Temperature Regulation

Due to the nature of the typical water heater, the water temperature in certain situations may vary up to 30°F (16.7 °C) higher or lower at the point of use such as, bathtubs, showers, sink, etc.

Any water heater’s intended purpose is to heat water. Hot water is needed for cleansing, cleaning, and sanitizing (bodies, dishes, clothing). Untempered hot water can present a scald hazard. Depending on the time element, and the people involved (adults, children, elderly, infirm, etc.) scalding may occur at different temperatures.

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact. Some people are more likely to be permanently injured by hot water than others. These include the elderly, children, the infirm, or physically/mentally handicapped. If anyone using hot water in your home fits into one of these groups or if there is a local code or state law requiring a certain temperature water at the hot water tap, then you must take special precautions. In addition to using the lowest possible temperature setting that satisfies your hot water needs, a means such as a mixing valve, shall be used at the hot water taps used by these people or at the water heater. Mixing valves are available from your local plumbing contractor. Follow manufacturer’s instructions for installation of the valves. Before changing the factory setting on the thermostat, read the “Temperature Regulation” section in this manual.

HOT WATER TEMPERATURES DESIRED FOR AUTOMATIC DISHWASHERANDLAUNDRYUSECANCAUSESCALDSRESULTING IN SERIOUS PERSONAL INJURY AND/OR DEATH. THE TEMPERATURE AT WHICH INJURY OCCURS VARIES WITH THE PERSON’S AGE AND THE TIME OF THE EXPOSURE. THE SLOWER RESPONSE TIME OF CHILDREN, AGED OR DISABLED PERSONS INCREASES THE HAZARDS TO THEM. NEVER ALLOW SMALL CHILDREN TO USE A HOT WATER TAP, OR TO DRAW THEIR OWN BATH WATER. NEVER LEAVE A CHILD OR DISABLED PERSON UNATTENDEDINABATHTUBORSHOWER.

It is recommended that lower water temperatures be used to avoid the risk of scalding. It is further recommended, in all cases, that the water temperature thermostat be set for the lowest temperature which satisfies your hot water needs, see Figure 11. This will also provide the most energy efficient operation of the water heater. The Thermostat has been factory set between LO an HI which approximates 120°F (49°C) unless specified differently by state requirements.

TEMPERATURE ADJUSTMENT

To change the temperature setting:

NOTE:

1.Turn off the heater electrical supply. Do not attempt to adjust thermostat with power on.

2.Remove the thermostat outer door and fold away the insulation from the thermostat. Do not remove the plastic personnel protector covering the thermostat.

3.Using a flat tip screwdriver, rotate the adjustment knob to the desired temperature setting.

4.Fold the insulation back in place, replace the outer door and turn on heater electrical supply.

LO - Setting, approximately 95°F (35°C) is recommended for vacations or extended periods of no hot water.

HI - Is setting for the maximum hot water usage approximately 140°F (60°C), which can be supplied by the water heater.

TEMPERATURE SETTINGS

It is recommended that the dial be set lower whenever possible.

Temperature		Time to Produce 2nd & 3rd
Setting		Degree Burns on Adult Skin

160°F (71°C)		About 1/2 second
150°F (66°C)		About 1-1/2 seconds
140°F (60°C)		Less than 5 seconds
130°F (54°C)		About 30 seconds
120°F (49°C)		More than 5 minutes
