MIXING VALVE USAGE:
Water heaters are intended to produce hot water. Water heated to
a temperature which will satisfy space heating, clothes washing,
dish washing, cleaning and other sanitizing needs can scald and
permanently injure you upon contact. Some people are more likely
to be permanently injured by hot water than others. These include
the elderly, children, the infi rm, or physically/developmentally
disabled. If anyone using hot water in your home fi ts into one of these
groups or if there is a Local/National code or state law requiring a
maximum water temperature at the hot water tap, then you must
take special precautions. In addition to using the lowest possible
temperature setting that satisfi es your hot water needs, a means
such as a
MIXING VALVE , should be used at the hot water taps
used by these people or at the water heater.
MIXING VALVES for reducing point of use temperature are available
and are to be set at a maximum of 125 degree F (52°C). Consult
a qualifi ed installer or service agency. Follow all manufacturer’s
Instructions for installation of these valves. Before changing the
factory setting on the thermostat, read the “Temperature Regulation”
section in this manual.
CONTAMINATED WATER
This water heater shall not be connected to any heating system(s)
or component(s) used with a non-potable water heating appliance.
Toxic chemicals, such as those used for boiler treatment shall not
be introduced into this system.
CIRCULATING PUMP
Field installed circulating pumps should be of all bronze
construction.
INSULATION BLANKETS
Insulation blankets are available to the general public for
external use on electric water heaters but are not necessary with
this product. The purpose of an insulation blanket is to reduce
the standby heat loss encountered with storage tank heaters.
Your water heater meets or exceeds the EPACT and ASHRAE/
IES 90.1 standards with respect to insulation and standby loss
requirements, making an insulation blanket unnecessary.
Should you choose to apply an insulation blanket to this heater,
you should follow these instructions below. Failure to follow
these instructions can result in fire, serious personal injury,
or death.
• Do not cover the temperature and pressure relief (T & P) valve
with an insulation blanket.
• Do not cover the instruction manual. Keep it on the side of the
water heater or nearby for future reference.
• Do obtain new warning and instruction labels for placement on
the blanket directly over the existing labels.
TEMPERATURE-PRESSURE RELIEF VALVE
This water heater is provided with a properly rated/sized and
certifi ed combination temperature - pressure relief valve by the
