Pre-installation (continued)

Domestic water piping requirements

1.Install unions on all piping for easy removal of water heater.

2.Use dielectric unions or couplings to protect hot and cold water fittings from corrosion when connecting dissimilar materials such as copper and galvanized iron pipe.

3.When the supply pressure is higher than 70 PSIG, install a pressure reducing valve on cold water supply line to prevent water loss through T&P relief valve. A thermal expansion tank is also required.

4.If the water heater will replace a tankless coil in the boiler, discon- nect piping to coil or remove coil from boiler and replace with a cover plate. Allow water to drain from coil. Do not plug the tankless coil.

Plugging tankless coil inlet and outlet will result in severe personal injury, death or substantial property damage.

Studies have indicated that dangerous bacteria,

including legionella pneumophila, can form in

the potable water distribution system if certain minimum water temperatures are not maintained. Contact your local health department for more information.

Water heater operating restrictions

1. Read the operating limits under “Operating restrictions,” page 3.

Magnesium anode — The water heater is equipped with a magnesium sacrificial anode. The anode may erode over time, and should be inspected at least once annually, only by a qualified service technician. For installations with a likelihood of poor water conditions, the anode should be inspected at least every six months. Failure to comply could result in loss of protection by the anode, causing possible severe personal injury, death or substantial property damage due to water heater leakage.

The domestic water chloride concentration must not ex- ceed 200 ppm. High chloride concentrations can rapidly disintegrate the water heater’s protective anode.

Boiler water restrictions

1. Read the WARNINGS under “Boiler water restrictions,” page 3.

Hot Water Can Scald!

•Water heated to temperature for clothes washing, dish washing and other sanitizing needs can scald and cause permanent injury.

•Children, elderly, and infirm or physically handi- capped persons are more likely to be permanently injured by hot water. Never leave them unattended in bathtub or shower. Never allow small children to use a hot water tap or draw their own bath.

•If anyone using hot water in the building fits the above description, or if state laws or local codes require certain water temperatures at hot water taps, you must take special precau- tions:

•Use lowest possible temperature setting.

•Install some type of tempering device, such as an automatic mixing valve, at hot water tap or water heater.Automatic mixing valve must be selected and installed according to valve manufacturer’s recommendations and instructions.

•Water passing out of drain valves may be extremely hot. To avoid injury:

•Make sure all connections are tight.

•Direct water flow away from any person.

Protection must be taken against excessive tem- perature and pressure! — Installation of a tem- perature & pressure (T&P) relief valve (provided with water heater) and a thermostatic mixing valve (provided by installer) is required.
