WARNING: This FlexGas heater is intended for operation on Natural Gas as the primary fuel. DO NOT use this heater on Propane Gas as the primary fuel.

Raypak strongly recommends that this manual be reviewed thoroughly before installing your Hi Delta heater equipped with FlexGas. Raypak also recom- mends that the appropriate Hi Delta Installation and Operating Instruction manual (1000.501 for 302B- 902B or 1000.511 for 992B – 2342B) be thoroughly read before attempting to install these heaters. Fac- tory warranty does not apply to heaters that have been improperly installed or operated. (Refer to the warran- ty at the back of the standard Hi Delta manuals.) Installation and service must be performed by a quali- fied installer, service agency or gas supplier. If, after reviewing these manuals, you still have questions which these manuals do not answer, please contact the manufacturer or your local Raypak representative.

Thank you for purchasing a Raypak product. We hope you will be satisfied with the high quality and durability of our equipment.

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 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). 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. 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.
