Commissioning

With all gas appliances in operation at maximum gas rate, the inlet pressure at the incoming test point should read 4.5” W.C. - 10.5” W.C. on natural gas and 8” W.C. - 13.5 W.C. on propane gas. If the pressure is lower, the gas supply is inadequate and the unit will not operate to specification. Check the gas meter regulator and pipework for correct operation/sizing as required.

Ensure gas pressure check under Commissioning has been completed first. The regulator is electronically controlled and

factory pre-set. Under normal circumstances it does not require adjustment during installation. Make adjustments only if the unit is not operating correctly and all other possible causes for incorrect operation have been eliminated.

1. Turn OFF the gas supply.

2. Turn OFF the 120 V power supply.

3. Remove the front panel from the appliance.

4. Turn ON the 120 V power supply.

5. Check the gas type using the data plate on the side of the unit. Enter programming mode. Press and hold PB2 until the LED display shows 1. After 2 seconds the display changes to the current gas type. (A = LPG, C = NG)

6. Exit programming mode. Press & hold PB2 until the LED display goes blank.

7. Removing sealing screw and attach the pressure gauge to the burner test point, located on the gas control (shown to the right).

8. Turn ON the gas supply.

9. If a controller is installed, turn the unit ON with the controller. Select the maximum delivery temperature.

10. If no controller, press and hold PB2 until the LED display shows 1, after 2 seconds, it will change to A or c. Press PB3 until the LED display shows 3. Press PB4 until the LED display shows b for maximum temperature setting. Press and hold PB2 to exit programming mode. LED display will turn off and settings will be saved.

11. Open all available hot water taps.

12. Push and hold PB5 to set the unit to "Forced Low." The LED display will show L, the front status monitor will show FL.

13. If adjustments are required, press PB3 to increase pressure, or PB4 to decrease the pressure.

14. Push and hold PB5 to change to "Forced High." The LED display will show H, the front status monitor will show FH.

15. If adjustments are required, press PB3 to increase pressure, or PB4 to decrease the pressure.

16. Return the unit to normal operation: press and hold PB5 until the LED Display turns off.

17. Turn OFF the gas supply and 120 V power supply.

18. Remove the pressure gauge and reinstall sealing screw.

19. Turn ON the gas supply and 120 V power supply.

20. Operate the unit and check for gas leaks at the test point.

Electrical Diagnostics

NOTE: Wiring diagram is available on the inside front cover. Important Safety Notes

There are a number of (live) tests required when performing electrical diagnostics on this product. Proceed with caution at all times to avoid contact with energized components inside the water heater. Only trained and qualified service technicians should attempt to repair this product. Before checking for resistance readings, disconnect the power source to the unit and isolate the item from the circuit (unplug it).

Freeze Protection

This unit has freeze protection heaters mounted at different points to protect the water heater from freezing. All of them should display a positive resistance reading.

Flame Rod

Place one lead of your meter to the flame rod and the other to ground. With the unit running you should read 5 VDC. Set your meter to the

micro (μ) amp scale and arrange meter leads in line with the flame rod. You should read 1 μ amp or greater for proper

flame circuit. In the event of low flame circuit, remove the flame rod and check for carbon or damage.

Amp Fuses

This unit has 1 inline (5) amp glass fuse located on the PC Board. Remove the fuses and check continuity through it. If you have continuity through each fuse then it is functioning. Otherwise the fuse is blown and must be replaced.

Thermistors

Check all thermistors by inserting meter leads into each end of the thermistor plug. Set your meter to the 20 K scale and read resistance. Applying heat to the thermistor bulb should decrease the resistance. Applying ice to the thermistor bulb should increase the resistance. Below are examples of typical temperatures and resistance readings.

• Measure resistance of safety circuit.

• Ensure high fire and low fire manifold pressure is correct.

• Check for improper conversion of product.

Over Temperature Warning

• Check for restrictions in air flow around unit and vent terminal.

• Check for low water flow in a circulating system causing short-

cycling.

• Check for foreign materials in combustion chamber and/or

exhaust piping.

•

Check for clogged heat exchanger.

Electrical Grounding

•

Check all components for electrical short.
