Flue clamp screws

[mountainman]

I usually only write up flue clamps with no additional securing screws as NCS, but I've been told by an engineer that he understands them to be AR.

Any thoughts gang?

 

[Ermintrude]

Nope gas safe pulled an installation by a fitter who subsequently left me to fix all probs flue only got a ncs.

You mean the flues clipped but no screws in the elbows? That can be classed as ncs however it takes 30 seconds to correct

True, providing you have your power driver, self drilling screws and the flue isn't in the loft etc.

Not even a flue clip. Engineer wouldn't go back and address water leak round flue, custard called GS.

I would never put a screw on a flue joint I DID NOT PUT TOGETHER !!!

On multiple jointed flies I would agree but on the job which prompted my post the flue is a standard cut down 1m length connected to the boiler turret elbow.
But my question was; is the absence of screws, even if the flue is rigid and sound, NCS or AR?

 

[Ermintrude]

Ncs isn't it in dangerous situations bit?

 

[dancinplumba]

Does it require a screw ? What do MI's say

If flue is solid and presents no risk to persons or property, yet mi stipulated screws isn't it ncs as no danger? If no clips it's still ncs according to GSR !

 

[mountainman]

Mi's mention nothing.
So NCS it is then???

Had a gas safe visit last week he said its AR
It's because of a women that died in Wales his words not mine
No screws in a flue - AR
All Flue joints must be acess able if not AR as well

 

[mountainman]

So where is the TB or email from Gas Safe informing us.
What's the point in being registered if the registration body can't be bothered letting us know?

What about telescopic flues? The joint between the telescoping bits normally ends up in the brickwork.

Interesting one, but think this is reason why lots of installers don't point up just push rings on, when its not telescopic it's so u can see its not telescopic.

He checked 3 off are jobs last week and one of them there was no screws in the flue
It was a standard short flue going though a wall cemented in on both ends with no screw in it and we got warning from him under no uncertain terms let that happen again then he started the lecture on a women who died because of it and said all boilers with no screws are at risk
To be honest the guy was a bit of a knob but suppose he was just doing his job

 

[rab250]

If the mi say nothing then you are altering a flue aren't you . Viessmann say you dont screw their flues just clamp beneath the joint

 

[zeebeedee]

Gas safe dont seem to know there arse from there elbow. Ring up tomorrow they will say if its secure its ncs.

Arnt they all? Did mfr supply screws or provide info in literature? Baxi main and ideal are naughty boys! Valliant supply screws but their flues are so thin and flimsy just use silver foil - not for joints.... Make flue system out of foil.
Multi fit for duo GA had screws and turret screws- duo one now has same turret with locators but ne screws.

Don't I know it mate

Only manufactures that stipulate the flue joints must be screwed are classified as AR. A lot of the flues, the manufactures instructions do not state that screws must be used. Manufacture instruction is the correct way to install and if you have them then you don't go by the gas regs if they contradict. I had this issue a few weeks back, service engineer AR'd a Greenstar 24i JNR for not having screws in the flue clamps. Yet in the installation instructions it does not state that they are required. I rang technical and they conformed they are not required. Yet Vaillant say screws must be fitted. So go by the M.I.s and AR it if it's different, although I wouldn't necessarily AR a boiler fitted with screws if they weren't required.

 

[mountainman]

A common sense answer, cheers Arran!

This is another subject that should be plainly explained by Gas Safe, but we engineers are as always left in limbo.
Not good enough imo.
