PROPERTY MAY EXIST IN ANY WATER HEATER IF AN
APPROVED TEMPERATURE-AND-PRESSURE RELIEF
VALVE IS NOT PROPERLY INSTALLED.
For protection against excessive pressures and temperatures
in this water heater, install temperature-and-pressure
protective equipment by local codes, but not less than a
combination temperature-and-pressure relief valve certified
by a nationally recognized testing laboratory that maintains
periodic inspection of production of listed equipment of
materials, as meeting the requirements for Relief Valves and
Automatic Gas Shutoff for HotWater Supply Systems, ANSI
Z21.22-1971. This valve must be marked with maximum set
pressure not to exceed the marked maximum allowable
working pressure of the water heater (150psi). Install the
valve into an opening provided and marked for this purpose
in the water heater, and orient it or provide the tubing so that
any discharge from the valve will exit only within 6 inches
above, or at any distance below the structural floor and
cannot contact any live electrical parts. The discharge
opening must not be blocked or reduced in size under any
circumstances.
CAUTION: A relief valve is designed to discharge
excessively hot water. THE CUSTOMER IS

SERVICE INFORMATION
WATER TEMPERATURE REGULATION
WARNING: Exposure to 125° F or hotter water can
cause scalding injuries. Appropriate caution must be taken
when using hot water. Special supervision must be given to
those who cannot act quickly such as children, invalids 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 120° F. Although these
thermostats are designed to 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. ANY 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 instruction manual before
setting temperature at the water heater.
Feel water before bathing or
showering.
