Hot water when turned on, and the flow sensor detects water and sends a signal to the control panel. The control panel turns the fan on, which draws outside air, and opens up the gas valve. This ignites the burner.

The heat exchanger captures heat from the flames and transfers it to water. This water moves through the exchanger tubings. The mixing valve now tempers the heated water exiting the exchanger.

Also, the temperature sensor helps to detect excess or short water flow. The sealed vent, either on the wall or roof carries exhaust gas. It also sends combustion air to the burner.
