
Relevant information from the regulations with respect to self-propelled vehicles (Campervans):
Regulation 2 (General interpretation and application)
(5) Nothing in these Regulations shall apply in relation to the supply of gas to, or anything done in respect of a gas fitting on –
(a) a self-propelled vehicle except when such vehicle is –
(i) hired out in the course of a business; or
(ii) made available to members of the public in the course of a business carried on from that vehicle
Regulation 3 (Qualification and supervision)
(1) No person shall carry out any work in relation to a gas fitting or gas storage vessel unless he is competent to do so.

HSE – Gas safety in caravans, including leisure accommodation vehicles and residential park-homes
Provides information and advice on the application of the Gas Safety (Installation and Use) Regulations 1998 (GSIUR) to leisure accommodation vehicles and residential park homes, and enforcement demarcation.
Specific to caravans (tourers), motor caravans and caravan holiday homes.
The HSE information can be found here:
All gas components, materials and appliances will have manufacturer instructions on installing them to a gas system. Therefore, you must read and adhered to these instructions.
Gas Safety Organisations
Gas Safe is the gas registration body covering the UK, Isle of Man and Guernsey. By law, all gas engineers must be on the Gas Safe Register.
Gas Safe replaced CORGI (Council for Registered Gas Installers) in April 2009.
Types Of Gas
Campervans use either Propane, Butane or LPG.
Propane and butane are very similar. Firstly, they’re both members of the LPG family. Also, they’re flammable hydrocarbon gases from natural gas processing and oil refinery.
The gas is liquidised into cylinders (AKA bottles) through pressurisation. Once the liquidised gas is released from the tank, it vaporises into gas.
However, they do have their differences:
Propane bottles have no standardised colour, but typically they’re red or sometimes orange.
Propane is best suited for use in colder climates because it will still vaporise into gas when the temperature is as low as -42˚C (boiling point)! Therefore, propane will remain a liquid if the temperature is below the boiling point.
This ability to vaporise at low temperatures means it’s better suited to external storage and use. In addition, propane produces more heat than butane in cold temperatures and is, therefore, more efficient.
It’s widely used in caravan parks, commercial and domestic properties. Also, it’s a good fuel source for campervans because it’s cheaper and more efficient than butane.
Butane bottles have no standardised colour, but typically they’re blue. However, yellow and white are also common.
Butane is better suited to warmer climates because it will only vaporise into gas when the temperature is above -2˚C (boiling point)! Therefore, butane will remain a liquid if the temperature is below this boiling point.
As well as Calor gas bottles, it’s available in Campingaz bottles that are much smaller, so they’re ideal for camping and smaller campervans. Therefore, butane is best suited to leisure trips for use in cooking, heating and BBQs.
Butane is a much safer gas when stored because it liquefies easily. Therefore it’s easier to contain, with lower pressures than propane.
LPG (liquefied petroleum gas) is a mixture of propane and butane. It is also liquified into a tank through pressurisation and vaporises into gas once released from the tank/cylinder.
However, the amount of each gas used to make LPG depends on the location. For example, colder climates will use more propane, whereas warmer climates will use approximately 50/50. Thus, resulting in different boiling points.
LPG is stored in an underslung gas tank or an internal LPG gas cylinder on a campervan. Additionally, the gas itself is much cheaper than propane and butane and widely available in the UK and Europe.

Whether in a van, a self-built campervan or a motorhome, travelling with liquid gas has its rules and limitations.
Ferry companies require that you adhere to their rules when carrying gas onboard your campervan.
Individual ferry companies detail rules on their websites, but you’ll find that most of them have the same requirements.
This information is sourced from Stena Line, Brittany Ferries and Irish Ferries websites. They require:
The gas MUST be turned off at the bottle/tank. Additionally, it must be accessible for the staff to inspect if required.
The Eurotunnel website states:
2.5.6 The maximum permitted volume and quantity of flammable gas cylinders and tanks per vehicle is:
For portable containers (cylinders/bottles, etc.): Maximum of 47kg per cylinder and no more than 50kg per vehicle if more than 1 container;
For fixed containers (tanks): Maximum of 47kg per container and no more than 50kg per vehicle if more than 1 container;
Fixed containers must be no more than 80% full. The capacity of the container will be checked by Eurotunnel staff.https://www.eurotunnel.com/uk/legal/carriage-of-dangerous-and-hazardous-goods/
The campervan gas regulations state that campervans can carry 2 cylinders with a maximum capacity of 16kgs each within a cylinder compartment. See the cylinder compartment regulations below for more details.
