Would be much better if they did. You may need to replace one or two screws with a slightly larger diameter. Those screws tend to slacken with the road vibrations causing the furniture to creak - not just on that panel!

Kutch says:
I wouldn't certify anyone else's work. Be them competent or not

I hear this a lot and there is only one explanation I can think of to justify it, and that is that GSR engineers don't like to lose the profit they would get if they supplied as well as installed a gas appliance.

I doubt that Kutch is actually telling the truth (without realising it), unless the only certification work he ever does is on gas appliances that he has supplied and installed. The implication therefore is that he has never gone to a gas boiler, or fire, or hob that he did not install. If you take your motorhome to the dealer you bought it from and have a habitation service done the engineer that does it will be certifying a gas installation that he / she did not install. Similarly the vast majority of British Gas engineers that go around servicing people's gas appliances are certifying thousands of systems that they did not install. The bottom line is that if you are competent to certify an installation it does not matter if you installed it or not. If you don't want to do it, the implication is that you are not certain that you are competent to look at what someone else has installed. There is no law or regulation against certifying someone else's installation, you simply apply the same rules and tests as if you had installed it yourself.
Personally I would be prepared to go and look at what someone else had installed, if I had an agreement firstly that the gas supply was not yet connected and that the fee would be £200 payable up front. Also that as soon as I saw a non compliant part I would cap off the supply and give the customer a quote to fix the fault (s). If the customer had connected the gas and it was dangerous there is a laid-down procedure which is to cap off the supply with the owner's permission. If they refuse to give permission you call Centrica who will be there in 15 minutes and cut off the gas permanently till the fault is fixed. They will shut off the service valve in the meter box and padlock it in position, and possibly remove the meter as well. This of course applies to residential and commercial premises rather than to motorhomes. I have seen British Gas's store of tampered meters where people even cut them open, bypass the metering system and reconnect the inlet to the outlet pipes and weld up the casing where they cut it!
The procedures for testing, certifying and for what to do if the installation is not correct, are all well documented and laid down, and are part of any GSR engineer's training and examining.

VERY interesting. As another serial modifier, I have been contemplating this issue for a while. On my Stanton (which was out of Warranty) I had long been concerned about the heat confined in this area where boiler electronics etc are housed. I was going to fit a ventilator, like the fridge vents, on the outside wall by cutting out a pocket in the wall opposite the boiler. (I have no fear, but my dear wife will be out when I do this! - see my thread on moving the Sargent EC500 unit which I did while she was visiting Hong Kong). This has three  advantages,
1. The vent cover can be removed easily without tools for access to the "important" bits of the boiler you sometimes have to get to.
2. This approach will provide more cooling for the boiler electronics and fuse.
3. If I do the job while Jean is out, it will be less traumatic. smile!

Of course, the fridge vent cover has a winter blanking plate to all but completely seal the new opening in colder weather in case it creates draughts from the vent under the wardrobe. This is no less weatherproof than the fridge ventilation, but might need the cover fitted for washing the motorhome - (whatever is your normal practice).

I have still to do this because I changed the Stanton to a Bourton last year and I have had all the mods I made to the Staton to catch up on. Also, I wanted to get to the factory and see where the timber struts are in that part of the wall so I can avoid them. Alternatively, does anyone know how to find small wooden "studs", as the builders call them, in a wall faced with aluminium?

As for doing a proper job to make it proof from water ingress, using the approved sealant and getting the hole size right will be important! I would add sealant around the new pocket edges, which will be Styrofoam and sealant tape around the inside of the new access panel after the vent cover is fitted and sealed, but then I am a belt and braces man.

The Boiler is fitted on a shelf above the wheel arch and the wall in this area will already be well supported. I'd be happy to hear your views on this. No electrical work, no gas work. it just feels like an easier option and by using the same vent covers as the fridge should look ok too (like it should be there!).

I found when I needed to reset the boiler, I used a mirror to see the reset button, I did buy a 8 inch marine type hatch that I was going add to the floor of the wardrobe directly over the reset button so I could reach down and reset if needed. Needless to say, still to do this

