Setting the water temperature

The GWH 1600 H has a gas control that modulates
burner input in response to flow. Its purpose is to
ensure that the hot water temperature will remain
steady, although the water flow demand might vary. The
output temperature can be adjusted with either the
temperature adjustment knob or the gas control knob.
Temperature adjustment knob
The temperature adjustment knob on the front bottom of
the heater (see Fig. 20) adjusts temperature by
adjusting flow capacity. See table 4 for details.
