The burner aeration is non-adjustable. The appliance is pre-set to give the
correct heat input on Natural Gas at 20 mbar (8in w.g) inlet pressure and no
further adjustment is necessary. The burner pressure should be checked at
the pressure test point located at the side of the control unit (See figure 9) .
The pressure check should be carried out using a calibrated pressure gauge
after removing the test point screw. The fire should be alight and the left
hand control knob at its fully anticlockwise setting (Maximum flame height).
The pressure setting should be within the limits shown on page 3 of this
manual (Appliance data). After checking the pressure, turn off the fire, remove
the pressure gauge and replace the pressure test sealing screw. Relight the
fire and test all gas joints for soundness using a suitable leak detection
fluid.
