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, local codes require 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 FURNISHINGS OR PROPERTY.

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

3.Leave sufficient clearance for element withdrawal, if necessary.

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

PIPING INSTALLATION

NOTE: The most effective means for preventing deterioration from accelerated corrosion due to galvanic and stray current is the installation of dielectric fittings/unions. The installation of these fittings is the responsibility of the installing contractor.

1.Connect the cold water inlet and hot water outlet to the appropriate connections as shown; refer to the drawing for location and sizes.

2.Install in-line vacuum breaker and in-line pressure and temperature gauge, if supplied.

3.Install the combination temperature and pressure safety relief valve in the tapping provided. Note that this is required by law for safety considerations.
