Hi Ann & John,
I take it that you have an exteral BBQ point on your Bailey ?
We run our Cadac from the external BBQ point on our Bailey and use the connector that was supplied with the van.
This is a small piece of metal tube that joins the rubber gas pipe from the Cadac to the gas outlet on the offside of the van.
It came in one of the plastic bags containing user insructions for the van and i'm sure it was wrapped in foam.
If your van does have an external BBQ point and the dealer didny supply you with the adaptor, I would be asking them for one !
Hope this helps,
Ken & Lara.
