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

instantly resulting in severe injury ordeath.

HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which wilt 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 taw 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 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 manufacturer's instructions for installation of the valves. Before changing the factory setting on the thermostat See Figures 21 and 22.
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.
NOTE: Awater temperature range of
The thermostat of this water heater has been factory set at its lowest position. It is adjustable and must be reset to the desired temperature setting for energy efficient operation at the minimum water temperature setting that meets your hot water needs. To reduce the risk of scald injury, 120°F (49°C)is preferred starting point. Some states have a requirement for a lower setting.
Align the index bar on the thermostat with the desired water temperature as shown in Figure 21.
Turn the water temperature dial clockwise ( t'_ ) to increase the temperature, or counterclockwise ( _ ) to decrease the temperature.
Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.
