Gas: When you prepare to light the pilot, you are instructed to turn the gas control knob to the pilot position and depress the gas control knob (Reset button

on Robertshaw Gas Valves). When depressed gas will flow to the pilot burner only. You then have to (manually)

ignite this pilot gas using the piezo igniter button. When the pilot is lit, the flame must heat the thermocouple until it generates sufficient voltage to the gas valve to allow you to release the knob while gas continues to flow to the pilot. When the gas control knob is turned to the “ON” position, gas is also available to the main burner if the thermostat calls for heat.

Water Flow: When a hot water faucet is opened, water pressure from the well tank or street main forces cold water into the water heater through the dip tube. This pushes hot water out of the tank.
