DANGER
HOT
BURN
HOT WATER TEMPERATURE SETTING
●
Water temperatures at or above 125°F (52°C) can cause
severe burns instantly or death from scalds.
●
Households with small children, disabled, or elderly persons
may require 120°F (49°C) or lower temperature setting to
prevent contact with “HOT” water.
●
To prevent scalding, check water temperature after servicing.
●
If the proposed water heater outlet temperature is at or
above 125°F (52°C), a thermostatically controlled mixing
valve or temperature limiting valve should be considered to
reduce the risk of scalding. Contact a licensed plumber or
the local plumbing authority for further information.
●
This Navien Water Heater is factory set at 120°F (49°C) for
your safety and comfort. Increasing the set temperature
increases the risk of accidental scalding. Consult the chart
