Water Connections continued-
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.
INSTALL TEMPERATURE AND PRESSURE RELIEF
VALVE (if not factory installed)
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.
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
