Before atteMptInG  to  Install  or  operate  the 

water heater.

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

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.
