Warning
Non-Latching All
Flame is detected outside of normal operations by the
flame rod. All burners on the manifold are unavailable.
Modulating manifolds will allow another retry 10-300
seconds after the error condition is created (depends on
the duration of the flame), and the error condition is
cleared. Fixed capacity manifolds will allow another retry
10 minutes after the error condition is created, and the
error condition is cleared.
Possible causes: Gas valve may be stuck open or
malfunctioning. Flame rod may be malfunctioning.

Created due to either the Roll out switch or the Tstat. This
diagnostic is triggered when the cool down timer has
expired, therefore indicates longer term failures, likely
the roll out switch. Verify Primary Limit input. All burners

Manifold 1 or 2 has tried unsuccessfully to start 12 times
in a row with no ignition. The Heat Failed Ignition Delay
Manf X Burner Y diagnostic has occurred 3 times in a row
with no ignition. All burners on the manifold are

will not inhibit manifold 1 from running.
A manual reset is required.

Possible causes: Faulty wiring. Faulty control.
Mod Gas control boards:
The Valve Actuator did not reach a Park or Full On
position. All burners on the manifold are unavailable until
the condition is corrected. Will allow another retry 10-30
seconds after the error condition is created, and the error

Staged Gas Control Boards:
The gas valve state is lo when it must be hi, or hi when
it must be lo. All burners on the manifold are unavailable
until the condition is corrected. Will allow another retry 10
minutes after the error condition is created, and the error
condition is cleared.
