Rapido External Gas BBQ Connection Point

Hi, we have an external connection point for a gas fuelled BBQ on the side of our Rapido 7099F.  My question quite simply is, "do we need to add in another regulator between the bayonet connection and the Cadac gas burner, or is the fixed regulator in the gas store cupboard sufficient?".

My instinct tells me that I am worrying unduly, and that I need only use a hose fitted to the connector and out to my BBQ connection, but I thought it worth asking the question.
