Converting a heavy-duty bus/coach/truck into a motorhome

I agree with you, Christian06—depending on the brands (and thus the composite in the middle), the expansion coefficients can vary.

In any case, the solution isn't ideal.

I was wondering: for insulation, is this reflective film (made of PE sheets with foam interspersed, available in 3, 5, or 11 layers)—the process shown at http://www.campingcar-amateur.com/pag_site/isolation.htm—the way to go?

Otherwise I saw this kind of material at the agricultural fair, in an annex area showing everything for home insulation: ALP Isole and Europ Isole make this type of product, but you know how trade shows are—you don't get all the information.

Is this better than foam?

Is it useful to combine foam (large panels of 1.50x0.75) between the frame members, and the film near the false ceiling (and the same on the side walls)? You need to be careful to leave a 2cm air gap on each side of the film.

How do you insulate the floor of a bus?

Hi, can you tell me what the approximate timeframes are to get approval from the mining authority? I want to convert a coach into a home, and I'd like to import it from Belgium to convert it in France. Thanks!
FR François57 Regular ·
You'll need time for the conversion, plus an appointment beforehand to discuss with the DRIRE engineer about your setup—call them now, it's better. Otherwise you've got the plumber who needs to come by and Veritas to inspect everything: expect a 2-month wait before inspection, etc. ... plan for 6 months to a year overall.

Be careful with Belgium—they don't have vehicle safety inspections, so you could end up with a bad chassis like a forum member's VanHool. I'd recommend getting it inspected at the French vehicle inspection authority first, though it remains to be seen if that's possible.

Hello Patrick,

I'm currently finishing my business degree, and I want to sell fully renovated buses. However, I have absolutely no idea about the cost of this type of service. I'm sending you some attached photos of what I'd like my bus to look like. I really do want to commercialize this bus (it's not just a whim) because it's a genuine professional project. Can you send me your contact details so we can get in touch? Here are mine: 06 09 20 30 29 boublic@hotmail.com

Thanks in advance BOUBLI Cyril

Well, don't buy a Saviem!

Order directly from Vanhool (www.vanhool.nl) without seats or extras—just ask for an engine and chassis with the frame rails and uprights, exterior color, and carpet. It should cost around €100,000

Hello everyone! I've been following this community for a year now and wow!! Thank you all so much!! Thanks to you all, I've picked up a Scania S53 and I'm heading out to do humanitarian work in Eastern European countries. I'm really going to need some serious help from anyone willing to pitch in. So here it is. I've got a 1983 Scania S53 with 950,000 km. I want to convert it to heavy-duty status to do humanitarian aid work and organize shows in orphanages. We're carrying clothes and sound equipment to set up electronic music parties along the way. The bus has 950,000 km but it's always had amazing maintenance—I think it'll hold up to bring some sunshine to these kids. Thanks to everyone.

HOW LONG DOES IT TAKE TO GET A HEAVY-DUTY VEHICLE REGISTRATION?

WHAT PROBLEMS MIGHT I RUN INTO AT BORDERS AND WITH FERRIES IF I HAVE A BUS WITH HEAVY-DUTY REGISTRATION?

HOW DO I SET UP MY ELECTRICAL SYSTEM? I HAVE 3 SOLAR PANELS OF 100W AT 24V?

WHAT'S THE COST OF INSURANCE?

WHAT MECHANICAL MAINTENANCE SHOULD I PLAN FOR BEFORE AND DURING THE TRIP?

THANK YOU ALL—YOUR HELP WILL BE REALLY REALLY USEFUL BECAUSE ALL OF THIS IS TO HELP THE ORPHANS.
KA Kalifamily ·
Hi everyone,

I'm the owner of an S53 and I'm in the middle of converting it. Is it possible to put a wall between the driver's seat and the passenger seat? Of course, while respecting the door sizes that the regulations require, because I'd like to try opening a passage from the cab to the living space.

Thanks for your answers—the mining engineers and their paperwork are bugging me a bit.

