Worcester Bosch flue self tapers?

[macka09]

Hi guys. Does anyone know where I can get hold of the self tapers for Worcester flue joints? Worcester want like £2.50 per screw. Just been to a local fixings place and they don’t have any. Any help would be great

Surely they’re to long for a flu?

I’m terrible mate. I’ve had my gas for near 5 years but always done wet Plumbing no gas. That’s why I question everything.

16mm
Doesn’t touch the inner flue

Are you sure? Without having a flue to hand that just seems to long. When I spoke to Worcester earlier they stated a size of 6.5 x 9.5mm

 

[ShaunCorbs]

100mm dia
60mm internal

gives 40mm space / 2 20mm either side + 1.5mm - 2mm for the alu

gives you around 21-22mm screw length before you hit anything in theory

I know that feeling, I was doing plumbing for about 11 years, held gas for same amount of time, but rarely touched it, certainly not appliances, not even heating. I still question stuff.

I sometimes think it would be less hassle to knock it all in the head and just stack shelves. Especially when you’re expected to do things that contravene regs. I’d rather not have the job.

I’ve often found myself thinking the same thing, but I’ve worked stacking shelves and checkout operation when I was an apprentice, it’s a bit mundane. I like the challenges of this job and having to sometimes think on your feet.

Guys, if an inner flue had been screwed or drilled how do we determine whether that’s happened or not without physically looking at it? Our firm recently replaced a flue due to the inner flue being screwed but trying to get an answers as to how they found that is like getting blood out of a stone.

 

[ShaunCorbs]

Will show up on your inlet / fresh air tests eg co2 and ppm

 

[macka09]

So that’s the only way of knowing without obviously taking it apart?

It could also show as part of a CO activation on an alarm, or also show signs of corrosion.

 

[Mastermixlee]

Taking it all apart is the only sure fire way of knowing as if they've screwed into the inner flue then it's likely the screw alone is enough to plug the hole and not affect combustion or air inlet tests.

That or a snake cam down the air inlet through the entire length of flue

 

[Scott_D]

Sometimes you can see along the inner flue through the test point or back looking back down from outside the house

The screwfix ones will be fine. If you want a slightly shorter screw, these are 3.9 x 11:
