OVERVIEW
1. Mount the power pack in a suitable location as far as possible from the burner front extreme
temperatures. Ensure that cable connectors are facing downward.
2. Carefully insert the HESI spark rod tip into the guide tube until the spark rod extends into the
primary ignition zone. With Fireye SureFire 20 gas igniters, position spark tip flush with front of
baffle plate.
3. If retraction assembly is supplied, manually or automatically exercise the retract assembly to
verify correct operation.
4. Once tip penetration is set, attach and tighten the locking device to the spark rod.
5. Connect cable assembly from the power unit to the spark rod. Tighten threaded connection.
6. Connect power input leads to H (hot), N (neutral), and G (ground) to terminal block 2 inside the
power pack.
7. Energize the power pack to test the spark tip. Observe proper operation.
