PART 12 – SHUTDOWN
A. SHUTDOWN PROCEDURE
If the burner is not operating, disconnect the electrical supply.
If the burner is operating, lower the set point value to 70
blower to stop, so all latent combustion gases are purged from the system. This should take a maximum of 40 to 90 seconds.
B. VACATION PROCEDURE
If there is danger of freezing, change the set point to 70
"Shutdown Procedure".
C. FAILURE TO OPERATE
Should the burner fail to light, the control will perform two more ignition trials prior to entering a lockout state. Note that each
subsequent ignition trial will not occur immediately. After a failed ignition trial, the blower must run for approximately 10 seconds to
purge the system. Therefore, a time period of approximately 40 to 90 seconds will expire between each ignition trial.
If the burner lights during any one of these three ignition trails, normal operation will resume. If the burner lights, but goes off in about 4
seconds, check the polarity of the wiring. See electrical connection section.
If the burner does not light after the third ignition trial, the control will enter a lockout state. This lockout state indicates that a problem
exists with the boiler, the controls, or the gas supply. Under such circumstances, a qualified service technician should be contacted
immediately to properly service the boiler and correct the problem. If a technician is not available, depressing and holding the RESET
button for more than 1 second will remove the lockout state so additional trials for ignition can be performed. The unit will try to re-light
once every 6 minutes.
