Gas meter ventilation

All I can see within BS 6400 2:2018 regards ventilation are

a) if fitted in a meter housing, the housing requires 2% by area ventilation if fitted above ground, or 6% by area if fitted below ground

and

b) as part of the risk assessment for the work, to "conform there is adequate ventilation in the work area for the proposed activities"

which doesn't apply, as no meter box

I'll open the window during any soldering.

That corresponds with what I thought. Maybe it's a standard paragraph in all their quotes.

Thanks

Well I've never heard such a thing. If everyone around here had to have that, it would be daft. So when they fit dual fuel smart meters do they refuse cos it in te same cupboard. I have no gas and when I did I'd smell a rat if I could smell gas from a meter. Brian

I expect that in many cases what was allowed years ago (and continues to be accepted for meter replacement) is no longer allowed for new connections.

However Mr Burns has confirmed what I surmised, that it applies to meter boxes/housings, which I haven't got.

I reported a smell of gas from our meter. They were round amazingly quickly...

The guy told me that they used goatskin bellows to measure the volume, and over time they become impregnated with the smell of gas, and that would be what it was.

_After_ he'd done a leak test!

Does that mean that vegans can't have gas heating?

Scottish Gas Networks have replied to clarify:

The final say on ventilation would be confirmed by the gas supplier/shipper you appoint to fit the meter. Generally ventilation to the outside atmosphere is sufficient.

Owain

You have to have ventilation "to prevent an accumulation of gas" in the event of a leak.(and possible explosion)

Meters are no longer fitted indoors but in an outdoor ventilated enclosure for this reason.

Go and look at what neighbours in a similar situation to you have.

They have indoor meters.

Yes, they work to a maximum of one hour to respond to a notification of a potential leak.

I suspect he was pulling your leg or acting the goat :-)

They certainly used to use leather bellows. I would expect that that has long gone though.

Don't always trust them if they say there is no leak though. My parents installed their own gas central heating and fires in 1972. The gas board came and inspected it and tested for leaks (using compressed air IIRC) and then connected it. In the '80s we could smell gas. We called them round three times and they could find no leaks, but we could still smell it. Eventully we found the leak with soap and water - it was from their connection between the regulator and the meter!

Or just kidding.

I blame the nanny state.

You are a lot of silly billies :-)

Anyway, I've got the 10mm earthybondthingmy done and biscuits ready for Friday.
