I was told a long time ago by Aniston that you shouldn't use mortar as it could corroded flue

 

[ed209]

Ariston, bloody auto correct

 

[ed209]

There's got to more to this story I can't believe you would get it for that

 

[ed209]

I've seen loads sealed, un-sealed, foam, mortar, rock wall, kitchen roll, mastic, carrier bags but whatever was used the sealing collar was usually in place so nothing was going back in

I've seen wire wool used.

If it's expanded that far inside it may have done the same outside and partially blocked the flue?

I think Gas Safe just like to be seen as doing something. There's never been so much regulation across all trades...are standards of workmanship higher ??

worcester are the only manufacturer whos instruction/ Tech Bull ive seen saying you can seal externally with the rubber and expanding foam the inside to seal it. you need a six inch hole tho.

what they dont tell you is how to terminate the blow off back to the wall in flats without a ladder or scaff.

solder a 22mm cap in 15mm pipe and push through 28mm hole, make good in side.

As you probably know you can now buy the ones like you get with the Ideal logic +

how do you receive this mag? I am gsr along with my business partner, I have never received the mag, I don't think he has either, can he contact gas safe so we both get it?

 

[newcastle phill]

They just send it to numbtys.
You must be good.....


.....do you wanna borrow my copy

 

[combo]

When you sign up for GSR they give you the option of having the magazine sent to you via post or you accessing it via the Gas safe website. I opted for the latter but they still send me a copy anyway :smartass:. It's basically a few pages of prosecutions and then adverts....not worth my 400 odd quid registration fee, that's for sure.

I would like to know more about this one was it an old balanced flue replaced with a fanned flue and foamed ? I for one put the big rosette on the inside go outside fill with foam put weather collar on job done but this is in a 117mm cored hole if their saying I cant do that I,ll just have to go back to sand and cement

 

[newcastle phill]

Does anyone use expansion foam (recessed a bit) and finish with sand cement plug

 

[ed209]

Seems to me GSR and or the manufacturers should make a stand and tell us exactly how it should be done, as it seems a lot of us are unsure if the methods we are currently using are correct

I've never used foam and have always hated seeing it round a flue.

You won't find any manu saying it is ok to use foam and it looks like gas safe / HSE agree but as usual there will be more to this story than that.

Sand and cement or plaster inside. Rapid set is about £6 a bag and with 2 bags of sand you can build in 50 flues for a tenner. It sets in 15 minutes. A bag of multi finish is about £4. Open the bag and let it sit for a month or 2 and it will set in 5 minutes (sometimes before you can get it out of the bucket).

or if your very fast sand in with some old plaster

 

[tamz]

Sometimes it sets so fast i need to take the hammer to the trowel to get it out the bucket while i was mixing it.
A handful of finish in the compo makes it go off in 5 minutes too.
