D. Water Temperature Adjustment thermostat is factory set at 125°F (51,7°C) or lower to reduce the risk of scalding injury If the water heater is going to have a set temperature above 120oF, it is recommended to use an ASSE 1017 rated mixing valve to avoid severe burns or death from scalding temperatures. Households with small children, disabled, or elderly persons may require a 120oF or lower temperature setting to prevent severe personal injury or death due to scalding.
If you suspect that your water is contaminated in any way, discontinue use of the appliance and contact an authorized technician or licensed professional. • Water pH between 6.5 and 8.5 • pH levels below 6.5 can cause an increase in the rate of corrosion. pH of 8.5 or higher can potentially cause lime scale build-up • Maintain water pH between 6.5 and 8.5. Check with litmus paper or have it chemically analyzed by a local water treatment company. • If the pH is not between 6.5 and 8.

Part 3 - Piping A. Plumbing It is mandatory that all plumbing be done in accordance with federal, local, and state plumbing codes and practices. Failure to properly install the water heater WILL VOID the warranty. It is also necessary to use both thread tape and pipe dope on all mechanical plumbing connections. Install unions on the hot and cold water connections to easily disconnect the water heater for servicing.
F. Scalding Do not thread a cap or plug into the relief valve or relief valve line under any circumstances! Explosion and property damage, serious injury, or death may result. To avoid water damage or scalding due to relief valve operation: • Discharge line must be connected to relief valve outlet and run to a safe place of disposal. Terminate the discharge line in a manner that will prevent possibility of severe burns or property damage should the relief valve discharge.
G. Filling the Heater When filling the water heater, open a hot water tap to release air in the tank and piping. The tank must be full of water before the heater is turned on. Failure to ensure the water heater is full before turning it on could result in damage to the water heater and other property damages. Such damages ARE NOT covered by water heater warranty. • Make certain that the field installed drain valve is completely closed. • Open the shut-off valve in the cold water supply line.
