NOTE: The RM7888 is a component of a larger overall
combustion safety system for industrial-burner appli-
cations. Due to the custom design nature inherent in
industrial-burner control systems, the system designer/
integrator has responsibility for the overall combustion
system safety and system approval. Separate appli-
ance or site approval may also be required. The
RM7888 serves as a system component that provides
control and flame safety monitoring for an individual
burner.
