To avoid damage to people and things, it is essentialto observe all the points indicated in this handbook. Thereported indications do not exonerate the Client/Userfrom observing general or specific laws concerning acci-dents and environmental safeguarding. The operator must wear proper DPI clothing (shoes, ) and respect the general safety, preventionand precaution norms. To avoid the risks of burns or high voltage electrocu-tion, the operator must avoid all contact with the burnerand its control devices during the ignition phase andwhile it is running at high temperatures.

2 All ordinary and extraordinary maintenance must beperformed when the system is stopped. To assure correct and safe use of the combustionplant, it is of extreme importance that the contents of thisdocument be brought to the attention of and be meticu-lously observed by all personnel in charge of controllingand working the devices. The functioning of a combustion plant can be dange-rous and cause injuries to persons or damage to equip-ment. Every burner must be provided with certified com-bustion safety and supervision devices. The burner must be installed correctly to prevent anytype of accidental/undesired heat transmission from theflame to the operator or the equipment.

5 NM - E3501 rev. 08 - 22/05 NM series identifies a family of Nozzle Mix gas bur-ners. The combustion air flow, passing through the mixerbody, drags the fuel gas inside the refractory block inwhich complete mixing takes place, thus shape of the refractory block creates a particularvery long stabilized flame .

Max 1750 CF3501I04F3501I03NM - E3501 rev. 08 - 22/05 AND DETECTIONI gnition of the Nm series burners must always be carriedout at low fire by a PBC & PBST series pilot burner (datasheet E3280). After ignition, the pilot burner must beexcluded from the main burner, therefore flame detectionmust take place via a photocell placed anticlockwise fromthe actual pilot burner.

7 For low power models direct ignition is allowed via DSEor WAND series electrodes (data sheet E5805 andE5806). In this case detection must occur via a UV-2 pho-tocell (data sheet E7001). flame control devices are compulsory in all plants opera-ting at temperatures lower than 750 C. (*) In most cases, flame detection with photocell is recommended.

9 08 - 22/05 NM burners are nozzle-mix long flame burners . Theparticular shape of the refractory block ensures a tenseand very stable flame . They are suitable for both ambienttemperature air or preheated air. The modulating controlwith cold air involves the use of a motorized valve on theair side controlled by the signal coming from the tempera-ture controller and a zero-governor on the gas side drivenwith the air pressure signal. The instrument is used formaintaining the ratio between the combustion air and gasthroughout the operating range. In the case of adju-stments with preheated air, the zero-governor is control-led by the pressure coming from a pressure regulatorF3501I05double membrane, which generates a signal that is pro-portional to the variation of air flow.