Hi François 57, do you know where I can find the plans and measurements for the S53?

You need time for the conversion + a meet-up beforehand to discuss your setup with the DRIRE engineer. Call them now, that's better. Otherwise you've got the plumber who needs to come and Véritas to check everything: 2-month wait before the inspection, etc... plan for 6 months to a year.

Watch out with Belgium—they don't have technical inspection, so you could end up with a rotten chassis like that VanHool from a forum member. I'd suggest you get a mines inspection in France first, though we'll have to see if that's possible.

Hi everyone, we're new to the forum but have been following it since we bought our VANHOOL 815. We have a question that's bothering us: how can we insulate the windows if we don't have the manufacturer's permission—they specifically told us not to touch the structure?
http://pandree.skyblog.com
CA Cateludo ·
Hey, just to be clear, what I'm about to say is just my opinion and shouldn't be taken as gospel, but in my view the windows aren't structural elements. Replacing them with sheet metal, if done properly, shouldn't cause any problems, as long as you respect the emergency exit requirements. Which means: think your plan through carefully before you do this work.
Ca y est, c'est reparti !!!
PA Pandrée ·
Thanks cateludo. I think I'm going to call my manager and ask them the question. For now we've kept the front windows from stock because we don't have a driver's door (just in case!!!). Thanks again, I'll keep you posted. bye bye, pandrée

Hi, with my bus search keeping me busy, it's only now I can thank you for your advice on finding an FR1. But I've just bought one closer to home—I'm hoping I made the right choice! FR1 type E, year '87, 840,000 km, one owner, perfectly maintained, bodywork in very good condition, just needs a paint job. 6,000 euros all-in. The seller also has a PR 14 that's inexpensive and apparently in good condition.

Hi everyone, I'm sorry—I'm new here and didn't have the courage to read all 23 pages of this thread, so you may have already covered my question: Can you convert an articulated bus the same way you would a standard motorhome? Something like a Mercedes O405GN or Setra SG219 SL? You can find them everywhere on secondhand sites and from transport companies, but is it legal?

My dream, being an enthusiast and only 19 years old, is to buy an articulated bus and convert it into a motorhome. (! The greatest dreams are those of our youth! Plus I've got all the time in the world to work out the details and present my project! 😎) From what I've read on bus forums, it seems a Lyon-based engineer managed to convert an articulated bus, creating a loading ramp on the back of the trailer and space for a small car. But in my opinion that's still quite an exceptional achievement!

The thing is, the handling on motorways or fast roads might not be tolerated, even though once you remove the limiter an articulated bus easily reaches 100–110 km/h, and factory deliveries to transport companies happen on 4-lane highways.

Do you have any info or know of similar examples on this subject?

Best regards, A guy from Brest😉

45,000 euros—you've got to be joking!!

come on, some people are completely out of touch!!

for that price I'd buy a barn, two buses, and outfit them under the barn! !

Would anyone be interested in a 1992 609 D Heavy Truck, converted and certified for 9 people? See the classifieds section for used equipment. It's a bulletproof vehicle; the setup is really well designed so everyone has their own spot, day and night. We've outgrown it—our 6 kids are leaving the nest! Don't hesitate to reach out.
CA Cateludo ·
Okay, quick question for patrick26: Given my bathroom layout, I'd have liked to put just a small high opening, like 60x30. Am I allowed to do that, considering the nearest emergency exit is exactly 1.50m "as the crow flies" from my bathroom door? Good evening and thanks for your answer.😉
Ca y est, c'est reparti !!!
PA Patrick26 Veteran ·
The measurement is taken from handle to handle. The distance should not exceed 1.5 m.

otherwise, enlarge the window and position it less than 90 cm from the floor (if I'm not mistaken).

hoping that I've answered your expectations....

for info and for everyone else, my bus just came out of the paint shop! the bodywork is thus complete (rear opening, sheet metal welded in place of windows, etc), what's left for me is to install the windows, the holes were drilled before painting, reassemble the cargo hold doors that we'd taken apart to paint inside and out, reassemble the bumpers and put in place the new windshield and new rear lights and tint the windows with medium onyx. 2 short days of work and we'll tackle the interior installation which is almost ready in the garage....

