Is this an isolation valve?

[TNDU]

On one side of a cabinet is this valve, pictured, which looks like an isolation valve ( /elbow) and the other side is the pipe connecting to it, which then leads to the gas fire.

There is gas supply to the fire so if this is the isolation valve, it is in the open position.

I can't work out why the straightline across the valve, indicated with the red arrow, where you can insert your flat screwdriver head is in a horizontal position rather than a vertical position? I would have thought that it should be in a vertical position to be open?

Looks like a restrictor elbow, so doesn't matter which orientation the screw is in.

I see, thank you.

So to restrict the gas flow, you turn that screw clockwise? And if you turn it clockwise fully, it would shut the gas off to the fire to allow servicing?

The only people that should be touching that is someone with GS registration.

No it won't.

 

[TNDU]

No it won't.

So it is only to regulate flow and can only reach a certain level of minimal flow. Thanks for the reply!

Please don't adjust it, you are only likely to create a gas leak.

Google it.

Google it.

I did google "restrictor elbow" when Stuckinarut stated that it looked like one. It seems to say that they are often found for gas fires to restrict the flow of gas to the fire, but it also stated that it is used to shut off the gas supply to allow the gas fire to be serviced, which seems to be inconsistent with the answers on this thread (confused)

If you watch one of the videos, it might help you understand how it works.

I'm afraid we are not allowed to give gas advice on this forum so cannot advise as to how it works nor advise how it should be used.

If I can give one piece of safety advice, please stay away from it. Manipulating any part of it it could create a dangerous gas leak. Whoever the GSR engineer is that will be in servicing the fire will know exactly what to do with it.
