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 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.

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.

Toxic Chemical Hazard

• 

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
