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.
