Setting the water temperature
The desired temperature of the hot water can be adjusted on the front control panel of the heater.
The 2400 EO 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.
