Checking the Draft

WARNING
Do not touch vent.
Doing so can result in burns.
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 27). 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.

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 28. 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.
FIGURE 28.
Water Heater Stacking
Stacking occurs when a series of short draws of hot water (3
gallons or less) are taken from the water heater tank. This causes
increased cycling of the burner and can result in increased water
temperatures at the hot water outlet.
This water heater's temperature control has been designed to
accurately regulate the water temperature. However, under certain
operating conditions, the water temperature may temporarily
exceed the dial setting. Consequently, in addition to setting the
temperature no higher than 120°F, we recommend the installation
of a mixing valve or an anti-scald device in the hot water supply

line or at the point of use to further reduce the risk of scald injury.
These devices can be obtained from a plumbing service agency or
your retail supplier.

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
24. Follow manufacturer's instructions for installation of the valves.
Before changing the factory setting on the thermostat, see Figure
29. 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. 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 the
pilot position. It is adjustable and must be reset to the desired
temperature setting to reduce the risk of scald injury. The HOT
mark is indicative of approximately 120°F (49°C) and is the
preferred starting point. See Figure 29 on the next page. Some
states have a requirement for a lower setting.
Turn the water temperature dial clockwise (

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

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.
