LIGHTING AND OPERATING INSTRUCTIONS

1. STOP! Read the safety information above on this label.

2. The gas valve must be shutt off by putting the ON/OFF

switch to position "0". Wait five (5) minutes to clear out

any gas. If you smell gas, STOP! Follow "B" in the safety

information above. If you do not smell gas, go to the

next step.

3. This water heater is equipped with a safety pilot burner

and an automatic ignition control system.

4. Set the ON/OFF switch (flip down cover plate on frontal

panel strip) marked I/0 to the I position. In this position,

the water heater is ready to use.

5. If the red LED indicator light (visible through the

peephole in the front panel strip) is flashing, this is a

warning that the batteries are less than 1.2 Volts and

will need to be replaced within the next couple of weeks.

Plan to have two D type 1.5 volt long-life (Alkaline)

batteries available for replacement.

6. Turn the hot water faucet on the minimum flow rate

required to activate the heater. The automatic ignition

system first ignites the safety pilot burner which then

ignites the main burner in about 4 seconds.

7. The pilot flame will extinguish 10-30 seconds after the

burners come on. The burners will remain on until the

hot water tap is turned off.

NOTE: On a first time initial installation, existence of air in

the gas supply line and in the water line may cause some

ignition delay. In that case, repeatedly open and close the

hot water tap in order to restart the ignition process until

all the air has been purged.

TO TURN OFF GAS TO APPLIANCE

Turn off the manual lever on the gas supply line to the

heater and set the ON/OFF switch to the OFF ( 0 ) position.

SETTING THE WATER TEMPERATURE

The AquaStar 125 X LP and 125 X NG water heaters have

a gas control that modulates burner input in response to

flow. Its purpose is to ensure that the hot water temperature

will remain steady, although the water flow demand might

vary (down to 1/2 gal/minute). To adjust the temperature

on your AquaStar, turn on a hot water faucet to its

maximum flow. At the water heater, turn the large knob

located beneath the main gas control on the front of the

heater all the way to the right (clockwise). See Fig 8. This

will produce a temperature rise of approximately 90°F at

flow rates between 0.5 and 2.0 gallons per minute. Given

that average incoming water temperatures are 50°F, this

heater will produce approximately 140°F water at these

flow rates. Turning the dial all the way to the left

(counterclockwise) will produce a temperature rise of

approximately 45°F for flow rates between 1.1 and 3.7

gallons per minute. It is safest to select a comfortable

temperature and not have to mix in cold water.

What is the best temperature setting? Because AquaStar

water heaters deliver endless hot water at the temperature

you have selected, there is no need to produce very hot

water and then mix in cold. It just does not make sense to

overheat water and then mix in cold to cool it off. You cannot

run out of hot water with an AquaStar, so set the dial for

the temperature you prefer . Note: 105 ° F is the maximum

recommended for a hot bath. The position you select on

the temperature adjustment knob will depend on the

temperature of the incoming water (50 ° F is average in the

U.S.). In warm weather regions where the incoming cold

water is generally warmer, or during the hot weather

months in some other areas a midway setting on the

temperature adjustment knob would produce a

temperature rise of about 70 ° F, giving an output of

approximately 120 ° F. At this setting, if it is still necessary,

one could mix a small amount of cold water in a shower

and have a comfortable shower at about 3 gallons/minute.

During the colder months, or in cold climate areas, it might

be necessary to set the control to the maximum position,

all the way clockwise to the right.

If you supply the AquaStar 125X, with preheated water

(i.e.) in a solar installation the unit could overheat. It will

then shut off on safety when the outlet temperature reaches

194 ° F. For this type of application, purchase a solar model

125B LPS or 125B NGS.

If the LED light is flashing, prepare to

shown

replace the batteries. Use two D cell

(1.5 volt) long life alkaline batteries.

To operate the heater, set the ON/OFF switch to position I.

The switch is located behind the flip down cover plate on

the front panel strip.

To shut down the gas to the heater, set the ON/OFF switch

to position 0
