The mandated clearance between buried mortars and the wall of troughs or drums is

Explanation:
Two inches is the minimum clearance you must keep between buried mortars and the wall of the trough or drum. This small but important space acts as a safety buffer that keeps heat, flame, and any fragmented debris from contacting the wall directly. By maintaining this gap, the wall stays cooler, the risk of igniting nearby materials is reduced, and any debris can vent without immediately striking the wall. This distance is a standard safety measure for buried mortar setups, balancing protection with practical layout. If the gap were smaller, heat transfer and damage to the wall could increase; if it were larger, it wouldn’t provide significantly more protection and could complicate the arrangement.
