TM 5-3895-374-24-2 SECTION OVERVIEW Section  9.2  contains  a  preliminary  checklist,  which  lists  some  things  which  can  cause  problems with the heater and can be easily checked. Section 9.3 lists the special tools required to fully troubleshoot and maintain the heater. Section  9.4  contains  a  copy  of  the  Service  Contact  Report.    This  report  is  completed  by  CEI personnel when a service call is received.  It is included to give you a better idea what questions might be asked if you call CEI for help with a problem. Section 9.5 contains a detailed procedure to assist you in methodically determining the cause of a problem  with  your  heater.    Where  possible,  symptoms  are  included  with  the  problem  to  more easily  identify  the  problem.    For  example,  if  the  problem  is  low  oil  (heat  transfer  fluid)  in  the expansion tank, the symptom would be voltage on #5 on the terminal strip but not on #6.  Also the LOW OIL indicator light would be illuminated. Section 9.6 contains a list of hold and lockout messages which the programmer will display when the heater is shut down due to a problem or safety lockout in a component within the control of the flame safeguard system. Section 9.7 contains a discussion of flame failures. Section  9.8  contains  a  chart  describing  the  symptoms  and  action  to  be  taken  if  one  of  the operational safeguards is preventing normal heater operation. page 3 - 1168
