16.Adjust air shutter on the burner. The air shutter is located on the bottom of the burner on the left. (Fig. 46) Loosen the two nuts holding the shutter in place. On natural gas units, the shutter is shipped fully closed. To convert to LP, reset the shutter as speci- fied in Table 2. (Fig. 34) On propane unit the shutter is set at 1/8” or 3/8” opening depending on rating plate serial number. To convert to natural gas, the shutter should set to fully closed. Refasten the two nuts.

Fig. 35 Remove and replace injector orifices.

NOTE: Be sure burner leg remains at a 90° angle to firebox base after conversion.

17.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° angel to the base. (Fig. 35) This keeps the orifices aligned with the tubes inside burner. Failure to do so could affect the flame appearance and performance of the unit.

18.Place conversion label on valve.

19.Reinstall the right and left log bracket assembly.

20.Replace logs.

21.Replace glass and stove front.

22.Check manifold pressure.

Conversion is complete.
