Lighting Instructions

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

2.The Gas valve must be turned off by sliding the gas valve button ( ) to the far left under the OFF () mark.

3.Wait five (5) minutes to clear out any gas. If you smell gas, STOP! Follow “B” in the safety information above on this plate. If you don’t smell gas, go to next step.

4.The pilot burner is located behind the peephole in the front center of the jacket directly below the lighting instructions on the front panel of the heater.

5.Slide the gas valve button to the right, to the pilot position ( ).

6.Fully depress gas valve button ( )and light pilot by

pressing hard on pilot igniter button ( ). This step may have to be repeated.

7.Observe the pilot flame through the peephole. The gas valve button should be held down at least 10 seconds with pilot burning. When the gas valve button is released, the pilot should continue to burn.

-If the gas valve button does not pop up when released, stop and immediately call your service technician or gas supplier.

-If pilot does not stay lit, repeat steps 1 through 7.

-If pilot will not stay lit after several tries, slide the gas valve button to the left, under the OFF () mark and call service technician or gas supplier.

8.When the pilot remains on, slide the gas valve button to the right, to the ON ( ) position. The heater will now fire when water is drawn at a rate of 1/2 gallon or more per minute.

NOTE: If main burner should fail to ignite, make sure pilot is burning. If not, repeat lighting steps 1 through 7.

TO TURN OFF GAS TO APPLIANCE

Slide the gas valve button ( ) to the far left, under the OFF ( ) mark and close the heaters individual shut-off valve.

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.). If you plan to supply the AquaStar 38 B, with preheated water (i.e.) solar installation, the unit could overheat. It will then shut off on safety when the outlet temperature reaches 185°F. For a lower temperature rise, the heater can be set for minimum burner output by sliding the gas valve control to the pilot setting symbol ( ).

SETTING THE WATER TEMPERATURE

To adjust the temperature on your AquaStar, turn on a hot water faucet to its maximum flow. At the water heater, turn the large temperature adjustment knob located beneath the main gas controls on the front of the heater all the way to the right (clockwise). See Fig 6. This will produce a temperature rise of approximately 90oF at a flow rate of .5 gallons per minute (gpm). Turning the dial all the way to the left (counterclockwise) will increase the water flowing through the heater, and will produce a temperature rise of approximately 45oF at a flow rate of

1.3gpm. Given that average incoming water temperatures are 50oF, this heater will produce water between 140o and 95o at these flow rates. Thus one can obtain a higher flow rate, but at cooler temperatures.
