We had a firepit put into our back yard, the gas line runs roughly 20 feet to the Fire Pit. I believe our line is a 3/4" line and we put in 3/4" pipe to the Fire Pit. I'm really displeased with the Fire that the line and burner are producing and was wondering what my options were, and had a few questions:
Would it be beneficial to have a 3/4" line run underground and come up at the fire pit through a 1 1/4" gas pipe, or would that not produce more gas at the pit?
Is my line actually a 3/4" line? It looks to measure at 3/4", but the Flex Hose coming out at the Fire Pit is a 1/2" line as far as I can tell. The contractor says we aren't downstepping and its a 3/4" pipe on the outside, but that the line is actually 1/2". I've attached picture of both the line from the house and the line at the fire pit.
Is it possible there is something wrong with the gas pressure at the Meter, or is the size of the fire coming out of a 30" stainless steel Fire Ring to be expected given our current gas line size? I've attached a few pictures below to hopefully help.

I'd appreciate any help I could get on this topic as i'm at a bit of a loss and am really disappointed about the results that the gas line is producing, it's a dinky fire that really couldn't warm up much of anything and am hoping to try to find solutions for the problem.
