I checked out a Utica boiler today but am having a difficult time trying to identify the age. Serial number starts with HZ. I referenced the age chart on building-center.org but it doesn’t list a year for the letter Z. Has anyone ran into this before?
Up until 2003 Utica useda month/year code. The month was A - L. The year was A + 1984 through Z = 2002 (except for 2000 when they used 9 for units made from jan - aug and X for units made sept - dec). In 2003 they started using a sequential code.
