refractory if previously installed.
29. Reinstall logs by following log placement instructions
located in the appliance installation manual.
19. Turn on fireplace with the green wire disconnected
from the valve. See Figure 3.
20. Use a commercially available, noncorrosive leak check
solution to test for leaks around the pilot. Be sure to
rinse off all leak check solution following testing. See
Figure 5 for leak check points. Extinguish the pilot.
21. Bend pilot shield. See Figure 9 and Figure 10.
22. Install the new pilot shield around the pilot assembly.
Fasten with a screw in the existing left hole. Be sure
