SECTION V
WATER CONNECTIONS
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.
WARNING
FAILURE TO INSTALL AND MAINTAIN A NEW, LISTED
TEMPERATURE AND PRESSURE RELIEF VALVE WILL RELEASE THE
MANUFACTURER FROM ANY CLAIM WHICH MIGHT RESULT FROM
EXCESSIVE TEMPERATURE AND PRESSURES.
Keep clear of the temperature and pressure relief valve discharge line
outlet. The discharge may be hot enough to cause scald injury. The
water is under pressure and may splash.
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.
