Page 12: Adjustment Before Firing
ADJUSTMENTS BEFORE FIRST FIRING LOW GAS PRESSURE SWITCH HIGH GAS PRESSURE SWITCH AIR PRESSURE SWITCH Adjustment of the combustion head has been illustrated on page 7. In addition, the following adjustments must also be made: - Open manual valves up-stream from the gas train. - Adjust the low gas pressure switch to the start of the scale (A). - Page 13 AIR PRESSURE SWITCH (A) AIR PRESSURE SWITCH Adjust the air pressure switch after having performed all other burner adjustments with the air pressure switch set to the start of the scale (A). With the burner operating at min. output, increase adjust- ment pressure by slowly turning the relative dial clock- wise until the burner locks out.

Page 14: Maintenance
MAINTENANCE FLAME INSPECTION WINDOW Combustion The optimum calibration of the burner requires an analy- sis of the flue gases. Significant differences with respect to the previous measurements indicate the points where more care should be exercised during maintenance. Gas leaks Make sure that there are no gas leaks on the pipework between the gas meter and the burner. -
