Don't use black iron pipe - it rusts (on the inside) and that rust can block up orifices. Natural gas is "supposed" to be dry - but even a small amount of water vapor causes problems. There is a special designated NG pipe that is yellow and is far better. Tracer wire (sometimes now called pressure "tape") is essential for plastic pipe. Some NG pipes come with the tracer wire embedded in the wall of the plastic pipe.

Am not sure if 24 inches deep meets code - double check. Depends if it is high or low pressure in some jurisdictions.

Where is the pressure reducer? In some situations it is at house (after meter) in others it is before meter.

If after reducer a 3/4 " pipe is plenty to supply 38 kBTU.

An easy project - trenching is the big part. But machine trenching close to the meter, and the existing service NG pipe, can be . . . . exciting. Sounds obvious, but buy a good manual trenching shovel for that part. FWIW, in retrospect, I (and I bet more than a few people on this site) have trenched too close to a gas line and have been lucky.
