Water Connections

 

 

NOTE:  BEFORE PROCEEDING WITH THE INSTALLATION, CLOSE THE 
MAIN WATER SUPPLY VALVE. 

 
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 line connects to the inlet 
nipple at the base of the water heater.  The hot water outlet line connects to 
the nipple on top of the water heater. The fittings at the cold water inlet and 
hot water outlet are dielectric waterway fittings with tapered male threads.  
Make the proper plumbing connections between the water heater and the 
plumbing system in the structure.  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 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.  After a steady stream 
of water flows from 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.

 

CAUTION 

If sweat fittings are to be used, 

DO NOT

 apply heat to the nipples on 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.

 

IMPORTANT 

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