Ah, a man after my own heart Dennis! A fellow CSM (Compulsive Serial Modifier wave ). That sounds like a good idea, putting a vent on the outside wall. As for finding the timber frame in the wall you might be able to see it if you close one eye, squint with the other one and stand on one leg looking along the length of the body. There might be a bit of light deflection where the framework is. Alternatively get a stud locator from B&Q and wave it around the inside wall. Or just tap your knuckle along the inside wall and listen for a change in sound. You would need to have the vent right next to the boiler access panel of course. Don't worry about the Boss, she won't notice any change. I heard of a Suzuki motorbike chap who bought a new bike every year when the new models came out. As they were always the same blue and white his wife never noticed. I don't know how he hid the finances from her though.
One of my better modifications was to a Rapido kitchen sink drain. From the factory it was done in 25mm pipe and had seven 90 degree bends (to trap food in) on the way to the waste tank. When the plug was pulled, the water took ages to drain, and this was when new, not bunged up with bits of cauliflower. I removed the furniture - the kitchen was half way down the length of the van and the tank was right at the rear. I thought that's daft, instead of all these bends why didn't they use a straighter length? In plumbing, a 90 degree bend offers the same flow resistance as one metre of straight pipe. I ripped out whatever was in the way, just unscrewing things that could be screwed back, not sawing or cutting anything. I laid 32mm pipe, with a total of four 90 degree bends. The water now drained like the Niagra Falls with a very satisfying sluuuuurrrrp at the end. What puzzles me is why Rapido didn't do it like that in the factory? It would have been cheaper and taken less man-hours.

Oh. I also once changed a LHD Burstner to RHD and fitted a more powerful turbo engine at the same time - but that is another story, and it was a waste of time.

Thanks.
Of course, the inside wall in the boiler area is as inaccessible as the boiler (if not more so). My stud finder cannot see through the aluminium outer walls. I will be going to the factory in a few weeks time. I will try to find out then.

Ah. Before you go, download (if you haven't got it in the documentation that came with the vehicle) the Truma installation and servicing manual, show it to A/S and ask them why they don't install it in accordance with the manufacturer's instructions. If the discussion leads that way you can tell them that all the warranties should be void.

***WARNING***

In my post above, I advocated using a fridge vent to get access to the boiler. PLEASE DON'T TRY THIS!
it has been pointed out by the man who knows at Willersey service centre that the flue gas will be drawn into the van due to its proximity. This would be very dangerous- potentially deadly.

The only way is to use a toilet cassette door which will seal properly. I asked for a price for this work, but I fear it will be expensive.

Embarrassed - Dennis. confused3.

That's more or less what I used to provide easy access to the panel Dennis, with a sheet of (about 2mm) aluminium underneath to hermetically seal it.

I chickened out, so the hole in the van wall was cut by the dealer, and to miss the woodwork (only just!!!) he managed to drill a tiny pilot hole from inside. I then got a vent, probably from eBay, about a foot square to cover the hole. I cut the aluminium sheet to the same size, and sandwiched it between the van wall and the vent with plenty of bath sealant. Not Sikaflex or similar, because the whole point was to have something easy to remove if necessary.

The dealer had a spare toilet door which I could have had for nothing, but it was too big, and was going to be too much trouble to avoid the woodwork, and the substantial wiring loom in close proximity. I agree that it would be very expensive to have a toilet door fitted, as it's far from straightforward and fraught with danger!! I think Messrs A/S would deliberately scare you off with an exhorbitant price!!

I'll post a photo if you would like to see the outside wall of our van. It doesn't really look out of place at all, and has attracted only one curious comment in the several years since it was done.

Needless to say I've never needed to use it, but the peace of mind has been worth it, after the fuse had previously blown twice!

I have a separate modification to keep the panel cool(er) using a couple of computer fans. I could probably be persuaded to describe it if you are interested.

Yes, Well done! Project may be back on...

As the ASOC technical officer, I had access to the factory and took the opportunity to look at a part built Bourton. Above the wheel arch (which is where my boiler is, there is no woodwork in that part of the side wall in the space between the wardrobe walls, so access would (should) be danger free. Of course you are correct, sealing the access hole properly and disguising it with a fridge vent seems like the way to go. 

It will absolutely guarantee that I will no longer, ever, need access to the boiler - unless I am travelling without tools!

Best
Dennis

Pics to follow Dennis.

The cooling system is easy. The piccy shows the vents I used, and their position, so no need to explain. I couldn't get a matching colour, but the contrast doesn't jar with me. I just might try to find matching ones one day, but I doubt it!

One fan is set to suck air into the void, and it has a length of corrugated tubing taped in place so the sucked in cool air goes straight to the side wall where the panel is located.

The other fan blows out from the void into the van so that in the winter we get a small additional warm air supply. It's probably not necessary, but it looks better balanced with two vents, as you can see from the piccy.

Judging from the amount of heat that comes out, it appears to be quite effective. I just leave the fans permanently switched on all the time, whether we are using the heater or just the hot water, They are virtually silent, and are needed only when on hookup and using the heater on electric, so it works well.

I now see some confusion as to where Denis originally proposed a vent, and where I said it would be a good idea. I hope you all realised that I was proposing ventilating the living area wall of the boiler, not the outer body wall. The AS advice is correct, don't put a vent near the outside flue.
