General Information continued-
THERMOSTATICALLY ACTIVATED MIXING VALVE – An ASSE approved thermostatic mixing valve is
supplied with the water heater. The solar heating system may transfer heat into the water heater above the
temperature limits set by the thermostats. This may create the potential for scald injury. To protect against injury,
you must install the supplied ASSE approved thermostatic mixing valve (a device to limit the temperature of water to
protect against scald injury via mixing hot and cold water supply) or equivalent in the water system. This valve will
reduce point of discharge temperature in branch supply lines if adjusted properly. Refer to the instructions supplied
in the ASSE approved thermostatic mixing valve box for installation procedures and device specifications.
TEMPERATURE AND PRESSURE RELIEF VALVE
CAUTION
This water heater must NOT be operated without the ASSE approved thermostatic mixing valve
included in the box with the heater or equivalent.
WARNING
Keep clear of the combination temperature and pressure relief valve discharge line outlet. The discharge
may be hot enough to cause scald injury. The water is under pressure and may splash.
For protection against excessive temperatures and pressure, install temperature and pressure protective equipment
required by local codes, but not less than a combination temperature and pressure relief valve certified by a
nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or
materials as meeting the requirements of the Standard for
Relief Valves and Automatic Gas Shutoff Devices for
Hot Water Supply Systems, ANSI Z21.22 and the Standard CAN1-4.4 Temperature, Pressure, Temperature and
Pressure Relief Valves and Vacuum Relief Valves . The combination temperature and pressure relief valve must
be marked with a maximum set pressure not to exceed the maximum working pressure of the water heater. The
combination temperature and pressure relief valve must also have an hourly rated temperature steam BTU
discharge capacity not less than the hourly rating of the water heater/storage unit. The supplied combination
temperature and pressure relief valve, when properly installed and unrestricted, will discharge the maximum
input produced by a 250°F (
121 °C) collector supply temperature. A lower collector supply temperature will
reduce the input required to be discharged in the event of excessive potable water temperatures.
Install the combination temperature and pressure relief valve into the side opening provided and marked for this
purpose on the water heater/storage unit.
Some models may already be equipped or supplied with a combination temperature and pressure relief valve.
Verify that the combination temperature and pressure relief valve complies with local codes. If the combination
temperature and pressure relief valve does not comply with local codes, replace it with one that does.
Install a discharge line so that water discharged from the combination temperature and pressure relief valve will
exit within six (6) inches above, or any distance below the structural floor and cannot contact any live electrical
part. The discharge line is to be installed to allow for complete drainage of both the temperature and pressure
relief valve and the discharge line. The discharge opening must not be subjected to blockage or freezing.
DO
NOT thread, plug, or cap the discharge line. It is recommended that a minimum clearance of four (4) inches be
provided on the side of the water heater/storage unit for servicing and maintenance of the combination
temperature and pressure relief valve
Do not place a valve between the combination temperature and pressure relief valve and the
tank!
