INSTALLATION

REQUIRED ABILITY

Installation and service of this water heater requires ability equivalent 

to  that  of  a  qualified  installer  or  service  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 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 illustrations on page 7.

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 

and are to be set at a maximum of 120 degree F. 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.

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
