SPARK TIP
COMMISSIONING
When you have completed the installation, perform a spark test and observe spark rod operation in
the following manner.
1.
Energize the power pack and observe the operation of the ceramic spark gap or spark gap tube.
This is mounted on the PC board, viewed with the power pack door open. A flashing of 180
sparks per minute indicates proper operation.
2.
Observe the spark rod while the rod is still in the guide tube. The spark rod assembly is functioning
properly when discharge of approximately three sparks per second is visible. If the spark rod cannot
be observed in place, mark the rod so it can be repositioned to its previous location. Remove the
rod and place it in a safe location away from any personal contact. Observe the rod for visible
emission of three sparks per second. If the spark rod assembly functions properly, reinsert the rod
into the guide tube at the rod’s original position.
3.
If the rod functions properly, energize the system to observe the rod’s performance with its asso-
ciated fuel gun. Check the following items: igniter fuel pressure, atomizing media pressure, and
combustion air pressure. (Refer to the SureFire Igniter bulletin for pressure specifications.) If the
HESI system functions properly, but the igniter does not light, the HESI rod may need reposition-
ing.
