!General Safety Precautions
age, personal injury or fire: DO NOT connect this water heater to a fuel type not in accordance with unit rating plate. Propane gas for propane units. Natural gas for natural gas units. These units are not certified for any other type fuel.
!WARNING
LP appliances should not be installed
To meet commercial water use needs, the thermostat on this water heater is adjustable up to 1600 F (Booster mod- els have a maximum setpoint of 180°F). However, water temperatures over 1250 F can cause severe burns instantly or death from scalds. This is the preferred start- ing point for setting the controls for supplying general purpose hot water.
Safety and energy conservation are factors to be consid- ered when setting the water temperature on the thermo- stat. The most energy efficient operation will result when the temperature setting is the lowest that satisfies the needs consistent with the application.
!D A N G E R
HOT
BURN
Water temperature over 125°F can cause severe burns instantly or death from scalds.
Children, disabled and elderly are at highest risk of being scalded.
See instruction manual before setting temperature at water heater.
Feel water before bathing or showering.
Temperature limiting valves are available, see manual.
Maximum water temperatures occur just after burner has shut off. To find temperature of the water being deliv- ered, turn on a hot water faucet and place a thermome- ter in the hot water stream and read the thermometer.
The following chart details the relationship of water tem- perature and time with regard to scald injury and may be used as a guide in determining the safest water temper- ature for your applications.
TIME / TEMPERATURE RELATIONSHIPS IN SCALDS
Temperature | Time to Produce Serious Burn |
|
|
120˚F | More than 5 minutes |
|
|
125˚F | 1½ to 2 minutes |
|
|
130˚F | About 30 seconds |
|
|
135˚F | About 10 seconds |
|
|
140˚F | Less than 5 seconds |
|
|
145˚F | Less than 3 seconds |
|
|
150˚F | About 1½ seconds |
|
|
155˚F | About 1 second |

The temperature of the water in the heater can be regu- lated by setting the temperature on the electronic ther- mostat. To comply with safety regulations, the thermostat was set at its lowest setting before the water heater was shipped from the factory. See the section titled SET POINT ADJUSTMENT PROCEDURE to set the electron- ic thermostat.
!DANGER
There is a Hot Water SCALD Potential if the thermo- stat is set too high.
NOTE: When this water heater is supplying general pur- pose hot water requirements for use by individuals, a thermostatically controlled mixing valve for reducing point of use water temperatures is recommended to reduce the risk of scald injury. Contact a licensed plumber or the local plumbing authority for further information.
