Cannon Fitzroy Inbuilt Power Flue | 13setting tHe gas PressUre1. gas valve layout is as indicated in FIG 29.Pressures 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 regulatior adjustment location as indicatedin FIG 30.2. the pressure point is closed with a captive screw. turnscrew 6 revolutions anticlockwise to open the pressurepoint as indicated on FIG 31 (a) and place manometertube over the test point as per FIG 31 (b).3. Switch the control buttons to ‘High flame’ position.Wait for heater to switch to ‘High’ setting (time delayon start up). retain screwdriver in position and usinga spanner adjust the outer nut on the control to give apressure reading of 0.75 kPa for natural gas and 2.65kPa for lPg. (Turn clockwise to increase pressureand anticlockwise to decrease pressure).refer FIG 32.4. Switch the control buttons to ‘low flame’ position.retain spanner in position and using a screwdriveradjust the central screw control to give a pressurereading of 0.4 kPa for natural gas and 1.1 kPa forlPg. (Turn clockwise to increase pressure andanticlockwise to decrease pressure).refer FIG 33.5. remove spanner and screwdriver. Switch from high tolow to ensure settings are correct.6. Switch heater off and remove the manometertube. tighten pressure test point byturning the captive screw 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 HIgH, MeDIuM and lOWsettings. the flame should be stable, no lifting from theburner and the logs should glow after approximately15 minutes of operation on HIgH 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 correctlyIf the heater still does not operate to specification referto the troubleshooting chart on page 19, or contactSampford IXl in your state.fig 30fig 31(a) (b)fig 29burner adjustment(burner ‘low flame’)Plastic CapPressure adjustment(burner ‘Full on’)Pressure testpoint with captivescrewfig 32adjustHoldfig 33Holdadjust
