I going to guess this isn't a legit BBQ store but a place that sells lots of out door stuff so they don't really specialize in any of their products.At least I would hope so because that's the only way I can explain poor service like that without any back up. might be better off emailing the manufacturer about it all.The shop i bought it from did the jet change for natural so im assuming they changed the reg to suit as well.How can i tell if its correct is there some markings or code on it.
The shop arent being very helpful and they dont seem to be able to offer anything other than say its my gas pressure ,but it was fine before on the last bbq.