After extensive research and digging, we cannot find any restrictions on the legal amount of LPG that you can carry in a campervan. Although, the only information available is related to businesses transporting LPG bottles.
Also, it’s advisable to turn off the gas at the cylinder/tank when you’re driving.
As you know, using gas in a campervan can be dangerous. Therefore, you must follow these safety measures.
Carbon Monoxide Detector
Carbon monoxide (CO) is a colourless and odourless gas produced by a malfunctioning gas appliance. CO is poisonous! At best, breathing it in can cause flu-like symptoms; at worst, it will cause you to pass out or even kill you.
Therefore, you must install a CO detector in your van. So that it functions correctly, test it weekly and replace it before the recommended expiry date.
When installing gas in your camper, you must-have a fire extinguisher on-board. Although the dry powder type (blue label) is suitable for gas and electrical fires, it can ruin the inside of your van. On the other hand, water mist fire extinguishers are also suitable (yes, even on electrical fires) and won’t cause as much damage.
Additionally, fire blankets and smoke detectors are other forms of fire protection.
Be sure to check and make a note of their expiry dates; replace them before this date.
Also, test the smoke alarm weekly and replace the batteries before they run out to ensure it’s functioning correctly.
There are no requirements for campervans with gas onboard to display an LPG or compressed gas sticker to the vehicle’s exterior, unlike work vehicles.
Although, it is highly recommended because it notifies the emergency services that gas is present if your vehicle is involved in a road accident.
Cylinder compartments must have drop-out floor vents for any leaked gas to escape. LPG is heavier than air, so it falls to the floor, forming ‘puddles’ of gas that will escape out of the floor vent.
Additionally, although it’s not required, we recommend a floor vent is fitted below any fixed gas appliance (e.g. 3-way fridge, space heater).
It’s a good idea to have other forms of ventilation in your camper to ensure any unburned gas can escape safely. Our campervan ventilation guide will give you some ideas on the many types of ventilation.
Further Reading | The Ultimate Campervan Ventilation Guide
A gas cylinder must be contained inside a sealed compartment, separating it from the living space. Most motorhomes and caravans have a compartment accessed from the outside; however, this is not always possible in a self-build campervan.
This compartment needs to meet specific requirements for it to comply with regulations. For this reason, specifically designed gas lockers are available to buy. Discover what regulations apply to gas storage lockers here.
Current Campervan Gas Regulations UK
BS EN 1949: 2021 – ‘Specification for the installation of LPG systems for habitation purposes in leisure accommodation vehicles and accommodation purposes in other vehicles’.
The regulations are available to anyone but, unfortunately, come at a hefty price tag of a couple of hundred pounds.
So, they’re not easily accessible to anyone installing gas themselves who are still required to comply with them. Therefore, to ensure you’re compliant and safe, we’ve detailed the campervan gas regulations below.
Moreover, we have taken out the relevant information for campervans and put it into easy to absorb chunks.
Be aware, these notes are NOT direct quotes from the regulations; they have been reworded, but they still contain the relevant information.
Please refer to the BS EN 1949:2021 campervan gas regulations for the exact wording.
- The gas system must be tested to 5x the working pressure using a monometer (air pressure tester). So, the testing pressure for campervans (30 mbar) systems will be 150 mbar.
- A maximum pressure loss of 5 mbar is acceptable.
- All isolation valves should be open and all appliances turned off to ensure the entire system is tested.
- Test procedure
- Pressurise the gas system to 150 mbar
- Leave it for 5 minutes so the air temperature evens out (the temperature will alter the state of the air in the pipes).
- After another 5 minutes, compare the reading. The maximum pressure drop is 10 mbar; anything more and further investigation is required.
- The high-pressure filling and regulator hoses can be tested using leak detection spray at working pressure. Bubbles will form around the joint if there is a leak. There should be no leaks within 30 seconds of applying.
- Gas cylinders must be stored in a sealed compartment from the living space.
- A maximum of 2 cylinders of not more than 11kg each.
- The compartment must have a 50mm upstand at low level, so the door must not go to the floor. This is to ensure any leaked gas is contained.
- The cylinder(s) must be upright and fixed inside the compartment at high and low levels using a cylinder base and/or straps.
- All methods for securing the cylinders must be undoable without using a tool.
- You must be able to replace the LPG cylinders without disturbing the LPG installation and equipment.
- The cylinder position must not obscure the regulator, isolation valves or drop-out vents.
