INSTALL TEMPERATURE AND PRESSURE RELIEF 
VALVE (if not factory installed) 

INSTRUCTIONS FOR POTABLE CONNECTIONS 

1.  BEFORE PROCEEDING WITH THE INSTALLATION, 

CLOSE THE MAIN WATER SUPPLY VALVE.  After 
shutting off the main water supply, open a faucet to relieve the 
water line pressure to prevent any water from leaking out of 
the pipes while making the water connections to the water 
heater.  After the pressure has been relieved, close the faucet.  
The COLD water inlet and HOT water outlet are identified 
on the top of the water heater.  Make the proper plumbing 
connections between the water heater and the plumbing 
system to the house.  Install a shut-off valve in the cold water 
supply line. 

2.  If this water heater is installed in a closed water supply 

system, such as one having a back-flow preventer in the cold 
water supply, provisions must be made to control thermal 
expansion.  DO NOT operate this water heater in a closed 
system without provisions for controlling thermal expansion.  
Warranties do not cover damages from thermal expansions 
such as pressure bulges and/or deformities.  A properly sized 
expansion tank will alleviate most problems.  Your water 
supplier or local plumbing inspector should be contacted on 
how to control this situation. 

3.  After installation of the water lines, open the main water 

supply valve and fill the water heater.  While the water heater 
is filling, open several hot water faucets to allow air to escape 
from the water system.  When steady  

WARNING

 

Temperature and pressure relief valve discharge piping must be 
piped near the floor to eliminate potential of severe burns.  Do 
not pipe in any area where freezing could occur.  Do not install 
any shut-off valves, plugs or caps to the temperature and 
pressure relief valve or piping.
