QualifiCations

Qualified Installer or Service Agency

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

this manual first and then the entire manual carefully. If you 

don’t follow the 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 the 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 the 

proper operation of the water heater and your safety. Since 

we cannot put everything on the first few pages, re AD THe 

enTIre MAnUAl be FOre ATTeMPTInG TO InSTAll Or 

OPerATe THe WATer HeATer.

2.  The installation must conform with these instructions and the 

local code authority having jurisdiction. In the absence of local 

codes, the installation must comply with the current editions of 

the national Fuel Gas Code, AnSI Z223.1/nFPA 54 or CAn/

CSA-b149.1 the natural Gas and Propane Installation Code. 

All  documents  are  available  from  the  Canadian  Standards 

Association, 8501 east Pleasant Valley road, Cleveland, OH 

44131. nFPA documents are also available from the national Fire 

Protection Association, 1 batterymarch Park, quincy, MA 02269.

3.  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.

4.  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.
examine the location to ensure the water heater complies with 

the “locating the Water Heater” section in this manual.

5.  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.
