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.
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.
Water temperature over 125°F (52°0) can cause severe burns
instantly resulting in severe injury or death.
Children, the elderly and the physically or mentally disabled are at highest risk for scald injury
Fee] water before bathing or showering.
Temperature limiting valves are available
Read instruction manual for safe temperature setting
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,
changing the factory setting on the thermostat, read the Temperature Regulation section in this manual, 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: A water 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 to reduce the risk of scald injury. The mark (A) indicative of approximately 120°F (49°0) is preferred starting point. Some states have a requirement for a lower setting.
Turn the water temperature dial clockwise ( t'_ ) to decrease the temperature, or counterclockwise ( _ ) to increase the temperature.
Should overheating occur or the gas supply fail to shut off, turn off the manual gas control valve to the appliance.

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 at plumbing supply or hardware stores. Follow manufacturer's instructions for installation of the valves. Before
