TM 5-3895-374-24-2 A   Flame-Safeguard   Programmer,   available   in   various control    sequences,    programs    the    firing    cycle.        The operating cycle is sequenced to ensure normal and safe conditions    before    fuel    can    be    introduced    into    the combustion area. The complete firing cycle is supervised   to   ensure   that   ignition   of   main   flame   is properly  established  and  maintained.    Both  direct  spark and   gas   pilot   ignition   systems   are   available.      Flame monitoring  is  provided  by  optical  scanner  of  the  cesium oxide, lead sulfide.  cadmium sulfide or ultraviolet types. The  limit  circuit  includes  the  operating  limit  control   to maintain  set  operating  pressure  or  temperature,  as  well as    a    high    limit    control    to    guard    against    excessive pressure  or  temperature.    Low  water  and  other  similar safety controls can be interlocked into the burner control system to fit specific job and/or code requirements. The control circuit is normally 120 volts.  A control circuit transformer  may  be  furnished  to  provide  the  120   volt control   circuit   for   polyphase   motor   applications.      The control circuit is frequently interlocked with the polyphase motor circuit to shut down  the  burner  in  the  event  of  an interruption of the motor current. Power Flame Type C burners are capable of firing single or multi-fuel applications.  (See model selection, page 6.) For  multi-fuel  burners,  fuel  changeover  may  be  provided  by automatic    control,    influenced    by    outside    temperature    or manual switching.  Interlocking relays and timers ensure safe changeover of fuels by means of a timed interruption of firing, long enough to cause a complete recycle of the programmer. The   prewired   Control   Panel   is   mounted   and   wired   as   an integral part of the burner in accordance with recommendations   of   Underwriters   Laboratories,   Inc.      and National Electrical Code.  Components are wired to numbered terminal  strips.    Panels  and  burners  are  factory  fire  tested before  shipment.    Comprehensive  wiring  and  gas  and/or  oil piping diagrams are furnished with each burner in accordance with individual job or application requirements.  Wall mounted or free-standing control panels are also available. Power Flame C burners are available with control systems to comply   with   the   requirements   of   Factory   Mutual,   Industrial Risk Insurers and any special state, municipal, local and utility company   codes,   including   New   York   City   Department   of Buildings (MEA), NYC Bureau of Air Resources, Commonwealth  of  Massachusetts,  State  of  Connecticut  Fire Marshall, Illinois School Code and others. MODEL IDENTIFICATION The   numerical   suffix   after   the   letter   "C"   denotes   the burner  frame  size.    The  letter  "R"  inserted  immediately after the letter "C" denotes an inverted blower configuration. The  alphabetical  designation  immediately  following  the frame  size  indicates  the  fuels  to  be  used:    "G"  is  gas only; "O", oil only:  and "GO", combination gas/oil. The two numbers following the fuel designation, in all gas and  gas/oil  listings,  denote  the  standard  gas  train  size. (Selected  components  may  be  different  pipe  sizes  than the nominal train size coded.) 10 1" gas train 20 2" gas train 12 1¼  gas train 25 2½  gas train 15 1½" gas train 30 3" gas train Frame size (see capacity ratings) Any alphabetical suffix (such as "A", "B", "S" or "V", etc.) to the fuel   designation   denotes   special   product   coding   (consult factory). See page 6 "Standard Burner Ratings and Component Data" for further information. UNPACKING AND HANDLING Type  C  Power  Flame  burners  are  usually  shipped  as  a unit with an integrally mounted, prewired control panel.  A remote  fuel  oil  pumpset  is  shipped  separately  on  the larger  size  oil  and  oil/gas  units.    Gas  train  components may be mounted on the burner or shipped loose for field mounting. Uncrate burner carefully and check all parts received against the computer generated Burner Specification Sheets supplied by  Power  Flame.    Components  not  mounted  on  the  burner (shipped  loose)  are  designated  with  an  "L"  on  the  sheets. Claims of shortage or damage must be immediately filed with the carrier. WARRANTY AND SPARE PARTS INFORMATION Power Flame offers a 15 month Limited Warranty on all components  from  the  date  of  shipment.    See  inside  of back cover for details. The   Owners   Information   envelope   packed   with   the burner   contains   a   Warranty   Registration   Card.      The Warranty Registration Card is also a request form for a computer   generated   Spare   Parts   List.      An   on-hand supply of spare parts is highly recommended in case of emergency shutdown.  The pre-addressed, postage paid Warranty  Registration  Card  should  be  completed  and returned  to  Power  Flame.    In  the  event  that  the  Warranty Registration   Card   is   lost,   please   contact   Power   Flame's Customer   Service   Department   in   Parsons,   Kansas.      All communications    with    the    factory    will    be    handled    more efficiently if the burner is identified by the burner model, serial and  invoice  numbers.    This  information  is  stamped  into  the burner nameplate that is attached to the integral control panel (or to the burner, when remote control panels are supplied).