for the electrical, a Sheiber installation with an inverter, 800Ah of batteries and a 3kW generator, so I've got the whole 220V installation behind a separation transformer that's in the inverter, and I'm not dealing with complications. cost of all the equipment, including the generator and batteries of 4800 euros and complete and permanent autonomy. (same setup as in big American RVs)

an additional 24V compressor at 8 bars will also be added to operate the louvered door that will be controlled from outside by a remote (like alarms) and a relay.

a few photos of the bus are attached.

GOOD EVENING TO ALL PATRICK26

Hello everyone I'm new here. Patrick26, you're doing an excellent job........well done! You all provide really interesting information.

So I'm interested in a double-decker coach for the living space (long stays and especially with mom, dad and two kids!) I've heard about Vanhool but the price!?!........ Could you recommend a model I can find that's not too expensive, doesn't use too much fuel, and can be converted? On the other hand, doesn't the height of double-decker coaches rule out a lot of routes in France and abroad, or is there still a way to go everywhere anyway? All information about double-decker coaches is welcome, no matter what!! I'm not picky ;-)

Thanks everyone
PA Patrick26 Veteran ·
Double-decker coaches, we've already talked about them in this forum....

each floor is less than 175 cm high! it doesn't fit under all the bridges! it uses more fuel, obviously, given the weight and wind resistance! that must be the issue for homologation (emergency exits on the first floor in closed rooms? jump out the window?). etc...

a 'normal' coach already represents almost 30 square meters of space! a large part of the world's population doesn't have that much space to live with their family. there's already plenty to make a very spacious setup!..... and it's doable!

now, if you want to go that route, Vanhool's double-decker buses are called Astromega (avoid the triple-axle ones that are over 12 m and won't be able to be downgraded to heavy-duty).

at €15,000, you'll find one that's already very worn! I know one for sale for around €2,000 to €50,000 and it's got very high mileage.

go check out the Vanhool website.

PATRICK26
LA Lavogadro ·
Ok Patrick You're right, we shouldn't aim too high. You're right. If you want, I'm still thinking about the choice. If it's not a double-decker bus, I'm thinking about the Renault S53 which isn't very expensive and apparently doesn't consume too much fuel (23L/100km I think on average) Length: 11.375m Width: 2.50m Height: 3.14m That's not bad already There are probably other buses that would work well (inexpensive, square shape, not too fuel-hungry) but I have to admit I don't know enough about them...

Once the bus passes inspection and changes category, do I still need a heavy vehicle or public transport license to drive it?

How much does everything cost approximately, and once the bus is converted, the category change, inspections, registration change, etc.?

What's the most advantageous category in terms of insurance, tax obligations, license, inspection, etc.?

As you can see, I'm currently studying the feasibility of my project. If it doesn't go over budget too much (time, money...), I'll go for it and make the whole family's dream come true!!! ;-) What joy to travel in your own home! Not having to pay for overpriced hotels that you're not necessarily happy with! Anyway...

Thanks for your answers, Patrick ++

Hi,

I'm new to the site and I'd like some information about a project I'm working on. I'm looking to buy a bus to convert into a motorhome for motorcycle competition. So there will be a motorhome section and a workshop area for working on and transporting the motorcycles.

We'll only be putting a few km on it per year and we're working with a small budget.

I have several questions that may already have been covered: Do I need a commercial/heavy-vehicle license (PL) or a coach license (TC)? Which model should I go for? Is there a DRIRE document for the conversion? And if so, where can I get it?

Thanks for your help and I'll keep you posted as things progress.
MR Mrkonn Regular ·
🙂Hey everyone, so when are those photos coming cateludo? For me I'm waiting until the end of the season to start the work😕

🙂Hey bastosyz450, You need a C permit (HGV). Check with your department's DRIRE for conversion plans For the bus, several of us have gone with Saviem/Renault (bus prices are really cheap, fuel consumption 20-30L per 100km)

Small correction - my bus is an S105R, not an S45

If I got anything wrong, let me know. 😉Cheers
PA Patrick26 Veteran ·
In my opinion, the best bases are VanHool and Volvo B10. A Renault Carrier would work just as well.

