In addition to the five elements found in every serial number, the heater serial number may be
coded with prefixes and suffixes that further identify optional equipment or capabilities applicable
to that particular unit. All prefix and suffix codes are listed below. See pages 3-4 for explanation
of the basic elements of a serial number.
