SETTING THE GAS PRESSUREPressures for ‘Burner High Flame’ and ‘Burner LowFlame’ are factory set, however if pressures need to bechecked or adjusted follow the procedures describedbelow. To check outlet pressure at burner ‘High Flame’and ‘Low Flame’ positions remove the plastic cap fromthe regulator adjustment location as indicatedin FIG 29.2. The pressure point is closed with a captive screw. Turnscrew 6 revolutions anticlockwise to open the pressurepoint as indicated on FIG 30 (a) and place manometertube over the test point as per FIG 30 (b).3. Switch the control buttons to ‘High Flame’ position.Wait for heater to switch to ‘BOOST’ setting (time delayon start up). Retain screwdriver in position and usinga spanner adjust the outer nut on the control to givea high pressure reading (refer to specification table onpage 8 & 9). (Turn clockwise to increase pressureand anticlockwise to decrease pressure). ReferFIG 31.4. Switch the control buttons to ‘Low Flame’ position.Retain spanner in position and using a screwdriveradjust the central screw control to give a low pressurereading (refer to specification table on page 8 & 9).(Turn clockwise to increase pressure and anti-clockwise to decrease pressure). Refer FIG 32.5. Remove spanner and screwdriver. Switch from BOOSTto LOW to ensure settings are correct.6. Switch heater off and remove the manometer tube.Tighten pressure test point by turning the captivescrew fully clockwise.7. Replace plastic cap. Ensure the little lug is positionedtowards lower right hand side to clear the controls.8. Refit the fascia, making sure not to damage the powercord or switch cable.9. Operate the heater on BOOST, NORMAL and LOWsettings. The flame should be stable, no lifting from theburner and the logs should glow after approximately15 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 isagainst 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 referto the troubleshooting chart on page 20, or contactSampford IXL in your state.FIG 29FIG 30(a) (b)FIG 28(Burner ‘Low Flame’)Plastic CapPressure adjustment(Burner ‘High Flame’)Pressure testpoint withcaptive screwAdjustHoldFIG 32HoldAdjust1.