For the other questions, all the answers are in the 24 pages of posts!

Hey everyone

I use the forum a bit like a chat Question for patrick26

Once the bus has been through inspection and reclassified, do you still need a heavy vehicle license or public transport license to drive it?

Roughly how much would it cost all-in for the category change, inspections, registration change, etc., once the bus is converted?

What's the most advantageous category in terms of insurance, tax obligations, license requirements, inspections, etc.?

Hello,

I just bought a 1977 Setra.

I've thoroughly read the 24-page thread looking for info on vehicle registration. Ours has been registered as VASP since June 2005.

I'm hesitant about downgrading it to collection status to avoid having to present it every year. The collection category suits my intended use, but I can't figure out how feasible it would be to re-register it as VASP later if needed, for travel or resale.

See you soon, thanks

Hey,

Don't do it, buddy – I speak from experience. I've been into old cars, bikes, motorcycles, tractors...etc for 20 years and founded a club in '89. Switching a standard registration to a classic registration is IRREVERSIBLE!!! 🙁 You're stuck as a classic for life! As of 01/01/2008, classic vehicles will have to pass a technical inspection every 5 years 😄😄😄 Now I laugh – I've been saying this to my buddies for 15 years, the ones who switched to classic to skip the inspection, and now for many it's scrap because a vehicle not kept in good condition (play in the ball joints, track rods, shock absorbers, brakes...etc) for over 10 years becomes a real headache. No more maintenance, no more spare parts sales, so no more parts manufacturing 🙁

You should know that originally, classic registrations were intended solely to allow you to re-register a vehicle that had been officially written off but later rebuilt. That's why you're limited to driving in departments bordering your registration department with the possibility of outings (max 12/year) that are monitored and only for car meets, rallies, exhibitions...etc plus you have to buy the permit logbook 🤪

In short, you're already lucky to be in VASP, stay there 😉 – a classic registration will ONLY bring you headaches (for example: banned from driving on Route 23 in Sarthe during the Le Mans 24 Hours)

PS: A vehicle with a standard registration can be insured as a classic. I personally have 28 vehicles with standard registration insured as classics. 😉

That's all folks! 😛 GX47

Thanks so much for the advice. As for me, I'm still hesitating because starting January 1st, the vehicle can be driven throughout the entire national territory, and technical inspections only need to be done every 5 years.

That said, I'm torn because I do see the waste involved in downgrading a vehicle that's in good condition.
GX GX47 Regular ·
Not to mention the restrictions coming down the line. And you're right: National Territory For now we're not talking about it — gotta attract customers — we're in a country of (over)consumption. The goal is to control the road network (at one point they were thinking about having ONLY vehicles on 'leasing') old vehicles --> to the scrapyard, collector vehicles --> to museums!

Just by the way: Nikoko almost got us to scrap our Jeeps and GMCs equipped with a mount or turret (even empty) or fitted with recovery equipment. Our club presidents fought and obtained clear language in the law exempting vehicles more than 30 years old (first registration) and more than 20 years old (last registration). (PS All Jeeps in their original condition have a gun rack bolted to the windshield --> was that taken into account???)

THE BUS LEAVES THE GARAGE TOMORROW MORNING!

it's painted, the storage doors are back in place, the dashboard's been taken apart and repainted too (might as well!), and even the trim rings are on!

all that's left is the windshield (the installers arrive at 9am tomorrow), and then back to my parking spot to tackle the interior.

it all needs to be done by the end of May to give Veritas and the mining authority time to get me the certifications before the big test beginning in August.

