Temperature Regulation
Due to the nature of the typical gas water heater, the water
temperature incertain situationsmay vary upto 30F° (16.7 C°)
higheror lower at the pointof use such as, bathtubs, showers,
sink, etc.
Water temperature over 125°F
(52°C) can cause severe burns
instantJy resulting in severe injury
or death.
Children, the elderly, and the
physically or mentally disabled
are at highest risk forscald injury.
Feel water before bathing or
showering.
Temperature limiting valves are
available
Read instruction manual for safe
temperature setting
Ho'n'ER WATER CAN SCALD: Water heaters are intended to
produce hot water. V_ter 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 physicelly/mentally handicapped. If anyone using
hot water in your home fits into one of these groups or ifthere is
a local cede 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
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 childrento 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 120°F-140°F (49°C-60°C)
is recommended by most dishwasher manufacturers.
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 atthe 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 ( f'_ ) to increase
the temperature, or counterclockwise ( _ ) to decrease the
temperature.
Should overheating occur or the gas supplyfail to shut off, turn
off the manual gas control valve to the appliance.
