Mass flow control is recommended. Standard 4384 Fuel Directed® Burners have a single gas connection with internal radial/forward gas adjustment for flame shaping. Main and center jet gas should be supplied to the burner at the same time. See flow control schematic. PILOT and FLAME SUPERVISION Burners are ignited with a gas-boosted pilot. Pilot air pressure must be at least 10"w.c., and pilot regulator must be cross- connected to the pilot air line (see Sheet 4014). If flame supervision is used, pilot must be of the interrupted type. UV flame detection is recommended (using an 883_-D adapter). It is possible for a UV scanner mounted on this burner to sight flame(s) of other burners in the same firing chamber. Consult Fives North American Combustion, Inc. for configuration guidiance on multiple burner applications. LOW NOx The 4384 Fuel Directed Burner is an inherently Low NOx burner. In conjunction with other NOx reducing features, it is capable of meeting emission limitations for new or retrofit applications in environmentally sensitive installations. Contact your Fives North American Combustion, Inc. Sales Engineer for specific applications. BURNER TILE CONSTRUCTION 4384 Burners do not include a tile. Tunnel shapes and recom- mended installation is shown on Dimensions & Installation 4384. OTHER FUELS
