When this water heater system is supplying general purpose hot water requirements for use by individuals, a thermostatically controlled mixing valve is recom- mended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.

Thermometer(s) should be installed so that they indi- cate the water temperature at or near the outlet of the storage tank.

Relief Valve

A new combination temperature and pressure (T & P) relief valve, complying with the Standard for Relief Valves and Automatic Gas Shut Off Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed in the opening provided on top of the storage tank, at the time of installation. No valve is to be placed between the relief valve and the storage tank.

The pressure rating of the relief valve must not exceed the 160 maximum working pressure indicated on the water heater rating plate. The BTUH rating of the relief valve must not be less than the BTUH input of the heater.

Connect the outlet of the relief valve to a suitable open drain. The discharge line must pitch downward from the valve to allow complete draining (by gravity) of the relief valve and discharge line.

The discharge line should be no smaller than the out- let of the valve. The end of the discharge line should not be threaded or concealed, and should be protect- ed from freezing. No valve of any type, restriction or reducer coupling, should be installed in the discharge line. Local codes shall govern installation of relief valve.

Temperature & Pressure Gauge

The temperature and pressure gauge is standard equipment on all hot water heaters. All temperature and pressure gauges are shipped loose for field instal- lation in the outlet water connection (see Fig. 7). All fittings required to mount the gauge to the piping are supplied by others.

Electrical Wiring

The electrical power supply requirement for these heaters is 120 volts, 60 Hz. Field wiring connections and electrical grounding must comply with the local codes, or in the absence of local codes, with the latest edition of the National Electrical Code, ANSI/NFPA 70.

Provide a separate fused circuit from the main electri- cal panel to the heater, and a disconnecting means within sight of the heater.

Remove the control box cover and make the power supply connections in the field wiring compartment. (See general location of controls drawing). The pump is supplied and factory wired to operate with the heater. The thermostat (tankstat) is shipped loose to be installed in the tank at the installation site.

WARNING: SHOCK HAZARD: Line voltage is present. Before servicing tankstat or heater, turn off electrical power to the heater at the main disconnect or circuit breaker. Failure to do so could result in severe personal injury or death.

NOTE: Minimum 18 AWG, 105°C, stranded wire must be used for all low voltage (less than 30 volts) external connections to the unit. Solid conductors should not be used because they can cause excessive tension on contact points. Install conduit as appropriate. All high voltage wires must be the same size (105°C, stranded wire) as the ones on the unit or larger.

NOTE: If it is necessary to replace any of the original wiring, it must be replaced with 105°C wire or its equivalent, except 150° black wire which must be replaced with 150° wire or its equivalent.
