Page 9: Position Of Electrodes
For operation on flame-reversal boilers, gas pipes must be adjusted RS 400/E BLU to hole position 4, see Fig. (E). RS 300/E BLU ROTATION OF FAN MOTOR Look at the fan motor's cooling fan from the front and make sure it turns anticlockwise. -
Page 10: Gas Line
GAS LINE (A) The gas train is to be connected on the right of the burner, by flange 1) (A). If it is necessary to connect it on the left of the burner, loosen nuts and screws 3) and 4), remove blind flange 2) together with its gasket and fit them to flange 1) tightening the nuts and screws. -
Page 11: Adjustment Before First Firing
ADJUSTMENTS BEFORE FIRST FIRING Adjustment of the combustion head has been illustrated on page 8. In addition, the following adjustments must also be made: - open manual valves up-line from the gas train. - Adjust the minimum gas pressure switch to the start of the scale. -
Page 12: Combustion Air Adjustment
COMBUSTION AIR ADJUSTMENT Fuel/combustion air must be synchronized with the relevant servomotors (air and gas) by stor- ing a setting curve by means of the electronic cam. To reduce pressure loss and to have a wider adjustment range, it is best to set the servomo- tor to the maximum output used, as near to maximum opening (90°) as possible. -
Page 13: Air Pressure Switch
AIR PRESSURE SWITCH (A) AIR PRESSURE SWITCH CO CHECK Adjust the air pressure switch after having per- formed all other burner adjustments with the air pressure switch set to the start of the scale (A). With the burner running at maximum output, measure CO emission in the flue gases, then progressively obstruct the air intake with the aid of the regulating grille (see fig. -
Page 14: Maintenance
MAINTENANCE Combustion The optimum calibration of the burner requires an analysis of the flue gases. Significant differ- ences with respect to the previous measure- ments 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. -
