Regulator, O' Regulator, where art thou ?

[Mad Manny]

On my Conqueror Trailer I have a 5kg gas bottle.
This is plumbed, through the wall, to my cheap Cadac 2 plate stove.
There is no regulator in the system.
The Cadac works well.
When I bought it, it was branded LP.
Everyone told me it stood for LP Gas.
I'm 99% sure it was for Low Pressure.

I decided to upgrade & bought a new Cadac deluxe 2 plate stove.
The new one can run on SA LPG, Butane etc. etc.
The new one comes with a regulator.

I'm a bit confiussed as to why the old one needed no regulator & the new one does.

I assumed that the 3 & 5 kg bottles are too low pressure to need regulators while the 9kg up, which have bigger outlets do.

I called Andre Strauss as he is an overlander, 4x4'er, Plumber & Gas installer & asked him.
Trust me - he has no idea why the old one was happy with no regulator.

Anyone have an idea?.

Doesn't answer your question but LPG=liquefied petroleum gas

I see Chas answered while I was typing

Cadac prefer to use jets to regulate gas flow. All Cadac skottel braais, burners and other stuff is regulated via a jet in the feed to the equipment.

Most other manufacturers uses regulators.

So in your Cadac system there would be a jet somewhere

Grips has the correct answer. The older burners had a jet where the burner’s knob opened the gas flow, it limited the gas flow.
Remember the little metal ring you had on a gas lamp and heater? That helped to mix the air gas volume for optimal burn.

Thanks guys.
So the Jet did the job of a regulator hence LP.

Kind of what I suspected but wasnt sure.

I'll fit the regulator with the new one.

Cheers!

Erno, I mainly use the stove to boil water, it's a bit slower if you have to make a fire everytime...
