SECTION II – INSTALLATION

WARNING / CAUTION

DO NOT TURN ON THE ELECTRIC POWER SUPPLY to this equipment until heater is completely filled with water and all air has been released. If the heater is NOT filled with water when the power is turned on, the heating elements will burn out.

For protection against excessive pressures and temperatures, code requires the installation of a temperature-and-pressure (T&P) relief valve certified by a nationally recognized laboratory that maintains periodic inspection of production of listed equipment of materials, as meeting the requirements for Relief Valves and Automatic Gas Shutoff for Hot Water Supply Systems. ANSI Z21.22-1971. THE CUSTOMER IS RESPONSIBLE TO PROTECT PROPERTY AND PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS.

All water heaters have a risk of leakage at some unpredictable time. IT IS THE CUSTOMER'S RESPONSIBILITY TO PROVIDE A CATCH PAN OR OTHER ADEQUATE MEANS, SO THAT THE RESULTANT FLOW OF WATER WILL NOT DAMAGE PROPERTY.

WATER HEATER PLACEMENT

1.Place the heater on a solid foundation in a clean, dry location nearest to the point of most frequent hot water use.

2.The water heater should be protected from freezing and waterlines insulated to reduce energy and water waste.

3.Leave a minimum of 18” clearance for element withdrawal, if necessary.

4.Do not install in an area where flammable liquids or combustible vapors are present.

SECURING OF HEATER

1.The heater is supported by four 2-inch x 2-inch x ¼-inch thick angle iron legs each with a 3- inch x 3-inch x ¼-inch thick steel base pad. Each leg is provided with one 9/16-inch diameter bolt hole for one ½-inch bolt which should be used to secure heater to the deck.

2.In addition to the leg supports, two 3-inch x 3-inch x ¼-inch thick brackets with 7/8-inch diameter mounting holes are attached to the upper portion of the heater. These brackets should be attached to bulkhead secured tie-rods thus insuring further support of the heater for shipboard installation.
