[C320-list] Gas pipe thread

[Graeme Clark]

Can anyone please tell me what standard pipe thread is used to make the hose connection to the Seaward range cooker in the 320?

In Britain all has and water pipe threads are BSP but I suspect this US manufactured range will use whatever the US standard is. 
Converters are available of course, but I need to know what I am converting to!

Many thanks
