16.Follow procedure for pilot type 2 to replace pilot orifice.
17.Remove and replace plug on lower right hand side of the valve; Red for LP and Blue for NG. (Page 26, Fig. 49)
18.Remove motor top cap. Depress and turn center plunger until arrow points to correct screw. Red for LP and Blue for NG. NOTE: Plunger will “snap” into NG position when arrow is close to blue screw. It will not “snap” at LP (Red) position. (Fig. 61)
19.Insure manifold pressure remains between 3.2”
-3.5” w.c. for NG and 9,5” - 10” w.c. for LP. To adjust the manifold pressure, for NG, using a torque #10 key turn the blue screw clockwise to increase the manifold pressure. Turn the screw counterclockwise to decrease the pressure. Use the red screw to adjust LP.
20.Replace motor top cap.

21.Replace burner. Slide the burner in at an angle with left side lower than the right side. Slide the left side onto the injectors, making sure the burner leg remains at a 90° angle to the base. Lower the right hand side down in to place. Make sure the burner is as far left as possible and the injector shoulders are inside the burner.
NOTE: It is very critical to keep the left burner leg, which holds the injectors, at a 90° angle to the base. (Fig. 62) This keeps the orifices aligned with the tubes inside burner. Failure to do so could affect the flame appearance and performance of the unit.
22.Place conversion label on valve.
23.Reinstall the right and left log bracket assembly.
24.Reinstall the rear log bracket.
25.Replace logs.
26.Replace glass and stove front. Conversion is complete.
