Y8610U INTERMITTENT PILOT RETROFIT KIT
13 68-0291—03
Connect Ignition Cable
Use the provided ignition cable to connect the S8610U module
to the pilot burner.
Be sure the ignition cable is not exposed to high temperature
while the appliance is operating.
NOTE: The cable must not run in continuous contact with a
metal surface or spark voltage may be greatly
reduced. Use ceramic or plastic standoff insulators as
required.
To install:
1. Connect one end of the cable to the male quick connect
SPARK terminal on the ignition module.
2. Connect the other end of the cable to the igniter or
igniter-sensor stud on the pilot burner/igniter-sensor.
Wiring Connections
Connect the provided harness to the ignition module and the
gas control. The harness ends are labeled for easy installation.
See Table 4.
Use Fig. 15 and Table 5 to make the remaining wiring
connections.
NOTE: The 24V terminal on the S8610U is used only when a
vent damper is installed.
Fig. 16 on page 14 illustrates the typical wiring connections in
a heating system with an atmospheric burner.
