1. Turn OFF the gas supply. 2. Turn OFF the 120 V power supply. 3. Remove the front panel from the appliance. 4. Check the gas type using the data plate on the side of the unit. If using a spare PC board, check that the gas type switches are in the correct position (dip switch 1 of SW2: ON for natural gas, NG, and OFF for propane, LPG). See dip switch settings section below. (ON is towards the right and OFF is towards the left.) 5. Attach the pressure gauge to the burner test point, located on the gas control (Fig. 2). 6. Turn ON the gas supply. 7. Turn ON the 120 V power supply. 8. If a controller is installed, turn the unit ON with the controller. Select the maximum delivery temperature and open all available hot water taps at full. 9. Set the unit to “Forced Low” combustion by setting No. 7 dip switch of the SW1 set to ON (Fig. 3). 10. Check the burner test point pressure. 11. Remove the rubber access plug and adjust the regulator screw on the modulating valve (Fig. 4) as required in Table 1. Replace the rubber access plug. 12. Set the unit to “Forced High” combustion by setting both No. 7 and No. 8 dip switches of the SW1 set to ON (Fig. 5). Ensure maximum water flow. 13. Check the burner test point pressure. 14. Adjust the high pressure potentiometer (POT) on the PC board as required to the pressure shown in Table 1. 15. Return the unit to normal operation by setting dip switches 7 and 8 of the SW1 set back to OFF (Fig. 6). Close all water taps. 16. Turn OFF the gas supply and 120 V power supply. 17. Remove the pressure gauge and install sealing screw. 18. Turn ON the gas supply and 120 V power supply. 19. Operate the unit and check for gas leaks at the test point. 20. Install the front panel.
