thank You for purchasing this water heater.  Properly installed and 

maintained, it should give you years of trouble free service.
Abbreviations Found In This Instruction Manual:

•  CSA - Canadian Standards Association

•  ANSI - American National Standards Institute

•  NFPA - National Fire Protection Association

•  ASME - American Society of Mechanical Engineers

•  AHRI - Air Conditioning, Heating and Refrigeration Institute

•  UL - Underwriters Laboratories Inc.

This  gas-fired  water  heater  is  design  certified  by  Underwriters

Laboratories Inc. under American National Standard/CSA Standard 

for Gas Water Heaters ANSI Z21.10.3 • CSA 4.3 (current edition).

Installation and service of this water heater requires ability equivalent 

to that of a Qualified Agency (as defined by ANSI below) in the field

involved. Installation skills such as plumbing, air supply, venting, 

gas supply and electrical supply are required in addition to electrical 

testing skills when performing service.
ansI Z223.1 2006 sec. 3.3.83: “Qualified Agency” - “Any individual,

firm,  corporation  or  company  that  either  in  person  or  through  a

representative is engaged in and is responsible for (a) the installation,

testing or replacement of gas piping or (b) the connection, installation,

testing, repair or servicing of appliances and equipment; that is 

experienced in such work; that is familiar with all precautions required; 

and that has complied with all the requirements of the authority 

having jurisdiction.”
If you are not qualified (as defined by ANSI above) and licensed or

certified as required by authority having jurisdiction to perform a given

task do not attempt to perform any of the procedures described in this 

manual. If you do not understand the instructions given in this manual 

do not attempt to perform any procedures outlined in this manual. 

1.  Read “General Safety Information” section, page 3 and 4 of this manual

first and then entire manual carefully. If you don’t follow safety rules,

the water heater will not operate properly. It could cause DEATH, 

SERIOUS BODILY INJURY AND/OR PROPERTY DAMAGE.

  This manual contains instructions for installation, operation, 

and maintenance of the gas-fired water heater. It also contains

warnings throughout the manual that you must read and be 

aware of. All warnings and all instructions are essential to proper 

operation of the water heater and your safety. Since we cannot 

put everything on the first few pages,

2.  The installation must conform with these instructions and local 

code authority having jurisdiction. In absence of local codes, 

installation must comply with current editions of the National Fuel 

Gas Code, ANSI Z223.1/NFPA 54 and National Electrical Code, 

NFPA 70. All documents are available from Canadian Standards 

Association, 8501 East Pleasant Valley Road, Cleveland, OH 

44131. NFPA documents are also available from National Fire 

Protection Association, 1 Batterymarch Park, Quincy, MA 02269.

3.  The water heater when installed must be grounded in accordance 

with the local codes, or in the absence of local codes: the National 

Electrical Code (NFPA 70).

4.  If after reading this manual you have any questions or do not 

understand any portion of the instructions, call the local gas utility or 

the manufacturer whose name appears on the rating plate.

5.  Carefully plan the place where you are going to put the water heater.  

Correct combustion, vent action, and vent pipe installation are 

very important in preventing death from possible carbon monoxide 

poisoning and fires, see Figures 1 and 2.

  Examine the location to ensure the water heater complies with the 

“Locating the New Water Heater” section in this manual.

6.  For California installation this water heater must be braced, 

anchored, or strapped to avoid falling or moving during an 

earthquake. See instructions for correct installation procedures. 

Instructions may be obtained from California Office of the State

Architect, 400 P Street, Sacramento, CA 95814.

7.  Massachusetts Code requires this water heater to be installed in 

accordance with Massachusetts 248-CMR 2.00: State Plumbing 

Code and 248-CMR 5.00.

8.  Complies with SCAQMD rule #1146 and districts having equivalent 

NOx requirements.