Hi Patrick,

Congrats, nice work, great success (especially the tough negotiations) and lovely decor.🙂😉 Glad you pulled it off where I didn't have the guts to push through. When I see your rear opening, it gives me a bit of the jitters... it was, as you know, my original project, so to save time and especially to make sure I got what I wanted, I took advice from our mutual friend at Heuliez and settled on the GX47 (I was lucky enough to have already found one and put a deposit on it). As he told me: "it'll always be possible to expand the opening later" (we've already agreed on a bodywork shop). If I manage it, I'll post a photo when I get it. Anyway, at least now thanks to you the door's open.😎 You deserve the credit for that. Okay, as for building a statue in your honor, that'll have to wait a bit, first I'll see if we can't rename the Champs Elysées😏 Okay I'm out😏

But first, what'll your category end up being? I wanted "truck lodging/equipment" (I was already off to a bad start😄) GX47

Hi everyone and thanks for your tips,

Being myself too – who would've thought!? – planning to convert a bus (actually two, with my brother) for an Asian adventure, I naturally read through this helpful discussion thoroughly. However, unless I'm mistaken, I didn't find an answer to this question:

What are the minimum modifications needed to meet an unspecified RTI type? Basically, just enough to be classified as a commercial vehicle and be able to drive (and insure) the bus with a Class C license before finishing the conversion.

Additional questions:

Patrick26, in one of your posts you mention three types: nspc, vasp nonsp, vasp autocaravane; could you clarify that please, especially since initially it would be the nspc classification that interests me.

Sputnik, you said you waited 2 years before getting your vasp qualification; what was your bus's status (gorgeous machine, by the way!) during that time?

Also, what do you all think about the idea of an RTI with a 'deepened cabin' (8 seats, a partition and that's it) with the option of later cutting a door in the mandatory partition (or even removing it entirely)? Does anyone know the specifications for that partition?

Obviously I could ask these questions directly to the DRIRE, but I tend to think that like with insurance, the less they know the better... I wouldn't want, having revealed my future plans, to end up being denied an intermediate RTI. If you think I'm worrying over nothing, let me know.

By the way, we both already live in a truck (508 and LT35) and we're looking for a patch of land to base ourselves while we do the bus conversions: (Gironde, Dordogne, Lot et Garonne or Charentes Maritimes) (various trades possible: truck, building skills – carpentry, roofing, stonework, masonry – you name it!?) if anyone knows of anything in the area, we're all ears.

Important note: we have some solid leads but don't have the buses yet, so if anyone has tips in the region...

There you have it, thanks in advance, and best of luck to everyone.

Hello everyone, I've just joined you for a bus-to-camper conversion project. 1st question: after buying the bus, do you need to reclassify it as a heavy vehicle, true or false? What's the procedure? Thanks for your answer

I'm converting a DAF / HEULIEZ MB205 bus.

Cheaper and roomier than a car, the paperwork (in France) isn't insurmountable for certification.

I'm ready to help anyone who wants to get started on this type of project. Those who know should help those who want to do....
PI Pirou62 ·
Can you give me some details about the bus for sale?
FR François57 Regular ·
Indeed, you'll need to downgrade the vehicle classification or maintain more than 9 seats including the driver (but either way you'll need approval from your regional DRIRE), and as I'm planning to do, downgrade it fairly quickly, like Kersode is planning to do as well, by creating a rear partition with a door to access the emergency exit. That works out to about 85€ for the DRIRE inspection plus the registration change, so around 100€ total to be safe and able to drive it with a Class C license. Personally I've gotten questions like "yeah but why don't you just go straight for a campervan instead? but that's going to cost you an inspection, oh wow..." Anyway, you're set and you've got the Heavy Vehicle insurance (full-coverage insurance is crazy expensive).

Another advantage: as soon as your conversion is decent and usable, you can already use it as a campervan. However, be careful with the final installation (gas, fuel, ventilation, emergency exits...) — it's subject to standard NF S 56-200.

