2) Take measurements for pipe. Cut and thread pipe not 

 threaded. 



3) Tap main water line with a tee. 



4) Make all connections. 



Note: Cold water must enter at the

drawn off at the top. Remember, also, 



that the bottom connection from water 



back must enter tank at the bottom, and 



the top connection must enter the tank 



several feet above the bottom and at a 



point above the back so the water will rise 



on being heated and will have proper circu- 

 lation.
