Checking the Draft
WARNING
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 22). 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 22.
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 23. 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.

Burn Hazard
Do not touch vent.
Doing so can result in burns.

Emergency Shut Down
IMPORTANT: Should overheating occur or the gas supply fails
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 18. Follow
manufacturer's instructions for installation of the valves. Before
changing the factory setting on the thermostat, see Figure 24A.
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 is adjusted to the pilot position when it is shipped
from the factory. Water temperature can be regulated by moving
the temperature dial to the preferred setting. The preferred
starting point is 120°F at the "HOT" setting. Align the knob with
the desired water temperature as shown in Figure 24A. There is
a hot water scald potential if the thermostat is set too high.
NOTE: Temperatures shown on the gas control valve/thermostat
are approximates. The actual temperature of the heated water
may vary.

Water temperature over 125°F (52°C)
can cause servere 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.
Never leave a child or handicapped
