Gas Supply for Bunson Burner

[JE-P&H]

I have been approached by a Dental Lab that would like a permanent gas supply for their Bunson burner. Not really clear on what the regulations etc are for this is it something I am allowed to do? It's a domestic size installation with just a combi boiler supplying the Lab and Dentist currently. Any help on this or where is best to look for more information on this would be appreciated!

( I am GSR just short of 10 posts to be able to apply)

Get onto gas safe.

schools where i have worked have had to have proving units fitted for bunsons.

As Killy Bing says, science classrooms in schools have the gas supply interlocked with a proving unit and solenoid.

Firewatch are the common ones I've seen.

I think gas safe will likely post you over to local building control tbh

as a Bunsen burner is pretty much an open ended pipe.

Isn't quite the everyday thing!

its not a classroom its a dental lab

i would get clarification from gas safe but at 1.25 kw's what you going to need a solenoid ??

Thanks guys, I am waiting on a response from Gas Safe will let you know what they say. Been looking at the proving systems for example the Intelligas 100P Gas Proving System. (Can't post a link) seems it will be a very expensive solution though!

Need an isolator as a minimum. Lever type at eye height. Clearly labeled.

Check out the IGE doc's. You will require a separate isolation (ECV) with proofing device.

Proofing device is a flare stack ?

Proofing device is a flare stack ?

No not a flare stack. A device which checks there is pressure in the downstream pipe before allowing the gas to be turned on. Used in school labs, just in case the pupils think it would be a hoot to turn the Bunsen Burners on when the main lab gas valve is off and leave it like that. The master comes in turns the gas on and there is gas hissing everywhere. The proofing system stops this happening.

Thanks again guys I have received a response from Gas Safe which was I expected really

"Unfortunately there is no specific guidance for gas installations in dental laboratories and I would recommend you follow your normal pipework guidance relating to support, protection, sleeving, etc.

IGE/UP/11 provides guidance for educational establishments and I’m aware your not working in a school but some of the guidance may be of use"


The guidance for educational establishments basically says that the tap should not be easy to turn On/Off and should be secure etc.

So from what I understand it's basically up to me how far I want to take the safety precautions, proofing device etc.

That's rubbish..... I once nearly got removed for A level chemistry . Connect tap to gas tap with 1/2 rubber hose. Turn on gas, wait for teacher to try and light Bunsen, then turn on tap. Water comes out of Bunsen at some rate.
Other one is light gas tap...... Go a few taps down and blow down it, 30' flame thrower.

Suspended for two weeks, £500 bill but a few girls thought I was funny!

We had a Laboratory as our Registration/Tutor room , and enjoyed that perk too much ( to risk getting outed) ...

Played similar game with sink drains / taps and spectacular water spurts ..!! god bless paper towels from bogs

it was always a laugh to open a gas point on the table slightly when the proving unit was testing, it would then fail, and then the teacher would have to re test it..........again.............and again..........and again!

Spoke with the customer today looks like we will be going ahead with a proofing device just to be 100% safe. Thanks for the advice!
