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, disabled or elderly persons.
The input of heat into the tank is controlled by an immersion thermostat. These
automatic controls are set at the factory to maintain a water temperature of 120°F.
Note: 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.
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 persons are at the highest risk of being scalded.
• See instruction manual before setting temperature at the water heater.
• Feel water before bathing or showering.