By the way, a question on this topic:

Can someone share the complete NF S 56-200 standard with me? Thanks
LO Loranhoutan ·
Here's the standard in question, happy reading, good luck

The NF S 56-200 Standard

Caravans and Motorhomes (Camper Vans) French standard approved by decision of the Director General of AFNOR on June 20, 1987 to take effect on July 20, 1987.

As of the date of publication of this standard, it is in partial accordance with ongoing ISO work, with certain liquefied petroleum gas installation conditions being specific.

This standard aims to reduce the risks of fire and asphyxiation in caravans and motorhomes by establishing minimum requirements regarding emergency exits, ventilation, risk zones surrounding household appliances, as well as the installation and use of liquefied petroleum gas and liquid fuels.

International Technical Thesaurus: accident prevention, fire protection, caravan, safety rules, requirements, emergency exits, ventilation, gas installation, liquid fuel installation. Prevention of fire and asphyxiation hazards.

1 PURPOSE

This standard specifies the main safety requirements that caravans must meet in order to prevent fire hazards, fire spread in the event of fire, as well as asphyxiation hazards. Note: electrical installation is covered by a separate standard (NF S 56-201).

2 SCOPE OF APPLICATION

This standard applies to caravans, rigid foldable caravans, motorhomes (1) and converted vans (1) unless otherwise specified.

3 DEFINITIONS

3.1 Caravan. A habitable vehicle, towed, which meets the requirements for construction and use of road vehicles.

3.2 Foldable caravan. A caravan of rigid construction, or otherwise, whose structural dimensions can be reduced.

3.3 Motorhome (1). A motor vehicle equipped, occasionally or permanently, with a habitable unit, or a habitable motor vehicle, which meets the requirements for construction and use of road vehicles.

Note: the vehicle is either adapted from a series-produced vehicle or designed and built on an existing chassis with or without a driver's cab. The habitable area may be fixed or removable.

3.4 Converted van (1). A motor vehicle whose equipment and layout allow for habitation.

4 REFERENCES

5 EMERGENCY EXITS

5.1 For caravans and foldable caravans, each habitable compartment, separated otherwise than by a non-lockable curtain, must be equipped with an emergency exit giving direct access outside the caravan.

Sanitary compartments equipped in the rooms defined in Chapter 3 must be equipped with an emergency exit when evacuation requires passing in front of a risk zone (heating appliance, cooking appliance), except when their own door is less than 1.50m, clear of any obstruction, from the caravan door. Distance measured from handle to handle, doors being closed.

5.2 The openings constituting emergency exits (1) must have the following minimum areas and dimensions:

· For caravans and foldable caravans, and sanitary compartments of motorhomes and converted vans: minimum clear opening of 0.20m and 0.45m in their smallest dimensions.

· For children's bedrooms separated with stacked beds: minimum clear opening of 0.20m and 0.35m in their smallest dimensions. Additionally, the lateral anti-fall protection of the upper bunk must provide a minimum passage of 0.45m to facilitate evacuation.

The inner free edge of openings constituting emergency exits must not be at a height greater than 0.95m from the floor.

5.3 For caravans and foldable caravans, window or emergency exit panels (1) opening by projection must be able to open to at least 70° and must remain open by automatic locking. Similarly, window or emergency exit panels opening by vertical sliding must be able to remain open by automatic locking.

5.4 Exterior doors must not open inward. The closure must be such that it must be impossible to close the door without being able to open it immediately from inside.

5.5 The opening mechanism of interior doors must be able to be operated from both sides; in the case of a lever handle, opening must be achieved by pressing downward; furthermore, in the case of a door with a lock, an emergency unlocking system must be provided from the other side.

(1) For motorhomes and converted vans, refer to texts applicable under road traffic regulations in which other dimensions are prescribed for emergency exits.

6 VENTILATION - AERATION

· robinet operation and disassembly are easy.

· room ventilation openings cannot be blocked.

If bottles are placed in an enclosed housing, it must be ventilated by openings in the upper and lower parts with a minimum section of 50 cm² each.

(7) In cold weather, the vapor pressure of butane is too low to ensure proper appliance operation.

