Use  cleaning  cloths  to  wipe  residue  from threads on all fuel hoses and adapters to be reinstalled. WARNING Pipe  sealant  can  cause  eye  damage or   skin   irritation.      Wash   after   skin contact.  Wear safety goggles/glasses when using.  Avoid contact with eyes or   skin.      If   sealant   contacts   eyes, flush eyes with water and get immediate medical attention. CAUTION Do  not  apply  pipe  sealant  to  leading threads   of   adapters   and   elbows   in screed   burner   system.      Seepage   of pipe   sealant   into   fuel   system   may clog fuel nozzle. NOTE Adapter pipe thread fittings are coded P    in    illustration.        P-coded    fittings require   pipe   sealant.      Adapter   hose end  fittings  are  coded  H,  and  require hydraulic fitting sealant. b. Apply  pipe  sealant  to  P-coded  threads  of adapters and elbows. WARNING Hydraulic   fitting   sealant   can   cause eye  damage  or  skin  irritation.    Wash after     skin     contact.          Wear     safety goggles/glasses  when  using.    Avoid contact  with  eyes  or  skin.    If  sealant contacts  eyes,  flush  eyes  with  water and get immediate medical attention. CAUTION Do not apply hydraulic  fitting  sealant to   leading   threads   of   adapters   and elbows.    Seepage  of  hydraulic  fitting sealant into fuel system may clog fuel nozzle. c. Apply   hydraulic   fitting   sealant   to   H-coded threads of straight adapters and elbows. d. Install straight adapters and elbows. Position elbows (1, 4, 6, and 7) as shown in the   illustration.      Tighten   all    elbows    and straight adapters. WARNING Fuel     is     very     flammable     and     can explode    easily.        To    avoid    serious injury or death: Always   wear   safety   glasses/goggles at all times. Keep  fuel  away  from  open  flame  or any spark (ignition source). Keep  at  least  a  B-C  fire  extinguisher within easy reach when working with fuel or on a fuel system. Do   not   work   on   fuel   system   when screed   burner   is   hot;   fuel   can   be ignited by a hot burner chamber. Post  signs  that  read  "NO  SMOKING WITHIN  50  FEET"  when  working  on screed burner fuel system. e. Route fuel hoses as shown and connect  to adapter   fittings   using   the   illustration   and legend as a guide. f. Install tie wraps as needed. GO TO NEXT PAGE 14-24
