Setting the water temperature
The desired temperature of the hot water can be adjusted on
the front control panel of the heater.
The water heater has an electronically controlled gas valve that
modulates the burner input in response to both varying hot
water flow rates and/or changes in any incoming and outgoing
water temperatures.
Note: The water heater, running at minimum BTU, may still
achieve temperatures above the desired set temperature. Low
flowing fixtures are the leading cause of this type of
temperature overshoot. To combat this symptom, clean
fixtures or replace with higher flowing ones if necessary.
