Operating The Temperature Control System - Kenmore 153.552400 Use And Care Manual

Operating the Temperature Control System

Water Temperature Adjustment
The water temperature setting can be adjusted from 55°F
to 155°F. Turn the Gas Control/Temperature Knob to the
desired setting/temperature. See Figure 22 on page 21.
NOTE: The temperatures indicated are approximates. The
actual temperature of the heated water may vary.
Operating Modes and Settings
The gas control valve has two different operating modes:
Standard and Vacation.
Standard mode allows you to adjust the water temperature to
your desired setting.
Vacation (VAC) mode sets the thermostat at approximately
55°F and is recommended when not using hot water for
an extended period of time. The VAC setting also reduces
energy losses and keeps the tank from freezing during cold
weather, but it can cause a Hydrogen gas build up in the water
system. See "Air in Hot Water Faucets," page 30.
NOTE: The actual temperature of the water in most
installations will be greater than 55°F due to the surrounding
environment and the pilot flame.
