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.
3. 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 steady streams of water flow through the
faucets, close them and check all water connections for possible
leaks.
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.
