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.
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 1.
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.
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.
InstallatIon reQuIreMents
Before changing the factory setting on the thermostat, read the
"Temperature Regulation" section in this manual.
contaMInated Water
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.
teMperature-pressure relIef ValVe
This water heater is provided with a properly rated/sized and certified
combination Temperature-Pressure Relief valve (T&P valve) by the
manufacturer. The T&P 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 • CSA4.4, and
the code requirements of ASME.
If replaced, the new T&P valve must meet the requirements
of local codes, but not less than a combination Temperature-
Pressure Relief valve rated/sized and certified as indicated in
Some
the above paragraph. The new T&P 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 label.
note: In addition to the factory installed Temperature-Pressure
Relief valve on the water heater, each remote storage tank that
may be installed and piped to a water heating appliance must also
have its own properly sized, rated and approved Temperature-
Pressure Relief valve installed. Call the toll free technical
support phone number listed on the back cover of this manual
for technical assistance in sizing a Temperature-Pressure Relief
valve for remote storage tanks.
