TEMPERATURE REGULATION
After the gas and electrical connections are made and the
water heater tank is full of water, the control will now start to
heat the water to the factory default setting of approximately
70°F. If a higher setting is desired, start with the setting at the
triangle( ). This is approximately the 120°F setting, and the
safest and most economical setting for the water heater.
To change the temperature setting for either cooler or warmer
water, the following steps are necessary:

These indicators will only remain on for 30 seconds if no
further buttons are pressed. After 30 seconds the control
will go back to “Sleep” mode, and both buttons will again
have to be pressed to see the water temperature setting.
