Regulator for LPG gas cooktop??

[Pulpo]

I have just purchased an LPG gas cooktop [Simpson]

I have been told the regulator is a long brass nut 50mm with a screw sticking out one side.

The nut [regulator] has an arrow I assume to indicate which way the gas flows.

The screw/small bolt does not seem to go through the nut, cannot see its purpose.

Can someone comfirm, if this is a regulator for an LPG cooktop?

And what is the purpose of the screw?

The instructions are dreadful.

Many THanks

The regulator should be attached to your gas bottle. Don't tamper with gas. Get yourself a licenced gasfitter or plumber to connect it otherwise you may end up living on a vacant lot. BOOM

Our cooktop ha a similar fitting, apparently it operates at a lower pressure than our other appliances so the fitting goes in-line immediately before the cooktop. The bolt is the adjuster, but if it came with the cooktop the odds are that it has been factory preset. And yes, the arrow is the flow direction indicator.

Just the same, your best bet is to have a licensed gas-fitter install it. Some things really aren't worth trying to save a penny on and gas leaks tend to have BIG consequences.

Methinks you'd get the same advice from almost everybody on this board...

Don't do what I did - mix up a low pressure regulator and a high pressure regulator - Stoves definitely DON'T like high pressure when it should be low pressure.

Luckily the sink with plenty of cold water was just a step away when I got the thing to light - everyone was asking where the bad smell came from - it was my hair.:eek: Well it did grow back after a few weeks.

Low pressure regulator look like a UFO - a disk shaped thing with lumps on it, commonly used with BBQ's

High pressure regulator looks like a brass cylinder about 25mm x 75mm with a knurled knob on one end, no lumpy bits sticking out.

The Long piece you have is not a regulator, it is a convienient test point that a manometer can be connected to, to check that you have the correct flow rate for your cook top. If using bottled gas this doesnt have to really be checked, but you will have to change the jets for each of the burners. The test point is more for town gas that is regulated ( with a seperate reg usually supplied with the cook top ) just prior to the cook top, and is adjustable. Bottled gas has smaller jets due to the different opperating pressure and the supposidly higher energy yeild per LB of gas.

The flow direction is marked on the fitting as it is being used as an oriface plate to do the measuring, and it wont work fitted the wrong way round. But it will still let the cook top work perfectly fitted either way!

If the fitting you have is an aluminium one, be very carefull not to over tighten as it will surely split.

Thanks all

The gasfitter had left everything ready to install the cooktop, and told me I only had to connect and install the cooktop.

He was going on holidays, and I wanted it done now.

Nothing seemed too difficult and the gasfitter was comfortable with my ability to connect a few fittings.

...er, so why the question?

IF all of the parts are correct, I would use thread tape on all of the connections, and check for leaks with soapy water with the gas on before lighting anything. I think there should be a hole at the base of the cupboard to let gas escape outside.

If you are in any doubt, have it checked, or use the barbie till the plumber gets back. Don't frig with invisible things that can kill.

[I]Tassiekiwi Why the question?[/I]

The cook top had not arrived until after the plumber left.

So I was not sure if all the parts were correct.

The plumber made no mention of a regulator I just assumed one was required.

It seems a common occurrence for me to have parts missing from appliances or the like.

I wanted to call the plumber but he had gone bush and was not even in mobile range.

After calling the suppliers, the manufacturers, and the gas company I was give three different pieces of advice.

I could elaborate on their advice but suffice to say the supplier was spot on, as I now know.

Hence I needed more or further guidance, which is what I always receive from this bulletin board.

Yes I will use yellow Teflon tape for the fittings, thanks.

Beware using tape on your joints. Tape is only used if the thread is the sealing point. Usually the fittings are a seating type whereby sealing PASTE is used . Wait for the gas fitter PLEASE!
