Is a drip leg required at the connection to a water heater from a natural gas line?

G2419.4 Sediment trap. Where a sediment trap is not incorporated as part of the gas utilization equipment, a sediment trap shall be installed downstream of the equipment shutoff valve as close to the inlet of the equipment as practical. The sediment trap shall be either a tee fitting with a capped nipple in the bottom opening of the run of the tee or other device approved as an effective sediment trap. Illuminating appliances, ranges, clothes dryers, decorative appliances and outdoor grills need not be so equipped unless specifically required by the appliance manufacturer's installation instructions.

Thanks gentleman.

A drip leg no, unless your utility company uses wet gas. A sediment trap or "dirt leg", yes, as required by IRC.

The two terms are often and erroneously used interchangeably.