- The cylinder must be a safe distance from the vehicle’s exhaust system. The exhaust system should be no closer than 250mm when viewed from above and at least 300mm from underneath (outside) the vehicle. Alternatively, you can use a thermal heat shield that is not smaller than 25mm and maintains the compartment ventilation. The exhaust can cause heat through the floor and into the cylinder, increasing the pressure inside.
- Cables can be routed through the compartment, but there must be no exposed joints in the cable. Additionally, there must be no joins in conduit or trunking that route through the compartment.
- Gas supply control can use ELV (extra low voltage) wiring only.
- Any holes in the compartment, except for ventilation holes, must be sealed.
- Cylinder compartments can be accessible from inside the living space as long as they are sealed when closed to ensure no gas can leak into the camper.
Cylinder Compartment Ventilation
- For low-level ventilation only – The free area must be equivalent to 2% of the floor area of the compartment. A typical 50mm drop-out vent will provide 800mm² of free area.
- For high and low-level ventilation – The free area must be equivalent to 1% of the floor area of the compartment.
- A cylinder less than 7kg can use a 20mm drop-out vent (internal access compartment only).
Working Pressure And Regulation
- The fixed working pressure of campervan gas systems must be 30 mbar. The maximum flow rate for a 30 mbar regulator is 1.5kg/hr.
- Pressure regulators can be fitted directly to the cylinder, wall-mounted or slide-out tray. Also, they must be installed inside the compartment with the cylinder.
- The maximum length of high-pressure hoses is 400mm and should be routed to avoid stress on the joints. High-pressure hoses are used between the filling point to the cylinder and the cylinder to the regulator.
- The gas system must have clear markings of the pressure in the system. Typically, regulators have a sticker on them stating their pressure.
- High-pressure cylinder hoses must be clearly marked with their pressure rating (high-pressure LPG), colour-coded, and tested for LPG resistance.
- Replace any hose that’s damaged or showing signs of wear, stiffness, or cracking.
- Rubber hoses should be replaced every 5-10 years.
- The gas pipe between the regulator and the appliances must be rigid and made from copper or steel.
- All fixed appliances must be connected to rigid pipework. A continuous rigid pipe from the regulator to the appliance is acceptable.
- A flexible hose can be used for non-fixed appliances, e.g. a camping stove connected to a gas bottle that can be stored in a cupboard.
- This flexible hose must be less than 750mm in length.
- A shut-off valve must be installed before the start of the hose.
- The flexible hose must meet current LPG standards.
- It must be accessible for inspection so it cannot be routed behind cupboards or areas where it’s concealed, like under floors.
- Replace a flexible hose that’s damaged or showing signs of wear, stiffness, or cracking.
- Flexible hoses should be replaced every 5-10 years.
Gas Pipe Fittings
- Campervan gas pipes must be made from copper, steel or stainless steel and protected from corrosion where necessary. External pipes require a plastic coating to protect them from corrosion.
- Plastic pipe fittings must not be used.
- Permitted gas pipe fittings are cutting ring type, capillary, flare, compression and threaded fitting for nozzle.
- PTFE tape must be used on threaded fittings.
- PTFE tape must not be used on compression fittings. The thread does not seal a compression fitting, so applying PTFE tape could cause a leak.
- LPG pipes must be kept clear of electrical cables and components where possible. Alternatively, the minimum space between them in a parallel path is 30mm and 10mm anywhere they cross.
- Pipework and fittings must be installed so they’re accessible for testing and maintenance purposes.
- There must be no undue strain on the system, especially at joints, as they’re the weak points.
- Pipework and fittings must be protected against mechanical damage by installing them in a safe location and protecting them from vibration or user damage.
- Plug-in gas outlets must be installed outside the vehicle, be protected from road dirt and water, not contain any electrical connections and be labelled ‘LPG outlet only’.
- Copper pipework must be clipped to the surface with a maximum distance of 500mm between each clip. Whereas steel and stainless steel pipework require a maximum distance of 1 metre. Put as many clips as necessary for it to be secure.
Rubber coated metal clips should be used as they’re strong and won’t damage the pipework.
Shut Off Valves And Isolation
- All pipe joints, hose connections, valves and isolators must be easily accessible and identifiable.
- Each appliance must have a gas shut-off valve for isolation. The shut-off valve of the cylinder/tank can be used if a single appliance is installed.
- The shut-off valve must be clearly labelled as ‘gas’ and the appliance it controls. Typically, the handle colour for gas fittings is yellow.
