Help connecting gas bottle to Weber BBQ

[ChrisHGTV]

This was in the online manual from Weber Cyprus but I also received a manual with the box that wasn't in English but this is what it says:

"What Is LP Gas? Liquefied petroleum gas, also called LP, LP gas, liquid propane, or simply propane or butane, is the flammable,petroleum-based product used to fuel your grill. It is a gas at moderate temperatures and pressure when it is not contained. But at moderate pressure inside a container, such as a tank, LP is a liquid. As pressure is released from the tank, the liquid readily vaporizes and becomes gas."

I’ve just looked at my Broil King instructions and it says I can run it on propane (same as patio gas in UK), or butane. So I don’t think the burners etc have to be specific to the type of gas. Reading more, butane seems better for hot countries, and propane colder countries due to the lower boiling point of propane. But basically it seems either is fine. I seem to remember reading before that the term in the UK of “Patio gas” has more to do with the cylinder being equipped with a contents indicator but it’s just propane. This is what I use as it’s nice to see how much gas you have left.

, but what I really need to figure out is, if it is a propane grill to be used solely with 100%/ propane, how does using a mixture of propane/butane affect things, and is it safe

In all probability both safe and unaffected by mixes of the two.
Automotive LPG is predominately propane but with varying degrees of butane added. No calibration changes are required with different proportions of propane/butane. It is with domestic gas boilers that a change from/to natural gas (predominately methane) to LPG/propane/butane that recalibration in the form of smaller/larger flow passages is required. And that is because of the density difference between methane and LPG/propane/butane.

But isn't Calor just a brand, and they sell propane and butane? So it appears your wife is confusing things as well haha. In Cyprus they call telehandlers just plain forklifts and all cereal are "cornflakers" even when it's not.

The orange bottle isn't a mix of Calor, I am sure it's just the brand, but it might be a mix of propane and butane, and I've emailed the company to ask. I have a feeling I read somewhere it's a mixture of 70% butane to 30% propane.

It says in the manual that "this grill has only been safety tested for the country of use, refer to the country listed on the outside of the box" however we often get products here with the wrong EU adapter etc and it also came with the wrong regulator for the only gas bottle they sell here, so I can't be confident. I'll email Weber Cyprus as well just to ask, but they are just a local store using the Weber name to supply parts but they should know something, but what I really need to figure out is, if it is a propane grill to be used solely with 100%/ propane, how does using a mixture of propane/butane affect things, and is it safe. No sure thing as patio gas here but I'd assume if Weber authorise their product to be sold in Cyprus, they would know what the gas is that is used.

My wife confused? It’s a brave man that says that, something I avoid haha.
Back home in Egypt all cylinders are orange but I think the logic is probably the same as Cyprus- it’s gas-it’s Calor. It seems orange Calor is Propane from what I now read.
This took my interest because here in the UK all cylinders are colour coded and I’ve always stuck to manufacturers recommendations but it does seem you can use Propane or Butane, provided you have the correct regulator.
It seems jet size doesn’t matter too much but the mix of gas and air does. On another website there was concern about the length of connecting hose.
You’ve taught me a lot. I always new Egypt was different with all those orange cylinders but didn’t question it.
(First experience of bbq there 40 years ago was a square biscuit tin and a wood fire but it worked).
