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 7 and 8.
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.
INSTALLATION
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.
•
Do not connect to non-potable water 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 certified combination temperature - pressure relief valve
by the manufacturer. 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
