White Rodgers 37C73U Temperature Regulation, To Turn OFF GAS to Appliance

Page 4

TEMPERATURE REGULATION

After the gas connections are made, water is in the heater and the pilot light is ignited, the control must be set to the desired water temperature.

The recommended water temperature dial setting is at the arrow (). The water temperature out of the heater at this setting will be approximately 120°F.

If you use hot water frequently and in short spurts, water temperature can occasionally exceed the temperature set- ting by up to 30°F because of the dynamics of the appliance.

Figure 3. Water Temperature Dial

The arrow () setting is the safest and most economical. If you want hotter water, rotate the water temperature dial

counterclockwise ( ) to a higher setting. Approximate water temperature delivered at the different settings is shown in the following table.

To avoid scald injury, set the control at the lowest setting which will still deliver your needed hot water.

!WARNING

The hotter the water the greater the risk of scald injury and the shorter the time to cause injury.

Be sure to protect babies and the infirm or others with impaired mobility who cannot get out of the hot water quickly. They are the people most commonly hurt in scald injuries and in need of lower temperature and other protection like supervision, point-of-use temperature control equipment or a system mixing valve. A point-of- use valve or a system mixing valve can be obtained from your plumber.

!WARNING

Never allow small children to use a hot water tap, or to draw their own bath water. Never leave a child or impaired person unattended in a bathtub or shower. Scald burns can result.
