Product Receipt

WARNING: Pump motors should NOT be supported by any type of stand or support from above due to possible misalignment of pump and motor which may occur.

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. Next, 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. Parts 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 data plate located on the right side jacket of the heater. The model number will have the form H3-HD101 or similar depending on the heater size and configuration. The first character of the model number identifies application (H = Hydronic Heating System, WH = Hot Water Supply System). The second character identifies the firing mode (3 - two stage firing, 4 - On/Off firing ). The next three places identify the size of the heater.
