After shutting the main water supply valve, 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 top of the water heater.  The fittings at the cold water inlet and 
hot water outlet are dielectric waterway fittings with 3/4” NPT tapered male 
threads.  Make the proper plumbing connections between the water heater 
and the plumbing system in the house.  Install a shut-off valve in the cold 
water supply line. 

 

 

 
If this water heater is installed in a closed water supply system, such as the 
one having a back-flow preventer in the cold water supply, provisions shall 
be made to control thermal expansion.  DO NOT operate this water heater in 
a closed system without provisions for controlling thermal expansion.  Your 
water supplier or local plumbing inspector should be contacted on how to 
control this situation. 
 
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 a steady stream 
of water flows through the faucets, close them and check all water 
connections for possible leaks.  NEVER OPERATE THE WATER HEATER 
WITHOUT FIRST BEING CERTAIN IT IS FILLED WITH WATER. 
 

If sweat fittings are to be used, DO NOT apply heat to the nipples on top 
of the water heater.  Sweat the tubing to the adapter before fitting the 
adapter to the water connections.  It is imperative that heat is not applied 
to the nipples containing a plastic liner. 

FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4” 
TEMPERATURE-PRESSURE RELIEF VALVE WILL RELEASE THE 
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM 
EXCESSIVE TEMPERATURE AND PRESSURES.
