In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
We have a Honeywell flame control on an industrial burner. When we tried to start the burner we get a message "Standby hold: F/G (Flame Detected) The problem is that the burner was cold and there is no flame. What can we check for? how or why would the eye produce a flame signal with no flame? Or is one of the control modules bad?
