With electrical power supplied, the water heater will not freeze when the outside air temperature is as cold as –22°F (‐30°C) for indoor models or is as cold as –4° F (‐20°C) for outdoor models, when protected from direct wind exposure. Because of the “wind‐chill” effect, any wind or circula on of the air on the unit will reduce its ability to freeze protect. The unit may be drained manually. However, it is highly recommended that: • drain down solenoid valves are installed that will automa cally drain the unit if power is lost. These are available in a kit, J‐A105. • a surge protector with terminals is installed which allows the solenoid valves to operate if the unit is disabled due to a diagnos c code.

Page 29: How To Set The Temperature
How to Set the Temperature This water heater requires a minimum flow rate to operate. This rate can be found on the specifica on page in this manual. In some cases when you are not ge ng hot water or if the water alternates between hot and cold, it is due to the water flow being below or close to the minimum flow rate. Increasing the flow rate should resolve these problems in these cases. If you are experiencing issues with higher temperature se ngs, then reduce the temperature se ng. Selec ng a temperature closer to that which is actually used at the faucet will increase the amount of hot water being delivered to the faucet, due to less cold water mixing at the fixture. Hot water can be dangerous, especially for infants or children, the elderly, DANGER or infirm. There is hot water scald poten al if the thermostat is set too high. Water temperatures over 125° F (52° C) can cause severe burns or scalding resul ng in death. Hot water can cause first degree burns with exposure for as li le as: 3 seconds at 140° F (60° C) 20 seconds at 130° F (54° C) 8 minutes at 120° F (49° C) Test the temperature of the water before placing a child in the bath or shower.
