American Water Heater 317994-002 Manual De Usuario

22

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.

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 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.

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 Figures 20 and 

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, see Figure 20. 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.

Press 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.

 

B. To increase the temperature press and release the 

“

HOTTER

”    button until the desired setting is reached.

NOTE: Should overheating occur or the gas supply fail 

to shut off, turn off the manual gas control valve to the 

appliance.

NOTE:  During low demand periods when hot water is not 

being used, a lower thermostat setting will reduce energy
