WATER CONNECTIONS 
 
Note:  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.  The fittings at the cold water inlet and hot water 
outlet are dielectric waterway fittings with 3/4” NPT male thread.  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. 
 
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.
 
 
WARNING
 
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED 3/4” X 3/4” 
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE 
MANUFACTURER FROM ANY CLAIM, WHICH MIGHT RESULT FROM 
EXCESSIVE TEMPERATURE AND PRESSURES.
 
 
CAUTION
 
If sweat fittings are to be use, 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.
