Electrical Connections 

 
All electrical wiring and connections must be in accordance with the National 
Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical Code 
C22.1 (latest edition) and any local codes which may apply. The water heater 
must be electrically grounded. 
 
If a flexible line cord and plug is permitted by local code, then provide a (3) three 
wire grounding type receptacle within 6 feet (1.9 m) of the water heater and use 
the flexible cord provided. Do not plug the line cord into a receptacle that can 
have its power supply interrupted by a switch that is used to turn on and off 
lights. 
 
If wiring in conduit is required, remove the flexible line cord from the jacket and 
install a 1/2" electrical conduit connector and connect 110/120 volt power source.  
Connect the hot, neutral, and ground leads of the electrical supply to the 
corresponding locations that were connected to the flexible line cord.
