Shut Down Procedure
To view the gas control components described in this procedure refer to the
‘Lighting Instructions’ diagram on page 6.
1. Remove front access panel by following step 2 of ‘Lighting
Instructions’ on page 6.
2. Depress gas knob slightly and rotate gas knob clockwise so that the
red star ‘
’ aligns with the gas knob position indicator on the gas
control body (pilot position). This setting will leave the pilot flame
alight, however the main burner will not be able to ignite.
Note: To reinstate the burner from the red star ‘ ’ (pilot) position,
depress gas knob slightly and rotate anticlockwise to the red line ‘ l’
(ignition) position. Hold in this position for five (5) seconds then
release the gas knob. The gas knob will return to the red flame ‘ ’ (on)
position automatically and the burner will ignite when heating is
required and extinguish when the water in the storage cylinder has
been heated to the set temperature. If the main burner does not light
at the selected setting, the water may already be at the selected
temperature.
3. Replace front access panel or to completely shut down the gas
control, perform steps 4 and 5.
4. Depress gas knob slightly and rotate clockwise to the white dot ‘ ‘
(off) position. This setting shuts the gas control down completely.

(off) position, follow the ‘Lighting Instructions’ on page 6.
5. Replace front access panel.
Note: When switched back on from the red star ‘ ’ (pilot) position or white
dot ‘ ‘ (off) position, the water heater may take up to an hour to reheat.
Temperature Adjustment
Warning: AS 3498 requires that a water heater provides the means to
inhibit the growth of Legionella bacteria in potable water. This water heater
can satisfy this AS 3498 requirement provided it is operating and the
thermostat setting is 60°C or higher.
Thermostat Adjustment – All Models
The thermostat controls the stored water temperature.
The thermostat automatically controls the gas supply to the burner so that a
constant water temperature is maintained within the storage cylinder. The
