About this file
This is a Special Packaging Instruction (SPI) document for a Water Heater, 400,000 BTU (WH-400) with National Stock Number 4520-01-566-6669. The document specifies detailed packaging requirements for this military equipment manufactured by cage 51419, with an effective date of 01 October 2026, Revision A.
The packaging procedure requires construction of a wooden container base using 2x6 boards and a 4x4 board as shown in Figure 1, with drilled holes aligned to the heater assembly frame rail holes for forklift entries. The heater assembly must be centered and fastened to the base using 1/4 X 2-1/2 inch lag screws with flat washers (P/N 15302, CAGE 92878), with acceptable hardware options including commercial grade steel with zinc plating per MIL-PRF-16173, Grade 4, or stainless steel. The heater is then strapped to the base using nylon strapping per ASTM D3950, Type III, and wrapped with commercial stretch film (ASTM D3951) using four or more layers, ensuring the UID label remains visible. The final shipping container, a modified ASTM D6251, Type III, Class 2, Standard A box measuring 47-1/2 X 31 X 46 inches, is closed using minimum 2-inch galvanized nails spaced no more than 5 inches apart. The unit pack specifications include a weight of 668.0 pounds and cubic measure of 51.654 cubic feet, with overall dimensions of 50.3 X 33.8 X 52.5 inches. Quality assurance requires inspection per MIL-STD-2073-1, and marking must conform to MIL-129.
