SERVICE AND ADJUSTMENT
Temperature Regulation
HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy 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, some type of tempering device, such as a mixing valve, should be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores. Follow manufacturers instructions for installation of the valves, Before changing the factory setting of the thermostat see Temperature Settings table at right.
Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or handicapped person unattended in a bathtub or shower.
Thermostats
The thermostats of this water heater have been factory set at a position which approximates 120°F (49°C), to reduce the risk of scald injury.
The upper thermostat is factory set at a position which approximates 120°F (49°C), and is adjustable if a different water temperature is desired. Read all warnings in this manual and on the water heating before proceeding.
ADJUSTABLE UPPER THERMOSTAT
FIGURE 26.
The lower thermostat is factory set at a position which approximates 120°F (49°C), and is adjustable if a different water temperature is desired. Read all warnings in this manual and on the water heating before proceeding.
