Boiler AR??

[gaspastemania]

Have been helping a friend with a heating install today, boiler and rads upgrade. He was installing the boiler and i noticed he had screwed the boiler to a sheet of wood so he could get a fixing .Now my understanding of this is that its a potential fire risk so is AR situation, i have always used fireboard in these situations when securing a boiler against a possible flammable material to seperate from source.Made a casual comment about this and that he should refer to his viper , i know he wont as he is quite bullish at times but he's paying my wages on this job. Anyone think i am right and should pursue this or let him go as its his job .( kinda dont wanna rock the boat).

your 100% right he should have lined the wood with ellis board

 

[REDSAW]

back to the wallpaper question again though is it not?.

 

[Plucky]

Not always the case. Worcester have released a TB stating they can be mounted on ply or similar combustible surface.

Check with the MI's

At least a sheet of fire plaster board, I had to rip out an install some agency Lads did on a housing acsociation better homes upgrade, they had taken an old kitchen unit door that had been in the garden of the house and was like weetabix on the corners, screwed that to the wall, then hung the boiler 12 degrees out of plumb on that.

you need to tell us what specific boiler he fitted on timber then we can tell you if he or you know what they are doing, check the MI and it will confirm if the boiler needs to be fitted on a non combustible material or not

Btw ANY plasterboard (12.5mm) is suitable. It has a half hour rating, but as Redsaw said we have the wallpaper question. Worcesters in particular, with their plastic frame could hardly state the must be mounted on an incombustible wall. The frame would melt before the woodchip caught fire. Use your common sense and have a read of the particular MI's.

 

[gaspastemania]

Its a worcester gs 28i he has fitted, iknow that he can be quite a corner cutter which is why i mentioned it to him about possible fire risk,its up to him if he wants to check the MI's (i know he wont). As for the wallpaper question i have always either fitted fire board or removed any combustable material where the boiler will be directly fitted,was the way i was taught may be old school practice nowadays but better safe than sorry as they say !!!

 

[BLOD]

You could always give worcester a quick call to confirm it's ok mounted as it is.

got to go with redsaw my mates been doing it for yrs as what you suppose to do if it needs a good fixing also who foots the bill for you being fussy if you start adding money they will just go to someone else fire boards about £50 last time i looked plus you have a big round expantion vessal with water in it behind of the burner also most boilers allow you to have a cuboard round them in the kitchen and usually with 10mm or 20mm gap so to me theres no diffrence as being on a board which is much futher away from the wood than the cuboard

ellis boards are around £13,it all depends on what mi,s ask for

 

[REDSAW]

it gets absolutely ridiculous is some cases.
what about timber framed houses, cladded rooms for example.
if you put a piece of baco-foil behind the boiler mount the same as you do with wallpaper then this covers the combustible rule.
crazy.

and the modern ones dont get anywhere near as hot as the old wall mounted cast iron lumps

are you talking about the appliances or the fitters

 

[metaldust9]

point am trying to make is a peice of wood/board is no diffrent to having a cuboard round your boiler just the same fire risk

 

[gaspastemania]

We both had a look through the MI's today and it does state about refering to viper about combustable materials , either way its not my install and like has been stated ellis board is only £13 so wont do no harm either way .

the appliances,then again the old mans always overheating reckon its because he moves faster than the youngsters i reckon his high limit stats gone down
