Operating instructions

Aviano at Desert Ridge
Due to the nature of the typical gas water heater, the water temperature
in certain situations may vary up to 30P (16.7 CO)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°C) 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.
Feel water before bathing or
showering.
Temperature limiting valves are
available.
Read instruction manual for safe
temperature setting.
HoneR 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 or state law requiring a certain
temperature water at the hot water tap, then you must take special
precautions. In additlon 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. Follow manufacturer's instructions for
installation of the valves. Before changing the factory setting on the
thermostat, read the "Temperature Regulation" section in this manual,
see Figures 14 and 15.
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.
MQIE; 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
(A) indicative of approximately 120°F (49°C) is preferred starting
point. Some States have a requirement for a lower setting.
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.

Check draft hood operation by performing a worst case depressurization

handing equipment and exhauslfans operating such as furnaces, clothes
dryers, range hoods and bathroom fans, a match flame should still be
drewn into the drafl hood of the water heater with its bumerfiring. If the
flame is not drawn toward the draft hood, shut off water heater and
make necessary air supply changes to correct.
will form while the bumer Is on. A water healer may appear to be leaking
when in fact the water is condensatlon. This usuelly 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 efflciency models where flue temperatures are lower.
c. Large amounts of hot water are used in a short time and the refill
water in the tank is very cold.
Moisture from the products of combustion condense on the oooIer tank
sllfaces and form drops of water which may fall onto the burner or
other hot surfaces to produce a 'slzzling" or "frying" noise.
Excessive condensation can cause pilot outage due to water running
down the flue lube onto the main bumer and putting out the pilot.
