IMPORTANT SAFETY INFORMATION READ ALL INSTRUCTIONS BEFORE USING.

!DANGER!

WATER TEMPERATURE SETTING

Safety and energy conservation are factors to be considered when selecting the water temperature setting of a water heater’s remote control. Water temperatures above 125°F (52°C) can cause severe burns or death from scalding. Be sure to read and follow the warnings outlined on the label pictured below.

Notice:

The chart shown above may be used as a guide in determining the proper water temperature for your home.

!DANGER: Households with small children, disabled or elderly persons may require a 120°F (49°C) or lower temperature setting to prevent contact with “HOT” water.

Maximum water temperature occurs while burner is on. To find water temperature being delivered, turn on a hot water faucet and place a thermometer in the water stream and read the thermometer. (See page 27 & 28 for more details.)

The temperature of the water at the outlet of the water heater can be regulated by setting the temperature on Remote Control. The remote control was set at 100°F (38°C) before it was shipped from the factory.

The diagram to the bottom left illustrates the Remote Control and how to adjust the water temperature.

Notice: The factory setting allows operating temperatures between 100°F (38°C) and 120°F (49°C). Temperatures of up to 140°F (60°C) can be achieved with the MAIN (UMC-117) remote control and a dip switch adjustment. Only qualified service personnel should perform this adjustment. Only factory authorized remote control(s) should be used.

Notice: When this water heater is supplying general purpose hot water requirements for use by individuals, a thermostatically controlled mixing valve for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.

*Temperatures above 120°F (49°C) can be achieved by adjusting the dip switch. See page 35 for dip switch adjustment.
