The first letter in the s/n is the year of manufacture with A being 1964 or 1984 (they use a 20 year cycle). They skip the letters "I, O, Q, R, U, and V" to make the full cycle.
Due to a computer error, Bradford-White manufactured some water heaters with a s/n beginning OA. These units are from January 1997