- It must be obvious what’s on/off. Typically, on is when the handle is in line with the valve and off is when it’s at a right angle to it.
- A safety closing device (excess flow valves (EFV) or crash sensor activation valves (CS)) must be installed on appliances that will be used while the vehicle is in motion to prevent the uncontrolled release of LPG in an accident.
- If an over-pressure relief valve is utilised, it should release the gas into the cylinder/tank compartment or outside the vehicle.
- Shut-off valves and isolators must be positioned so they’re protected from road debris and dirt. Alternatively, a cover must be used as protection.
- Must be suitable for use in a campervan and have relevant instructions.
- Cookers and hobs must have secure burner caps.
- LPG appliances must be of the room-sealed type. So, the combustion (inlet) air must come from outside, and the exhaust (outlet) must vent outside. They must not use air from inside the vehicle for combustion.
- Space heaters have two air ducts routed to outside the vehicle.
- 3-way fridges have exterior side vents in the vehicle.
- Space heating must be provided by room-sealed appliances.
- Plug-in gas sockets are for external gas appliances only.
- Non-fixed/portable cooking appliances that need to be stored whilst driving:
- Must have a shut-off valve positioned before the flexible hose to the appliance;
- The flexible hose must:
- Be accessible. Therefore, it can’t be installed under floors, above ceilings or behind walls.
- Be less than 750mm in length.
- Not be touching hot surfaces liable to damage the hose.
- Be protected from stress and damage.
- If the appliance incorporates a plug-in socket for disconnection. The fitting must be able to close automatically when the appliance is disconnected.
Flue Terminals And Locations
- Flue pipes and accessories must be suitable for their purpose and appliance. Also, they must be installed as per manufacturer instructions.
- The entire flue system must be accessible for periodic inspections. Using a tool to access the flue is acceptable.
- A flue outlet must be at least 500mm from the gas filling point.
- A wall or roof flue outlet cannot be directly underneath or within 300mm of an opening window or vent. This prevents flue gases from being drawn into the vehicle. However, the flue must be installed underneath an opening window. In that case, an automatic shut-off valve must be installed to turn off the appliance when the window is open.
- Flexible flue pipes must be continuous and contained inside an air duct.
- Campervan flues must be secured to ensure they won’t move or come loose while the vehicle is in transit.
- Suppose the vehicle has a flat underside with chassis members (e.g. Luton vans). In that case, drop-out vents and the flue outlet must not be in the same ‘channel’ because flue gases could collect and enter the vehicle.
Installation Of LPG Tanks/Cylinders
- Permanently fitted gas tanks/cylinders must have an auto cut-off of 80% so they can’t be overfilled.
- They must also have a manual indicator, pressure release valve and overflow regulator.
- The tank/cylinder and its components must be fitted so that only the gas is extracted. Therefore, cylinders cannot be on their side, and the regulator must be fitted above the tank/cylinder. Otherwise, liquid may get drawn from the tank/cylinder.
- A warning label must be installed close to the tank/cylinder stating, ‘All appliances are to be manually isolated before refuelling the cylinder’.
- The tank filling point must be installed outside the vehicle and at least 500mm from a vent, opening window and flue outlet.
- A label stating that ‘all gas appliances must be turned off in case of refuelling (LPG, diesel and petrol)’ must be inside the vehicle where it’s easily seen.
- A ‘Close cylinder/tank during motion’ label is required near the tank/cylinder for appliances not used while the vehicle is in motion.
- Shut-off valves must be clearly labelled to quickly identify what they control.
- External plug-in outlets must be marked with ‘LPG outlet only’.
Slide Out Tray
- A slide-out tray can incorporate multiple appliances. Each appliance must have its own shut-off valve.
- One flexible hose must connect the LPG appliance/canisters on the slide-out to the vehicle LPG installation.
- The hose assembly must be less than 750mm and protected from stress and damage.
- The regulator must be mounted to the cylinder, wall of the compartment or on the slide-out tray.
- Before the hose assembly:
- an excess flow device must be installed;
- a shut-off valve must be installed no more than 500mm from where the flexible hose meets the solid pipe.
- Metallic gas pipes must not be used as a bonding conductor. Only a suitable cable should be used for bonding conductors.
- Metal gas pipes should be connected to the main earthing terminal with a “protective bonding conductor.” An earth cable must connect the gas pipe, using a bonding clamp, to the main earthing terminal, usually the 230v fuseboard earth busbar in campervans.
- The minimum cable cross-sectional area for copper pipework less than 35mm² is 10mm².
