(a) Burner Aeration
The aeration is self adjusting. There is no
facility or requirement for you to adjust
aeration.
(b) Main Gas Pressure Regulator
Adjustment
The main burner pressure must be
set at installation and should not need
readjustment. If adjustment is necessary,
proceed as follows: (The pressure is
best checked by connecting a water
manometer or equivalent to the test
point nipple on the gas control. The test
point pressure must comply with the
value on the Data Plate).
EUROSIT Gas Control:
i. Loosen the plastic cover from the
top of the gas control and ensure
pressure adjustment screw on left
hand side is accessible.
ii. Remove test point screw from upper
nipple on the right hand side of the
gas control and attach manometer.
iii. Light the burner. Rotate adjustment
screw clockwise to increase
pressure, or anti-clockwise to
decrease pressure.
iv. Once pressure is set, rotate
thermostat adjustment knob on
gas control to pilot setting (see
“Operating Instructions”). Remove
manometer and replace the test
point screw.
v. Replace the plastic cover.
vi. Ensure pilot is still lit (if not, relight
as per the “Operating Instructions”).
Rotate thermostat adjustment knob
to desired setting.
Note: Pressure adjustments at gas
cylinder regulator should be conducted
as required to ensure correct supply
pressure to water heater as per
AS5601/AG601.
(c) Ignition System (Spark Gap)
Check that the gap between the spark
electrode and the pilot burner is 3 –
5mm and adjust as necessary. Push
the igniter button to test for a spark.
(WARNING: Only test the spark gap
where there is no build up of gas).
(d) Pilot Flame
Check that the pilot ame plays on
the last 4mm of the Thermocouple. If
necessary, the direction of the ame can
be corrected by careful manipulation of
the pilot burner hood.
