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 code requirements, follow
NFPA-70 (current edition). In the absence of local codes, the
installation must comply with the latest 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 illustration in Figure 2.
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
•
Do not connect to non-potable water system.
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.
Products of this sort should not be stored near the heater. Also,
air which is brought in contact with the water heater should not
contain any of these chemicals. If necessary, uncontaminated air
should be obtained from remote or outside sources.
CIRCULATING PUMP
Field installed circulating pumps should be of all bronze
construction.
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 Pressure 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 temperature-pressure relief valve must
be installed directly into the fitting of the water heater designed
for the pressure relief valve. Install discharge piping so that any
discharge will exit only within 6 inches (15.2 cm) above, or at any
distance below the structural floor. Be certain that no contact is
made with any live electrical part. The discharge opening must not
