BEFORE INSTALLATION

Raypak strongly recommends that this manual be re- viewed thoroughly before installing your Hi Delta heater. Please review the General Safety information before installing the heater. Factory warranty does not apply to heaters that have been improperly installed or operated. (Refer to the warranty at the back of this manual.) Installation and service must be performed by a qualified installer, service agency or gas supplier.

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

Product Receipt

On receipt of your heater it is suggested that you visu- ally check for external damage to the shipping crate. If the crate is damaged, make a note to that effect on the Bill of Lading when signing for the shipment. Remove the heater from the shipping packaging. Report any damage to the carrier immediately.

On occasion, items are shipped loose. Be sure that you receive the correct number of packages as indi- cated on the Bill of Lading.

Claims for shortages and damages must be filed with the carrier by consignee. Permission to return goods must be received from the factory prior to shipping. Goods returned to the factory without an authorized Returned Goods Receipt number will not be accepted. All returned goods are subject to a restocking charge.

When ordering parts, you must specify the model and serial number of the heater. When ordering under war- ranty conditions, you must also specify the date of installation.

Purchased parts are subject to replacement only under the manufacturer’s warranty. Debits for defec- tive replacement parts will not be accepted and will be replaced in kind only per Raypak’s standard war- ranties.

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 1262B 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).
