TEMPERATURE CONTROL
A. WATER TEMPERATURE REGULATION
❑ WARNING: Exposure to water hotter than 125° F can cause
scalding injuries. Appropriate caution must be taken when using
hot water. Special supervision must be given to those who
cannot quickly act such as children, disabled, or elderly
persons.
❑ The input of heat into the tank is controlled by a thermostat with a
thermistor (temperature sensor) attached to the water heater. These
automatic controls are set at the factory to maintain a water
temperature of 125° F. Although these thermostats are designed to
meet industry standards, they can fail to control temperature properly
without any notice, and therefore should be tested periodically for
your protection.
❑ The test is very simple: Turn on the hot water faucet and measure the
maximum temperature with an accurate thermometer. If the
temperature is above the safe limits for your circumstances call a
service technician to adjust or replace the control.
❑ DANGER: IF YOU DISCOVER EXTREME HOT WATER COMING
FROM THE FAUCET, IMMEDIATELY SHUT OFF THE MAIN
SWITCH TO THE BOILER AND CALL COMPETENT SERVICE
PERSONNEL. OVERHEATED WATER IS A POTENTIAL HAZARD
TO LIFE AND PROPERTY. DO NOT OPERATE UNTIL THE
SOURCE OF THE PROBLEM HAS BEEN DETERMINED AND
ELIMINATED.
❑ Water temperature over 125° F can cause
severe burns instantly or death from scalds.
❑ Children, disabled and elderly are at the
highest risk of being scalded.
❑ See the instruction manual before setting
temperature at the water heater.
❑ Feel water before bathing or showering.
B. WATER TEMPERATURE CONTROLS
❑ A periodic inspection of the operating controls, heat exchanger and
wiring should be made by qualified service personnel.
❑ The temperature of the water should be tested periodically at the
faucet to be sure the thermostat is working properly.
