OPERATING INSTRUCTIONS

Before operating the heater, make sure that the system is filled with water.

Open the cold water inlet supply to the heater fully. Open a hot water faucet to permit the water to fill the heater and the piping and to eliminate the air trapped in the system Close the hot water faucet after the water flows freely and all the air has escaped from the system. The water heater is now ready to operate.

FOR YOUR SAFETY READ BEFORE OPERATING YOUR HOT WATER HEATER

Warning: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life.

A.This appliance is equipped with electronic ignition for lighting the pilot and main burners. When turning the heater on, follow these instructions exactly.

B.Before operating the unit, set the On/Off switch to the On (I) position. The On/Off switch is located behind the flip-down coverplate on the front panel strip. Smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

WHAT TO DO IF YOU SMELL GAS

-Do not try to light any appliance.

-Do not touch any electric switch; do not use any phone in your building.

-Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

-If you cannot reach your gas supplier, call the fire department.

C.Use only your hand to push in the on/off control button. Never use tools. Follow these instructions exactly. If control button is jammed, close the gas supply and call a qualified service technician. Attempted forceful repair may result in a fire or explosion.

D.Do not use this appliance if any part has been under water. Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has been under water.

LIGHTING AND OPERATING INSTRUCTIONS

1.STOP! Read the safety information on the front panel of the heater.

2.The gas valve must be turned off by putting the On/Off switch to position “O” (see fig. 12). Wait five (5) minutes to clear out any gas. If you smell gas, STOP! Follow “B” in the safety information above. If you don’t smell gas, go to 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 front panel strip) marked I/O to the I position. In this position the water heater is ready to use.

5.Verify that the power supply to the appliance is turned on.

6.Turn the hot water faucet on to the minimum flow 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. The power exhaust will then activate.

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 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, see Fig. 11.

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.

SETTING THE WATER TEMPERATURE

The AquaStar 125FX LP and 125FX 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 demand for water flow 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 AquaStar, turn the large knob located beneath the main gas controls on the front of the heater all the way to the right (clockwise). See Fig 12. This will produce a temperature rise of approximately 90°F at flow rates between .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 1.0 and 4.0 gallons per minute. This will result in a higher flow rate, but at cooler temperatures. Turning the dial to locations in
