8.6 — Flame Safety Control
The microprocessor based control requires minimal maintenance because the safety and logic timings are inac-
cessible. There also are not any accessible contacts. Check to see that the retaining screw is securely holding the
chassis to the mounting base. Also check to see that the amplifier and the program module are tightly inserted.
The relay's self-diagnostic ability includes advising when it or its plug-in modules are at fault and require replace-
ment.
