5. Schematic diagram

The diagram below refers to both the 110 Indoorand 110 Outdoor.

1. When a hot water tap is opened,cold water enters the 110 Indoor or 110 Outdoor.

2. The water flow sensor detects this water flowand sends this information tocomputer.

3. The computer initiates fan motorand sends signal to igniterto create ignition spark.

4. The main, proportional, and solenoid gas valves open to allow gas input.

5. The gas ignitesand flames appear inside the burner chamber.

6. Water circulates through the heat exchanger and is heated up to the settemperature.

7. Using thermistors to measure temperatures, the computer modulates the gas and water valves to

ensureproperoutputwatertemperatures.

8. When the tap is closed, the 110 Indoor or 110 Outdoor shutsdown.
