Price - $5.00 00934-0 R - /07 GENERAL INFORMATION PLEASE READ INSTRUCTIONS CAREFULLY BEFORE INSTALLING WATER HEATER U.S Boiler Company, Inc. – Burnham Hydronics (herein called the Company) intends that this Alliance SL™ Indirect-Fired Water Heater be used as a separate zone to a heating system boiler. This appliance is designed to heat water by circulating water from the boiler through the internal coil in the tank. We specifically do not warrant this tank for high temperature applications such as wood stoves or steam producing systems. Such use of this product will automatically void the warranty. The design anticipates the proper installation and care in use of the product. There is risk of property damage and personal injury inherent in the use of any hot water system. The Company cannot supervise the installation and therefore makes it a specific condition of the warranty that the customer will supervise the installation and use of this product to be sure they are performed in accordance with safe guidelines and proper local or national codes. Generalized instructions and procedures cannot anticipate all situations. For this reason, only qualified installers should perform the installation. A qualified installer is a person who has licensed training and a working knowledge of the applicable codes, regulations, tools, equipment and methods necessary for safe installation of a boiler system and an indirect water heater. An installation checklist has been provided to help the customer ensure that all procedures for a safe installation have been followed. If questions regarding installation arise, check with your local plumbing and electrical inspectors for proper procedures and codes. Local codes take a precedent over instructions in this manual.
