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
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.
