gas bottle with regulator/or without

[wmarsb]

need some advice, why do some gas appliances have a regulator and some don't. I have a home made spit but the gas goes out frequently and we have
a regulator on the bottle. what damage could I do if I tried it on just a direct feed. I don't wont to blow the hell out of the carport when the wife lights it. I intend to stand clear, no good both of us getting hurt.

The gas before the regulator is at a lot higher pressure
Remove it and you could create a bomb
We will read about it in the papers
Leave the regulator in place it is there for a good reason

You may need a new regulator...they are quite cheap

Hi 
Home made ??
Where did you get It?

Adapting gas burners for a use they are not designed for needs experts.

I hope you know you are playing with a potential bomb
Your problems could be a combustion problem & lead to an explosion !!
I suggest you destroy it, then dump it
OR get a gas proffesional to look at it

I do understand that, but just bought a new bbq and the hose comes without a regulator, yet the old one has a regulator. how do you determine what needs a regulator and what does not.

The regulators convert high to low pressure. Even the big gas bottles beside my house (90kg) have regulators. As Allan said remove the regulator + potential bomb.  Regulator at Bunnings about $15 plus 15mm of hose with brass fittings around $15.

The newly bought BBQ simply came without a reg.

Check with the manufacturer or the retailer where you bought it  to see if you should have a regulator
Do not use it until you find out

why do some gas appliances have a regulator and some don't

I'd like to know the answer as well, a camp stove I have operates without a regulator.

There are two different gas appliances so to speak, high pressure and low pressure. Your standard home 4 burner Jackeroo BBQ from Kmart is a low pressure appliance, hence it has a regulator to drop the gas pressure as it comes out of the bottle to L/P. I think gas bottle pressure is around 800-900kpa and the reg will drop it down to about 3kpa but dont quote me on this.

Your Gasmate gas stove that you have in the camper trailer is a high pressure appliance, hence they do not have a regulator in the line from the bottle to drop the pressure instead they use a very small hole in the form of a jet which is located behind the on/off and temp control knob to control the amount of gas being delivered to the burners.

Dont ever remove the regulator from a L/P hose and light the gas or as said above we will be reading about you in the papers.

From the Elgas web site:
The pressure within a gas bottle can be 800-900kPa. This varies based on the ambient temperature, exposure to the radiant heat of the sun and the amount of gas remaining in the gas bottle. However, the required appliance inlet pressure for Australian LPG gas appliances is typically only 2.75kPa. So, a regulator is required to reduce the pressure and ensure a consistent 2.75kPa is safely delivered from the gas bottle to your appliances.
