Just a little tip when connecting your BBQ or BBQ's to a Natural Gas Bayonet socket in your outdoor area:
If you have two seperate Barbeques, say a two burner and a four burner BBQ with a side burner, it requires two 'seperate' supplies. Say you buy a Turbo Classic 4 (plus side burner) and a Turbo Classic two burner, you can bolt the two together, BUT each BBQ MUST have TWO seperate supplies of Gas, beit Mains or LPG Gas, otherwise this manufacturer would have made a 6 burner BBQ with one supply. They havent because the output is too great for most bayonets to handle.
Most bayonets have a limited amount of Natural Gas that can be supplied through the socket so if the BBQ has more input of Gas than the point can supply, the presure may be too low to cook efficiently. If you double up on the bayonet to create two supplies this will not normally help as the supply to both is coming from the same pipe.
So, a solution is to 1/. run the two burner on LPG and the four on Natural Gas or
2/. run a seperate bayonet socket from the Natural Gas ring main in the roof or ground, so each BBQ has a seperate supply.
Hope this helps....
