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 OPER-
ATE 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.
Proper maintenance is important for any product. It is suggested that the
purchaser follow the preventive maintenance program outlined below.
