Is it a Bird? Is it a Jet?

We won't even bother with Superman............

I have two gas rings which sit directly on top of 1.25 kg. bottles, and I know they are jetted, because I have bought spares.

I also have a Coleman 2 burner stove, which connects to a bottle, using a hose & regulator. Because of the regulator, is the stove jetted... or not?

If it IS... then why the regulator?

Cheers

Thankyou Ray.

So, if I leave it connected to my bottle, I should therefore never have a dust related blockage?

Cheers

Well you wont have a problem with the jets blocking :)

Just leave it connected if that's what you want

The regulator is not for anything other than keeping a constant pressure to the appliance , i think about 1.1kpa at all times or it tries to .
If the bottle gets hot the presure builds and the gas then goes to the stove at a higher presure than it's designed to cope with .

I don't think i have ever seen a burner that doesn't have an Injector at least before the venturi on the burner rail or at least in the burner itself ,thats probably the case with the coleman i suspect if there is not one before the venturi.
Burners need an injector( jet) to work properly even pilot lights all the way up to some industrial types( excluding power burners) .

The injector gives the burner the correct measured amount of gas for the BTU rating it was designed for . For example a common gas BBQ on LP has an injector size of say 1.13mm whereas the same BBQ on natural has an injector size of 1.75 because of it's lower BTU (British Thermal Units) rating in the gas .

Bugger!!

Now I AM confused....

When you say either 1.13 mm.... is that cross sectional area, eg. 1.0 mm. dia?

If the orifice is around say.... 0.75 mm. - 1.0 mm., then I don't think dust would be an issue ( hopefully).

The low pressure devices don't have a tiny jet susceptible to blocking like the high pressure units. Blocking with the low pressure devices is very uncommon because of the large orfice.

Yeah and that's why a lot of people buy the coleman unit Wolfie...not susceptible to blocking like those yellow jobs.

The reason for the smaller and larger hole is this .

LPG has a higher energy (Heat) rating eg , more heat for the same amount of gas so it requires a smaller hole .

Natural gas has a lower energy rating for the same amount of gas so it needs a larger diameter hole to work right .

The only difference between a gas cooker (BBQ, HWS etc) on LPG and Natural is the larger and smaller sized injector holes and the regulator pressures set to whatever the appliance requires as per the instructions .

Okay, next question......

Is there such thing as a quick connect / disconnect for LPG which is dust-proof, and can be put in line between my stove & bottle?

Something like my Air Lines at work, where you pull back the collar, and it disconnects.

Hey Wolfie

You're not quite in the clear yet mate.

We have a similar Coleman and it ceased to function correctly up north ... read stuff all flame.

It turns out the regulator contains a very fine gauze which became blocked. Apparently Aus gas is fairly "dirty". The camping shop sent it off to Coleman who have a way of opening the factory sealed regulator and removing the offending gauze. Since them no probs, but it may be something for you to look forward to.

Cheers cob

P.S. Cost about $30

hahaha, after our second rate petrol and diesel it's not surprising that our gas is the same No wonder we are regarded as a dumping ground for second rate goods.
