System will operate reliably but flame signal
is less than desired.
Note: This indication may flash temporarily
during or shortly after lightoff on some
applications.
Marginal Flame Signal (less than 1.1 µA) -
System may not operate reliably over time.
Service call recommended.
Note: This indication may flash temporarily
during or shortly after lightoff on some
