CHAPTER 7
Troubleshooting
7.1 — Overview
Chapter 7 assumes that the unit has been properly installed and adjusted, and that it has been running for some
time. It is further assumed that the operator has become thoroughly familiar with both burner and manual by this
time. The points under each heading are set down briefly as possible causes, and suggestions or clues to simplify
locating the source of trouble. Methods of correcting the trouble, once it has been identified, may be found else-
where in this manual.
If the burner will not start or operate properly, the troubleshooting chapter should be referred to for assistance in
pinpointing problems that may not be readily apparent.
Troubleshooting should be performed only by personnel who are familiar with the equipment and who have read and
understand the contents of this manual. Failure to follow these instructions could result in serious injury or death.
Disconnect and lock out the main power supply in order to avoid the hazard of electrical shock. Failure to follow these
instructions could result in serious injury or death.
NOTE: The make or model of the program relay provided will vary depending upon job specifications. The following
sequence applies regardless of the make or model. Please refer to the Wiring Diagram (WD) prepared by Cleaver-
Brooks for your specific installation.
