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). NOTE: Not all these firing options are available on all heaters. Refer to the Hi Delta manual for available firing options.
