 release the MIN and adjuster buttons
 close the hot tap
 clear the error code (refer to “Clearing Error Code” on page 33)
 recommence the procedure from Step 10 (20 litre model) or Step 8 (27 litre model).
20 litre model – If the adjuster button is released before Step 15, clear any error code (if displayed) and

clear the error in order to complete the installation. To clear an error code:
20 litre model – Turn off the controller by pressing the on / off button.
switch off the electrical supply at the power outlet to the water heater
check the gas isolation valve at the gas inlet to the water heater is fully open
wait five (5) minutes

20 litre model – Turn on the controller by pressing the on / off button.
Maximum test point gas pressure
Refer to the rating label on the water heater for the maximum test point gas pressure.
20 litre model – Follow Steps 10 to 16 of the “Minimum test point gas pressure – 20 litre models” procedure
on page 30, but open the hot tap fully and use the MAX button instead of the MIN button.
27 litre model – Follow Steps 8 to 14 of the “Minimum test point gas pressure – 27 litre models” procedure on
page 32, but open the hot tap fully and use the MAX button instead of the MIN button.
It may be necessary to open two or three hot taps fully, depending upon the model of water heater and the
incoming cold water temperature.
Note: In Step 11 (20 litre model) or Step 9 (27 model), “3H” will be shown on the LED display.
After setting the minimum and maximum test point gas pressures:
Close the hot tap.
Remove the manometer and refit and tighten the test point screw and washer.
Open a hot tap again so the burners ignite.
