Preparing for the Installation

1.Read the “General Safety” section of this manual first and then the entire manual carefully. If you don’t follow the safety rules, the boiler may not operate safely. It could cause DEATH, SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE.

This manual contains instructions for the installation, operation, and maintenance of the electric boiler. It also contains warnings throughout the manual that you must read and be aware of. All warnings and all instructions are essential to the proper operation of the boiler and your safety. READ THE ENTIRE MANUAL BEFORE ATTEMPTING TO INSTALL OR OPERATE THE BOILER.

Detailed installation diagrams are in this manual. These diagrams will serve to provide the installer with a reference for the materials and method of piping suggested. IT IS NECESSARY THAT ALL WATER PIPING AND THE ELECTRICAL WIRING BE INSTALLED AND CONNECTED AS SHOWN IN THE DIAGRAMS.

Particular attention should be given to the installation of thermometers at the locations indicated in the diagrams as these are necessary for checking the operation of the heater.

Be sure to turn off power when working on or near the electrical system of the heater. Never touch electrical components with wet hands or when standing in water. When replacing

fuses always use the correct size for the circuit. See page 12 through 14.

The principal components of the heater are identified on page 8. The model and rating plate on page 9 interprets certain markings into useful information. Both of these references should be used to identify the heater, its components and optional equipment.

2.The installation must conform with these instructions and the local code authority having jurisdiction and the requirements of the power company. In the absence of code requirements, follow NFPA-70 (current edition). The National Electrical Code may be ordered from: National Fire Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

3.If after reading this manual you have any questions or do not understand any portion of the instructions, call the toll free number on the back cover for further assistance.
