Burners operate dependably in an
inert atmosphere. Burners have machined ends, permitting
assembly of various confi gurations without gaskets.
Stainless steel fl ame retention strips, which give the burner
its stability in high velocity air streams, are fastened so they
prevent combustion between the strip and casting, resulting
in lower strip and casting temperatures to prolong burner life.
Pictured from front to rear are a 4630-P Pilot Section, 4630-T Tee with 3" bottom
inlet, and 4630-B 12" straight with 3" bottom inlet, all displaying various types of
ignition and fl ame detection.

reGen Burner assemblies can be used with inspirators, but aspi-
rator mixers are preferred for good turndown and air/fuel ratio
Burners can be operated at mixture pressures from 0.35 to
12"w.c., giving 6:1 turndown.
4630 Burner sections are shipped unassembled. No gaskets
are used. Be sure to order all appropriate accessories, including
fl anges, endplates, separator plates, and hardware kits
When they get hot, line burner assemblies expand unevenly and
tend to bow in the center. Short assemblies can be bolted down
securely, and fl anges will take up the expansion.
For longer lengths with no bottom feed connections (or one
bottom feed only at the center), support assembly rigidly at its
center, leaving ends free to bow away. When two or more bot-
tom feed connections are used in an assembly, install 4-3159-1
Expansion Ignition Couplings between the bottom inlets.
To order specify:
4630-(appropriate letter)-(capacity rating‡) section description, and 4630HK hardware kits to connect sections.

Situations dangerous to personnel and property may exist with the operation and maintenance of any combustion equipment. The presence of fuels, oxidants, hot and cold combustion products, hot
surfaces, electrical power in control and ignition circuits, etc., are inherent with any combustion application. Components in combustion systems may exceed 160°F (71°C) surface temperatures and present hot
surface contact hazard. Fives North American Combustion, Inc. suggests the use of combustion systems that are in compliance with all Safety Codes, Standards, Regulations and Directives; and care in operation.
