The first letter of the serial number denotes the year of manufacture, based on the listing below. The serial number may be noted on two lines, as below, or one line.
A = 1994 B = 1995 C = 1996 D = 1997 E = 1997
F = 1998 G = 1999 H = 2000 J = 2001 K = 2002
L = 2003 M = 2004 N = 2005 P = 2006 R = 2007
S = 2008 T = 2009 U = 2010 V = 2011 W = 2012
X = 2013 Y = 2014 Z = 2015
(We assume that the cycle repeats, with A = 2016, etc.,
but not confirmed)
So the “I” in the serial number above indicates the unit was manufactured in 2001. This serial number system is used for both the “AquaTherm' and 'U.S. A/C Products” equipment made by First Co., that circulate the hot water from a gas or oil-fired water heater to the air handler for heating a home.

PeerlessPrior to 1984 there was not a date code included as part of the serial number. Starting in 1984, there was a four digit date code following the serial number that was month and year. Example - JO-12345-1084, this unit was built in October of 1984. Starting in the year 2000, same idea only it was a six digit date code following the serial number that is year and month. Example - 1234567-200105, this would have been build in May of 2001.
Anything without the addition to the serial number would have been made before 1984 and would require contact with the factory.
