GAS BARBECUE HELP PLEASE

[tinamic]

WE'VE BOUGHT A GAS BARBECUE FROM ARGOS & PUT IT TOGHETHER FOLLOWING THE INSTRUCTIONS BUT WHERE THE PIPES FROM THE BURNER ATTACHES TO THE GAS ORIFICE IT DOESN'T SEEM TO CONNECT VERY WELL AND THERE ARE VENT HOLES IN THE SIDE OF THE PIPES FROM THE BURNER, SURELY THE GAS WILL ESCAPE THROUGH THESE. WE ARE THINKING OF JUST TAKING IT BACK BUT WE'VE JUST HAD THE GAS BOTTLE DELIVERED AND HAD PLANNED A BARBECUE FOR MY SON'S BIRTHDAY TODAY. I'M SCARED OF TRYING IT OUT. PLEASE HELP
