Page 8: Combustion Head Adjustment
COMBUSTION HEAD ADJUSTMENT Installation operations are now at the stage where the blast tube and sleeve are secured to the boiler as shown in fig. (B). It is now a very simple matter to set up the combustion head, as this depends solely on the MAX output developed by the burner. -
Page 9: Gas Piping
GAS PIPING • The main gas train must be connected to the gas attachment 1)(A), using flange 2), gasket 3) and screws 4) supplied with the burner. • The gas train can enter the burner from the right or left side, depending on which is the most convenient, see fig. -

Page 13: Air Pressure Switch
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. -
