InstALLAtIon
rEQuIrEd ABILIty
Installation and service of this water heater requires ability equivalent
to that of a qualified agency (page 2) in the field involved. Plumbing
and electrical work is required.
GEnErAL
The installation must conform with these instructions and the
local code authority having jurisdiction and the requirements of
the power company. In the absence of local codes, the installation
must comply with the current editions of the National Electrical
Code, NFPA 70 or the Canadian Electrical Code CSA C22.1.
The National Electrical Code may be ordered from: National Fire
Protection Association, 1 Batterymarch Park, Quincy, MA 02269.
The Canadian Electrical Code is available from the Canadian
Standards Association, 8501 East Pleasant Valley Road,
Cleveland, OH 44131.
Note:
To comply with NSF Standard 5 installation requirements
the bottom of the water heater must be sealed to the floor with a
silicone based sealant or elevated 6 inches above the floor.
Do
not
test electrical system before heater is filled with water, follow
the START UP procedure in the OPERATION section of this manual.
The principal components of the heater are identified in the
Features and Components illustrations on pages 6 and 7.
Water temperature over 125°F (52°C)
can cause severe burns instantly
resulting in severe injury or death.
Children, the elderly and the
physically or mentally disabled are at
highest risk for scald injury.
Feel water before bathing or
showering.
Temperature limiting devices such as
mixing valves must be installed
when required by codes and to
ensure safe temperatures at fixtures.
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 infirm, or physically/developmentally
disabled. If anyone using hot water in your 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. 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) 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.
