Top convertible Pilot Hood (version with special spring)
1. The pilot hood is held in place by spring.
First remove the spring, then remove the hood by pulling it up from the pilot bracket (fig. 14).
2. Insert a 5/32" (4 mm) Allen wrench into the hexagonal key-way of the injector (fig. 15), and turn
counter clockwise to remove it from the injector journal.
3. Verify that the new injector is proper for the application. The injector size is stamped on the side
of the injector near the top. LPG injectors have a groove machined around their circumference
near the top, while NG injectors do not have a groove (fig. 17).
Refer to the Appliance Manufacturer's instruction sheet for the proper injector size.
4. Insert the Allen wrench into the end of the injector. Then, install the injector into injector journal,
and rotate the injector clockwise until a recomended torque of 9 lbf in (1.0 Nm) is achieved.
5. First replace the pilot hood by aligning the tab on the base of the hood with the slot in the side
of the pilot journal, and push the hood down, onto the pilot bracket (fig. 16). The hood must sit
squarely on the bracket for proper operation.
Then replace the spring by pushing it on his seat (fig.16).
Check to insure that the hood is properly seated onto the pilot bracket and that the spring is
properly inserted onto his seat.
6. Restore the gas supply to the appliance, and ignite the pilot burner.
Verify proper ignition and operation.