8.1.2.3 Outside the room

Bottles may be installed either in the open air or inside a shelter, recessed or not into the room.

If they are in the open air, the location provided for their installation must be located more than 0.50 m from doors and windows of the room or any aeration opening.

If they are in a shelter, it must be designed such that bottle and robinet operation is convenient. The shelter must be ventilated by openings in the upper and lower parts with a minimum section of 50 cm² each and must not contain any apparatus capable of producing flames, incandescence or sparks, or any opening communicating with the inside of the room. Very low voltage cables passing through this shelter must be protected or arranged so as not to be damaged by bottle manipulations. The opening(s) located in the upper part of the chest must be at most 10cm below the robinet of the container(s) (5).

Ventilation openings must be located more than 0.50 m from doors and opening windows of the room or any aeration opening thereof. This distance is measured according to the actual path of the vapor from the point of vapor emission.

8.1.3 Equipment and connection of stations

Bottles supplying appliances must be equipped with accessories and safety devices adapted to each type of supply.

Based on the number of appliances used, the location and composition of the supply station, it must necessarily include the equipment indicated in Annex A.

In the case of multiple appliance supply, the station must provide the flow and pressure necessary for the normal operation of all appliances.

Valves and pressure reduction devices located outside must be protected from impacts and weather (for example, protected by a cover).

8.1.4 Supply pipework 8.1.4.1 Usable pipework

Fixed supply pipework for appliances must be metallic (steel, copper or brass exclusively) and provide all guarantees of tightness, resistance to mechanical, physical, chemical or electrolytic actions.

The various elements of pipework must be assembled by methods guaranteeing good tightness and good resistance. The use of soft soldering in particular (fusion temperature of filler metal less than 450°C) is prohibited.

Flexible connecting hoses (flexible loops) are intended to connect either a bottle to an accessory, or a bottle accessory to fixed pipework.

Flexible hoses may only be used to individually connect fixed pipework or a container accessory to an appliance other than a fixed heating appliance or hot water production appliance.

The end of the fixed pipework or accessory to which the flexible connection hose to appliances is connected must be placed inside the room and arranged such that the length of the flexible hose does not exceed 1.50m and does not hinder room occupants.

5.1.4.2 Installation of pipework

The entire pipework system must be installed by experienced personnel. Pipework must be properly fixed (approximately one fixing per 0.50 m for copper and 1 m for steel) and protected wherever it risks undergoing impacts or friction and, in particular, must be mechanically protected when fixed under the floor.

It may be placed under skirting boards, casings or double-wall partitions, provided that access is possible, if necessary by simple disassembly of these skirting boards, casings or walls and the volume thus created is in direct communication with the atmosphere at both ends. Pipework arranged inside these skirting boards, casings or partitions must not include any screwed element or fitting.

Pipework must not be in direct contact with metal parts of the room structure and its support or in contact with metal pipes (hot or cold water, etc.). The minimum space between gas pipework and accessories and electrical conduits must be:

· 3 cm in parallel runs.

· 1cm at crossings.

This distance is increased to 0.10 m between gas pipework and accessories and the vehicle exhaust pipe.

Where pipework enters the room, the annular space between the wall and the pipe must be sealed by means of a flexible joint ensuring mechanical protection of the tube.

If pipework enters the room through the floor, it must also be protected by a rigid sheath extending the floor on the upper part by at least 5 cm. This protective sheath must have an internal diameter at least 1cm greater than the external diameter of the pipe it protects. The inner ends must be deburred so as not to damage the pipework.

In the case where pipework is awaiting a future appliance, its end (even if including a robinet or accessory) must be sealed by means of a threaded, sealed cap.

8.1.4.3 Pipework tightness check

After installation and after any modification of the installation (1), fixed butane and propane pipework must, under the responsibility of the manufacturer or installer, undergo a tightness test performed with air or preferably with an inert gas (nitrogen).

The test may be performed using the service gas (butane or propane). If performed with air the control robinet or pressure reducer-interrupter with incorporated robinet must remain accessible when the supplied appliance is in place.

