TM 5-3895-374-24-1 GP467FB 9. Set the internal FUEL SELECTOR switch to the desired fuel position 10.  Adjust the remaining limit switches to the values required by your application.  Consult the Manufacturer’s literature for the proper method of switch adjustment. 11.  Final adjustment of the low and high pressure switches should be made at the time  of  Initial  startup.    To  adjust  the LOW air pressure switch, reduce the air pressure at the burner until the burner goes out or Improper combustion takes place * The pressure should then be increased by whatever amount is necessary to maintain ignition or the desirable condition.* The LOW fuel pressure switches should also be adjusted to break at a pressure just below that required to maintain burner ignition at the desirable condition.* The HIGH fuel pressure switches should be adjusted to break at a pressure just above that obtained at the burner during correct high fire operation.  Refer to vendor literature for correct method of switch adjustment. *IMPORTANT Fuel flows should not exceed the amount of available air for combustion In normal operation  in  order  to prevent formation of carbon monoxide and/or unburned fuel.  The fuel flows should be limited by setting the high fuel pressure switches to prevent incomplete combustion in normal circumstances If atmosphere is  of  a  reducing  type  (i.e.    ,  CO  or  unburned  fuel  present),  additional  safety  precautions  will  dictate  the proper setting of the high pressure switches. E.  FINAL CHECKOUT 1. Be  sure  that  all  equipment  and  components  have  been  installed  in  accordance  with  the  manufacturer’s  Instructions and drawings. 2. Verify that all necessary preliminary adjustments have been made. 3. Be sure all switches and valves are properly installed and correctly wired 4. Be sure all traps and filters in the system which may have accumulated dirt or other foreign material 5. Make a final check of all fuel and air supply lines for leaks caused by loose fittings, unions, valves, etc. F.  PANEL OPERATION 1. With  the  panel  power  OFF,  open  the  hinged  door  and  verify  that  the  FUEL  SELECTOR  switch  is  In  the  desired position. 2. Open all manual shutoff valves to supply air and fuel to the system. 3. Place the panel POWER switch in the ON position, the following events will occur. a.  The alarm horn will sound.  Press the ALARM SILENCE pushbutton. b.  The burner control motor will drive to Its low fire position. c.  The Tertiary Air Damper, If applicable, will drive OPEN for purge.
