Operation instructions

Setting the water temperature

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

The GWH-635-ES 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.
