Raypak 751 Before Installation, Product Receipt, Model Identification, Ratings and Certifications

BEFORE INSTALLATION

Raypak strongly recommends that this manual be re- viewed thoroughly before installing your ADB heater. Please review the General Safety information before installing the heater. Factory warranty does not apply to heaters that have been improperly installed or oper- ated. (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. If, after reviewing this manual, you still have questions which this manual does 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.

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 left inside jacket of the heater. The model number will have the form H4-0751AADB or similar depending on the heater size and configuration. The first charac- ter of the model number identifies application (H = Hydronic Heating System, W = Hot Water Supply System, P = Pool Application). The second character identifies the firing mode (4 = On-Off firing). The next four places identify the input of the heater in 1,000s of BTUH 0751 = 750,000 BTUH). The remaining suffix identifies the control, ignition, and construction config- uration. The last three characters of the model number identifies the model type (ADB = Advanced Design Boiler).

Ratings and Certifications

Standards:

•ANSI Z21.13 · CSA 4.9 - latest edition, Gas-Fired Hot Water Boilers

•CAN 3.1 - latest edition, Industrial and Commercial Gas-Fired Package Boilers

•ANSI Z21.10.3 · CSA 4.3 - latest edition, Gas Wa- ter Heaters

•SCAQMD Rule 1146.2

All Raypak heaters are National Board Approved, and design-certified and tested by the Canadian Standards Association (CSA) for the U.S. and Canada. Each heater is constructed in accordance with Section IV of the American Society of Mechanical Engineers (ASME) Heater Pressure Vessel Code and bears the ASME stamp. The heater also complies with the latest edition of ASHRAE 90.1 Standard.

WARNING: Altering any RAYPAK pressure vessel by installing replacement heat-exchangers, tube bundle headers, or any other ASME part not manufactured and/or approved by RAYPAK will instantly void the ASME, and agency listings and any RAYPAK warranty on the vessel. Altering the ASME, agency ratings of the vessel also violates national, state, and local approval codes. The terms "boiler" and "heater" are used interchangeably in this manual.

Installations at Elevation

No de-rating is required for altitudes up to 7000 feet. Rated inputs, at sea level settings, are suitable for up to 5000 feet elevation. At altitudes between 5000 and 7000 feet, rated inputs are achieved with pressure set- tings adjustment. Consult the factory for installations at altitudes in excess of 7000 feet.
