6. Press the 'UP' button
or 'DOWN'
button to adjust to the required value, If the pressure is already correct
or when the desired pressure is achieved press the 'SET' button
, once to save the setting.
7. The display
, will now show
. If the display does not change to there was an error in pressure setting
and the pressure setting procedure should be repeated from step 1 onward after turning the appliance 'OFF'
8. With the display

Press the heater ON/OFF button
.
9. Setting main burner pressure is now complete. Remove the manometer hose and replace the inlet test point
screw
. Check for leaks using soapy water solution.
Step 7. Checking and setting Pilot burner pressure
1. Remove the pilot burner gas test point screw
, and connect a positive pressure manometer hose.
2. Press the heater ON/OFF button
to start the ignition sequence, the appliance will ignite normally.
3. Press the 'TEST' button
, twice on the PCB control panel, the igniter will spark and the appliance will light
to its lowest setting, (Main burner - stage 1), and the display

6. Check for gas leaks using soapy water, setting or checking pilot burner pressure is now complete.
NOTE
The requirements of AS / NZS 5601 include:
a.
checking whether mechanical extraction ventilation draws air through flue systems or
chimneys or not. If yes, this will most likely result in combustion product spillage from
appliances during their operation.
b.
checking whether the operation of appliances and flue systems or chimneys is
satisfactory.
c.
a method for determining the additional fixed ventilation area required to counteract the
effect of mechanical extract ventilation.
WARNING
Always check gas pressure values with those recorded on this appliance's data plate. Values on
the data plate override values printed in this instruction.
