TM 5-3895-374-24-2 8.  MAINTENANCE General Only   qualified   service   technicians   should   make   mechanical   or electrical   adjustments   to   the   burner   and/or   associated   control equipment. Preventative  maintenance  can  usually  be  performed  by  building maintenance personnel. Always  follow  the  information  provided  in  the  “Owner  Operating Instructions” on page 43.  These should be conspicuously posted in the burner room at the time of the initial burner installation and start up. Always turn the power supply off to the burner and close manual fuel valves as appropriate for routine maintenance. Make sure that combustion and ventilation fresh air sources to the burner room remain clean and open. Periodically  check  all  electrical  connections  and  make  sure  the flame  safeguard  control  chassis  is  firmly  connected  to  its  wiring base. Refer to manufacturer's product bulletins supplied with the burner for   maintenance   on   the   flame   safeguard   control   and   other components. Weekly Checklist 1.    Blow  down  the  low  water  cutoff  to  remove  rust  and  dirt.    Be sure  that  the  burner  cuts  off  with  low  water  still  showing  in  the gauge glass. 2.  Check boiler temperature or pressure readings. 3.  Check any burner pressure gauge readings. 4.  Check all burner linkage.  Tighten as required. 5.  Check condition of remote oil pump belts (if used).  Replace as required.  Excessive noise and side wear on the belt indicates the sheaves need realignment. 6.    Visually  observe  the  flame  through  the  heat  exchanger  sight port (if provided) for normal appearance. Monthly Checklist 1.      Lubricate   electric   motors   in   accordance   with   the   motor manufacturer's   instructions.      (Most   burners   have   sealed bearings.) 2.    Check  the  flame  scanner  cell  and  scanner  mounting  pipe  for cleanliness. Yearly Checklist (To be performed by a qualified service technician It  is  suggested  that  the  burner  be  checked  by  a  qualified  service technician twice a year, but on an annual basis at minimum.  The technician   should   use,   but   is   not   limited    to,    the    following procedures. 1.    Remove  oil  drawer  assembly.    Clean  and  check  oil  nozzle, ignition  electrodes  and  air  diffuser  assembly.    Check  blast  tube and fan housing and clean as required. 2.  Check blower motor and blower wheel for cleanliness.  Remove and clean as necessary. 3.  Remove, inspect and clean gas pilot assembly. 4.  Inspect combustion chamber and make repairs as necessary. 5.  Run burner through complete operational sequence and check for correct operation of all interlocks,  operating and limit controls, fuel shutoff valves and other components as appropriate. 6.    Conduct  maintenance  and  service  procedures  as  directed  by the   flame   safeguard   manufacturer's   product   bulletin   that   was shipped with the burner. 7.    Conduct  complete  combustion  analysis  tests  on  burner  and heat   exchanger.      Clean   as   necessary   and   adjust   for   efficient operation at all fuel inputs.
