LATCHES – The latches allow easy access for servicing the water heater from the top. Simply remove the two latches for
servicing and re-latch upon completion. No tools are required to obtain access to the top of the water heater.
MIXING VALVE – This water heater is supplied with an ASSE approved mixing valve to reduce the potential for scald injury
when thermostat settings over 120˚F (49ºC) are used for dishwashers or other appliances. The mixing valve reduces the discharge
temperature by mixing cold and hot water in the branch supply lines. Refer to the instructions supplied with the mixing valve for
installation procedures and device specifications. The mixing valve is located inside the control compartment.
SCALDING WARNING
ASSE APPROVED MIXING DEVICE MUST BE INSTALLED
TO PROVIDE PROTECTION FROM SCALDING
This water heater can deliver scalding temperature water at any faucet in the system if installed without installing the
supplied ASSE mixing device. By setting the thermostat on this water heater to obtain an increased water temperature
without properly installing the supplied mixing device, you may create the potential for scald injury. To protect against
injury, the supplied ASSE approved mixing device (a device to limit the temperature of water to protect against scald injury
via mixing hot and cold water supply) must be properly installed in the water system. This valve will reduce point of
discharge temperature in branch supply lines.
TEMPERATURE AND PRESSURE RELIEF VALVE –
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 rating must not be less than the hourly rating of the water
heater
Install the combination temperature and pressure relief valve into the opening provided and marked for this
purpose on the water heater.
Note: Some models may already be equipped or supplied with an installed 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.
Follow the installation instructions above on this page
Install a discharge line so that water discharged from the combination temperature and pressure relief valve will
exit within 6 inches (15.2 cm) 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 combination
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 4 inches (10.2 cm) be provided on the side of the water heater 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!
