on the thermostat, read the “Temperature Regulation” section
in this manual, see Figures 31 and 32.
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 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 (PILOT LIGHTING). It is adjustable and must
be reset to the desired temperature setting to reduce the risk of
scald injury. The mark (
) indicative of approximately 120°F
(49°C) is preferred starting point.
Turn the water temperature dial clockwise (
) 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.

Short repeated heating cycles caused by small hot water uses
can cause temperatures at the point of use to exceed the
thermostat setting by up to 30°F (16.7°C). If you experience this
type of use you should consider using lower temperature
settings to reduce scald hazards.
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 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, see
Figure 2 on page 6. Follow manufacturer’s instructions for
installation of the valves. Before changing the factory setting

DRAFT HOOD OPERATION
Check draft hood operation by performing a worst case
depressurization of the building. With all doors and windows
closed, and with all air handling equipment and exhaust fans
operating such as furnaces, clothes dryers, range hoods and
bathroom fans, a match flame should still be drawn into the
draft hood of the water heater with its burner firing. If the flame
is not drawn toward the draft hood, shut off the water heater and
make necessary air supply changes to correct.
CONDENSATION
Whenever the water heater is filled with cold water, some
condensate will form while the burner is on. A water heater may
appear to be leaking when in fact the water is condensation.
This usually happens when:
a. A new water heater is filled with cold water for the first time.
b. Burning gas produces water vapor in water heaters, particularly
high efficiency models where flue temperatures are lower.
