The proper pitch for a horizontal hot gas line in a refrigerant system is indeed 1/4 inch per 10 feet of run. This specific incline is recommended to ensure effective drainage of any condensed refrigerant that may accumulate in the line. Adequate slope allows for proper refrigerant flow and prevents potential issues such as slugging, where liquid refrigerant enters the compressor, which can cause damage.

In refrigeration systems, it is crucial to maintain the correct pitch for horizontal lines to promote efficient operation and to avoid complications that can arise from improper drainage. A 1/4 inch per 10 feet pitch is commonly specified in industry guidelines because it strikes a good balance between ensuring sufficient drainage without being so steep that it creates other flow issues.

The other options do not align with industry standards for refrigerant line installation, as they either suggest too steep of a pitch or too shallow, potentially leading to drainage problems.