The control robinet may be that of the container if it is placed directly nearby and supplies only a single appliance.

When the fixed pipework connection to the appliance is made by flexible hose, the control robinet or pressure reducer-interrupter with incorporated robinet must be:

· arranged such that the condition of the flexible hose can be verified.

· arranged such that the flexible hose fitting is easy.

· fixed such that its repeated operation does not risk damaging the pipework.

The test of pipework from the butane or propane container(s) to the final pressure reduction, is performed under a pressure of 3 bars (controlled by a metal pressure gauge with 0.1 bar precision). The control robinets arranged upstream of the appliances being in the closed position.

For pipework from final pressure reduction to appliances, tightness tests are performed at double the service pressure, with a minimum of 150 mbar (controlled by liquid column manometer).

When test pressure is stabilized, no leaks must be detected in the following 5 minutes.

Tests are considered satisfactory if investigation of all joints, fittings and welds by means of a foaming solution reveals no leaks and if gas can pass normally through all parts of the pipework.

The search for gas leaks using flame is strictly prohibited.

8.1.6 Verification of appliance operation

The installer must ensure that appliances installed by them in accordance with the requirements of paragraph 7 are suitable for the pressure and gas used. Verification of the operation of appliances must also be performed.

8.2 General Instructions applicable to users 8.2.1 Installation use instructions

· extinction or failure to ignite.

· elevation of carbon monoxide content of the atmosphere above 100 vpm (0.01 %).

Connection of pipework to appliances

Fixed pipework must be fitted, for each appliance, with an independent shut-off robinet located upstream of it in immediate proximity or, if the connection is made by flexible hose, immediately upstream of it, or the pressure reducer.

(7) An intervention not affecting the system's tightness, such as fitting a cap after removing an appliance for example, is not considered a modification of the installation.

8.2.4 Reserve containers

Regardless of installation mode, only one non-connected butane container with capacity greater than 10 liters or one non-connected propane container with capacity less than or equal to 6.5 liters may be stored in the room.

Any transfer of butane or propane from one container to another is prohibited.

8.2.5 Container connection

Connection and disconnection of butane or propane containers must be done in the absence of flames or sparks after verification of closure of the robnets of these containers. If containers are on the drawbar of a mobile room the vehicle engine must be stopped.

Before connection or disconnection of container(s) located outside, in shelter or not, it is verified that any opening into the room and located less than 1m away is well closed.

The presence and good condition of the tightness joint must be verified before connecting a container to the installation.

8.2.6 Flexible hoses

Flexible hoses must be replaced as soon as their condition requires and in any case before the expiry date.

Only flexible hoses complying with standard NF-GAZ Butane-propane NF D 38-101(1) may be used.

Their length must be sufficient to avoid any tension but also as short as possible and in any case never exceed 1.5 m.

Flexible hoses must be securely fastened at both ends and arranged to be neither reached by flames nor damaged by combustion gases, hot appliance parts or product overflow during cooking.

If necessary, they must be fixed, without constraint, at several points along their length to prevent damage from swinging caused by room movement. Their replacement must however remain easy and they must remain accessible over their entire length.

It is forbidden to use a flexible hose to connect a bottle station located outside to pipework or an appliance installed inside the room.

8.2.7 Appliance adjustment

It is forbidden to modify appliance adjustment as well as the bore of injectors and burners or to modify their shape, outside cases provided in the installation instructions supplied with these appliances.

8.2.8 Installation verification

The installation must be verified every year or at least before each return to service.

This verification will particularly focus on the condition of pipes (flexible and rigid), the securing of containers and connections to appliances.

When there is suspicion of leakage, the use of appliances or other objects capable of producing flames, incandescence or sparks (lighter, gas igniter, cigarette, etc.) is forbidden.

To search for leaks, appropriate means must be used such as foaming liquid for example. The search for leaks using flame is strictly prohibited.

(1) Hoses complying with this standard bear the following indication: NF- GAZ Butane-Propane followed by the expiry date.
