Safety Instructions
This Navien Combination 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 below before you
decide to adjust the set temperature.
Households with small children, disabled or elderly persons may require
120°F (49°C) or lower temperature setting to prevent contact with “HOT”
water.
Water temperatures over 125°F can cause severe burns instantly or death
from scalds. If the proposed combination water heater outlet temperature is
above 125°F, 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.
Water temperature over 125°F can
cause severe burns instantly or
death from scalds.
Children, disabled and elderly are
at highest risk of being csalded.
