SETTING THE GAS PRESSURE
Pressures for ‘Burner High Flame’ and ‘Burner Low
Flame’ are factory set, however if pressures need to be
checked or adjusted, follow the procedures described
below. To check outlet pressure at burner ‘High Flame’
and ‘Low Flame’ positions remove the plastic cap from
the regulator adjustment location as indicated
in FIG 30.
2. The pressure point is closed with a captive screw. Turn
screw 6 revolutions anticlockwise to open the pressure
point as indicated on FIG 31 (a) and place manometer
tube over the test point as per FIG 31 (b).
3. Switch the control buttons to ‘High Flame’ position.
Wait for heater to switch to ‘BOOST’ setting (time
delay on start up). Retain screwdriver in position and
using a spanner adjust the outer nut on the control
to give a high pressure reading (refer to specification
tables on page 8 & 9). (Turn clockwise to increase
pressure and anticlockwise to decrease pressure).
Refer FIG 32.
4. Switch the control buttons to ‘Low Flame’ position.
Retain spanner in position and using a screwdriver
adjust the central screw control to give a pressure low
reading (refer to specification tables on page 8 & 9).
(Turn clockwise to increase pressure and
anticlockwise to decrease pressure).
Refer FIG 33.
5. Remove spanner and screwdriver. Switch from BOOST
to LOW to ensure settings are correct.
6. Switch heater off and remove the manometer
tube. Tighten pressure test point by
turning the captive screw fully clockwise.
7. Replace plastic cap. Ensure the little lug is positioned
towards lower right hand side to clear the controls.
8. Refit the fascia, making sure not to damage the power
cord or switch cable.
9. Operate the heater on BOOST, NORMAL and LOW
settings. The flame should be stable, no lifting from the
burner and the logs should glow after approximately
15 minutes of operation on BOOST setting.
If the flame is unstable:
• Check that the burner is located correctly.
• Check that the glass front is located correctly and is
against the sealing rope.
• Check that the gas pressure is correctly adjusted.
• Check that flue is operating correctly.
If the heater still does not operate to specification refer
to the troubleshooting chart on pages 20 & 21, or contact
Sampford IXL in your state.
