injured by hot water than others. These include the
elderly, children, the infirm, or physically/ developmentally
disabled. If anyone using hot water in you home fits into
one of these groups, or if there is a local 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 satisfies
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˚F.
Consult a qualified 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) 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 (T&P) Valve
with an insulation blanket.
Do not over the instruction manual. Keep it on the side
of the water heater or nearby for future reference.
Obtain new warning and instruction labels for placement
on the blanket directly over the existing labels.
TEMPERATURE AND PRESSURE RELIEF VALVE
This water heater is provided with a properly rated/ sized
and certified combination Temperature and Pressure
Relief Valve. The valve is certified by a nationally
recognized testing laboratory that maintains periodic
inspection of production of listed equipment of materials
as meeting the requirements for Relief Valves for Hot
Water Supply Systems, ANSI Z21.22 · CSA 4.4, and the
code requirements of ASME.
If replaced, the new valve must meet the requirements of
local codes, but not less than a combination Temperature
and Pressure Relief Valve rated/ sized and certified as
indicated in the above paragraph. The new valve must be
marked with a maximum set pressure not to exceed the
marked hydrostatic working pressure of the water heater
(150 psi = 1,035 kPa) and a discharge capacity not less
than the water heater BTU/ hr or KW input rate as shown
on the water heater’s model rating plate.
For safe operation of the water heater, the temperature
and pressure relief valve must not be removed from its
designated opening, nor plugged. The T&P Valve must
be installed directly into the fitting of the water heater
designated for the relief valve. Install the discharge piping
so that any discharge will exit only within 6 inches above,
or at any distance below, the structural floor. Be certain
that no contact is made with any live electrical part. The
use of more than four elbows can cause restriction and
reduce the discharge capacity of the valve.
No valve or other obstruction is to be placed between the
relief valve and the tank. Do not connect discharge piping
directly to the drain unless a 6-inch air gap is provided. To
prevent bodily injury, hazard to life, or property damage,
the relief valve must be allowed to discharge water in
adequate quantities should circumstances demand. If the
discharge pipe is not connected to a drain or other suitable
means, the water flow may cause property damage.

WARNING
TOXIC CHEMICAL HAZARD
Do not connect to non-potable water system.
WARNING
EXPLOSION HAZARD
Temperature and Pressure Relief
Valve must comply with ANSI
Z21.22 and ASME code.
Properly-sized Temperature and
Pressure Relief Valve must be
installed in opening provided.
Failure to install relief valve can
result in overheating and excessive
tank pressure.
Failure to follow these instructions
can cause serious injury or death.
