Why doesn't my new Natural Gas Barbeque fit on the outlet on my house? - natural gas barbeque

We bought a new gas grill today and installed. I think natural gas is certainly the case, it is said that (the possibility of natural gas or propane gas, had been clearly identified, and both boxes).

When it comes to defining the grid of natural gas pipe from the house the man, but a little too small. Leaving the house seems to be somewhat larger than the connector on the grill. Maybe a 1 / 8 inch or less.

This is a new home. Is there anything to do that? The manufacturer missed something? Please help! Of course we were waiting for the night of the barbecue ... to plan B!
