GSW 319594-000 manual approximately 21C 70F when shipped from factory, Gas Control/Thermostat

CAUTION:

Read before proceeding. If you do not follow these instructions exactly, a fire or explosion may result, causing property damage, per- sonal injury or loss of life.

Gas Control/Thermostat

Alternatively, this heater may be equipped with the White- Rodgers Intelli-VentTMgas control/thermostat and a hot-sur- face igniter. This control is a combination gas valve, ther- mostat and ignition controller for use on this power vented water heater. The valve contains a microcomputer that supervises the ignition sequence and monitors the temper- ature settings and operation of the heater. The computer also monitors the flammable vapour safety features of this heater.

This heater is equipped with a White-Rodgers Silicon Nitride Igniter system that automatically ignites the burner. Do not attempt to light this heater manually with a match or flame-producing device.

Putting the Heater into Service

1.Turn the manual gas shut-off valve for the heater to the “ON” position.

2.Follow the Lighting Instructions (White-Rodgers) given on the side of the water heater and also depicted in this manual. See also “Gas Supply”, “Water Heater Operation” and “Sequence of Operation”.

3.Upon start up all the indicator lights on the front of the control will come on and then turn off. This indicates that the control has completed a self-diagnostic test and is ready for operation.

Note: If any of the indicator lights remain on, this indicates a system fault that needs correcting. See the “System Error Codes” and “Troubleshooting Guide (White-Rodgers)” for corrective action.

The temperature of the water can be selected by using the temperature adjustment buttons on the front of the gas con- trol (see Figure 25) as follows:

1.“Wake up” the temperature indicators by holding down both the “COOLER” and “HOTTER” temperature adjust- ment buttons at the same time for one second. One or two of the temperature indicators will light up. After 30 seconds, if no other buttons are pushed, the control will go back to “Sleep” mode and both buttons will again have to be pressed to see the water temperature set- ting.

2.Release both of the temperature adjustment buttons.

3.The current water temperature setting will be indicated. See Table 4 for an explanation of the temperature indi- cators.

a.To decrease the temperature press and release the “COOLER” button once. The temperature indicators will now display the new temperature setting. Press and release the “COOLER” button until you have reached the desired setting.

b.To increase the temperature press and release the “HOTTER” button once. The temperature indicators will now display the new temperature setting. Press and release the “HOTTER” button until you have reached the desired setting.

Note: Holding down the button will not continue to lower the setting. The button must be pressed and released for each temperature change desired.

Note: To avoid scald injury, set the control to the lowest set- ting that will supply the hot water for your needs. Refer to Table 4 to determine the approximate temperature setting, and the approximate time for scald injury at that tempera- ture.

4.When you have completed setting the control wait 30 seconds for the temperature indicators go off and the control to enter “Sleep” mode.
