Burner Flames
Inspect the burner flames through the viewport and
compare them to the drawings in Figure 19. 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.
Emergency Shut Down
IMPORTANT:
Should overheating occur or the gas supply
fails to shut off, turn off the heater’s manual gas control
valve and the electrical power. Call a qualified technician.
Water Temperature Regulation
Water temperature over 125°F can cause
severe burns instantly or death from scalds.
Children, disabled and elderly are at highest
risk of being scalded.
Feel water before bathing or showering.
Temperature limiting valves are available.
WARNING
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 14. Follow manufacturer’s
instructions for installation of the valves. Before changing
the factory setting on the thermostat see Figure 21. 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 its lowest position. It is adjustable and must be reset to
the desired temperature setting to reduce the risk of scald
injury. The electronic control display temperature should
be set at approximately 120°F (49°C) and this is the pre-
ferred starting point. Some states have a requirement for a
lower setting. If you need hotter water, follow directions for
temperature adjustment, but beware of the warnings in this
section, see Figure 20.
Figure 20
Pressing the “COOLER” button decreases temperature
and pressing the “HOTTER” button increases the
temperature.
To avoid any unintentional changes in water temperature
settings, the control has a tamper resistant feature
for changing the temperature setting. To change the
temperature setting follow these instructions:
1. “Wake Up” the temperature indicators by holding down
both “COOLER” and “HOTTER” temperature adjust-
ment buttons at the same time for one second (See
Figure 21). The display will light up. The display will
only remain on for 30 seconds if no further buttons are
pressed. After 30 seconds the control will go back to
“Sleep” mode.
2. Release both of the temperature adjustment buttons.
A. To decrease the temperature press and release the
“
COOLER
” button until the desired setting is reached.
