Checking the Draft

After successfully lighting the water heater, allow the unit to operate
for 15 minutes and check the draft hood relief opening for proper
draft (Figure 26). Make sure all other appliances in the area are
operating and all doors are closed when performing the draft test.
Pass a match flame around the relief opening of the draft hood. A
steady flame drawn into the opening indicates proper draft.

FIGURE 26.
If the flame flutters or is blown out, combustion products are
escaping from the relief opening. If this occurs, do not operate the
water heater until proper adjustments or repairs are made to the
vent pipe system and/or air supply requirements.

Burner Flames

Inspect the burner flames through the viewport and compare
them to the drawing in Figure 27. A properly operating burner
should produce a soft blue flame. Blue tips with yellow inner
cones are satisfactory. The tips of the flame may have a slight
yellow tint. The flame should not be all yellow or have a sharp
blue-orange color. Contaminated air may cause an orange
colored flame. Contact a qualified technician if the flame is not
satisfactory.

to shut off, turn off the water heater's manual gas control valve
and call a qualified technician.

Water Temperature Regulation

Due to the nature of the typical gas water heater, the water
temperature in certain situations may vary up to 30°F (16.7 °C)
higher or lower at the point of use such as, bathtubs, showers,
sink, etc.
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 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. See Figure 23. Follow
manufacturer's instructions for installation of the valves. Before
changing the factory setting on the thermostat, see Figure 28.
Using the lowest hot water temperature that meets your needs
will also provide the most energy efficient operation of the water
heater.
Never allow small children to use a hot water tap, or to draw
their own bath water.
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 to reduce the risk of scald injury. The
mark is indicative of approximately 120°F (49°C) and is the
preferred starting point. See Figure 28 on the next page. Some
states have a requirement for a lower setting.

Should overheating occur or the gas supply fail to shut off, turn
off the manual gas control valve to the appliance.
