TEST BOILER The working field has been defined according to EN 676 standard. COMMERCIAL BOILERS The burner-boiler matching is assured if the boiler conforms to EN 303 and the combustion chamber dimensions are similar to those shown in the diagram EN 676. For applications where the boiler does not conform to EN 303, or where the combustion chamber is much smaller than the dimensions given in EN 676, please consult the man- ufacturers.
INSTALLATION 3.1 BOILER FIXING All the installation, maintenance and disassembly operations must be carried out with the electricity supply disconnected. DANGER The installation of the burner must be carried out by qualified personnel, as indicated in this manual and in compliance with the standards and regulations of the laws in force.

5.2 SETTING OF THE AIR DAMPER SERVOMOTOR (see fig. 2) STAND-BY CAM II (Blue) CAM II assures the fully closed position of the air damper, when the burner is shut down (stand by). It is adjusted by the factory at 0°. DO NOT ALTER. FIRST STAGE CAM III (Orange) CAM III adjusts the air damper for the ignition and for the minimum output.
3) Select the manual (MAN) mode operation, and switch ON the burner. 4) When the burner is alight, press the (+) button to manually drive the servomotor to the high fire position and check that the gas pressure also increases. 5) Check the gas flow rate at high fire.
5.5 BURNER START-UP Motor Air damper motor Ignition transformer Valve High fire Low fire D6222 2.5s 3s max. 5.6 MIN. 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.
FAULTS / SOLUTIONS The control box has a self-diagnostic system, by which it is possible to easily check the faults and find the solutions. To use this function, wait for a minimum of 10 sec after the lock out, then push the reset button for 3 sec. After releasing the button, the RED LED will begin to flash, as shown in the following schedule.

3)选择手动 (MAN) 模式运行并且启动燃烧器。 4)当燃烧器着火后,按 (+)按钮手动驱动伺服电机到大火位置,并且检查燃气压力是否随之增加。 5)检查大火时的燃气量。使用阀体上的调整螺钉 V 和 N (主要是 V)设置适当的燃气流量。增加 V 或 N 的设 置,可以增加燃气流量。 6)手动调整风门挡板,使烟气中 CO 的含量达到一定的水平。调整风门挡板的同时也可以通过相应地调整 V 来 改变燃气流量。 7)通过按 (-)按钮把出力降低到小火位置。检查燃气流量,如有必要可以适当调节,只能对螺丝 N 进行调整, 保持烟气中的 CO 含量达标。 8)如果小火位置的出力比要求的偏多或偏少,相应地调整 CAM III(橙色) 。螺丝 N 的任何调整都将影响大火时 的出力。 9)转到大火位置。只通过调整螺钉 V 重新调整大火出力。 10)再次转到小火位置,只通过调整螺钉 V 重新调整小火时的出力。 11)重复第...
