Alert 354: Abnormal Recycle Delta-T limit

This safety was breached as the inlet and outlet temperature difference exceeded 70°F. This is done to prevent damage to the heat

exchanger. Before this error appears, the combustion air blower would have slowed down in an effort to prevent such an error from

occurring.
