Okay, so it turns out that my initial whining about assembly difficulties was a bit premature; the hardest part was peeling off that confounded blue protective film they feel necessary to coat the various surfaces with, although I DID have a problem getting the side-burner gas line - with its quick-connect fitting - to seat properly onto the nozzle. Perhaps it was the "newness" of the connector, but it took me - and the efforts of a neighbor - about twenty minutes to finally hear that "click" indicating a proper coupling.
I am tickled with the final result, however, and am especially impressed with those massive SS food grates! After firing her up, all the burners seem to be working correctly, with nice blue flames running throughout.
That said, I note that the user guide advises that the grill "...is designed to operate at 4.5 inches of water column pressure...". Presumably, that figure deals with promoting maximum burner efficiency.
Would it be advisable, therefore, to have a gas contractor check to see what the column pressure is in order to achieve maximum efficient output - making gas meter regulator adjustments as necessary - or may I simply go by a visual inspection of the burners? They certainly LOOK like they're doing what they're supposed to do.
I don't want to incur unnecessary costs, but then again, I'm not going to shell out the money I did for the grill only to quibble about ponying up a few more dollars to ensure it's working properly.
Anyone's thoughts would be appreciated.
