S8700B,D-F,J-M Direct Spark
Ignition Controls
APPLICATION
S8700 Direct Spark Ignition Controls are designed for
use in a wide range of gas-fired appliance applications
that require direct main burner ignition and flame safety
control of gas burners. The S8700 is used to ignite the
main burner, sense the flame and control the gas valve.
See Table 1 for the model that best meets your
application needs.
The S8700B,E,J,L models provide single rod flame
sensing (i.e., the spark rod also acts as the flame sense
rod). The S8700D,F,K,M models provide dual rod flame
sensing (i.e., the spark rod and flame rod are separate).
The S8700J,K,L,M models provide 30-second minimum
time delay between application of 24V power to the
control and initiation of the trial for ignition period for
applications that require prepurge. All models have an
LED status indicator.
Table 1. S8700 Models.
