SECTION V: WATER CONNECTIONS
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.
Hydrogen gas can be produced in an operating water heater that has not had water drawn from the tank for a long
period of time (generally two weeks or more). HYDROGEN GAS IS EXTREMELY FLAMMABLE. To prevent
the possibility of injury under these conditions, we recommend the hot water faucet to be open for several minutes at
the kitchen sink before you use any electrical appliance, which is connected to the hot water system. If hydrogen is
present, there will be an unusual sound such as air escaping through the pipes as hot water begins to flow. Do not
smoke or have open flame near the faucet at the time it is open.
Keep clear of the combination 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.
CAUTION
If sweat fittings are to be used, DO NOT apply heat to the nipples in front or side 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.
INSTRUCTIONS FOR 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.
The COLD water inlet and HOT water outlet are identified on 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 the 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 expansion such as pressure bulges and/or deformities.
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 a
steady stream of water flows through the faucets, close them and check all water connections for possible
leaks.
4. Never operate the water heater without first being certain it is filled with water.
