H.Operating Instructions.

1.Follow Operating Instructions to place boiler in operation. See Figure 36.

2.Electronic Ignition Modules with LED indicators. Table 10 cross-references the ignition module terminal designations to the ignition terminal

numbers in the wiring ladder diagrams. The yellow LED indicates the status of the flame, see Table 11. The green LED indicates the status of the system, see Table 12. See Figure 37 for LED locations. See Figure 38 for Troubleshooting Guide.

aFlash Code Descriptions

-Heartbeat: Constant ½ second bright, ½ second dim cycles.

-The flash code number signifies that the LED flashes X times at 2Hz, remains off for two seconds, and then repeats sequence.
