Model Identification

The model identification number and heater serial number are found on the heater rating plate located on the lower right outside jacket of the heater. The model

number will have the form H9 1262A or similar depending on the heater size and configuration. The letter(s) in the first group of characters identifies the application (H = Hydronic Heating, WH = Domestic Hot Water (DHW), P = Pool). The number which fol- lows identifies the firing mode (1 or 4 = on-off, 3 =

2-stage, 8 = 3-stage and 9 = 4-stage). The second group of characters identifies the size of the heater (four numbers representing the approximate MBTUH input), and, where applicable, a letter, indicating the manufacturing series. An “E” suffix indicates 87% effi- ciency (Category II or IV venting) (“H” stamped boilers only).
