The model number will have the form H9 1262BD 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).

Refer to the Hi Delta manual for available firing options. 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. The final character is the letter “D” which designates the heater as a FlexGas equipped heater.
