CHANGING MAIN BURNER ORIFICE
1. Remove the glass door. Follow GLASS DOOR REMOVAL instructions within this manual.
2. Locate & slide the Primary Air Sleeve fully toward the left. This will allow the sleeve to
disconnect from the burner tube. Follow ADJUSTING PRIMARY AIR instructions within this
manual for reassembly.
3. Remove the logs. See LOG PLACEMENT for instructions.
4. Unscrew the two mounting screws that are located at the back rear of the pan burner.
5. Carefully remove the pan burner by sliding it to the right and lifting it out.
6. Use a ⅝” wrench to hold the orifice holder fitting. Use a ½” (13 mm) wrench to remove the
orifice cap.
7. Change the orifice cap to the fuel type desired. Use a small quantity of gas thread seal
compound. Do not overtighten.
8. Reverse steps 1 to 6.
WARNING: When replacing the pan burner using the two screws, you must NOT over-
tighten the screws. Leave the screws “FINGER-TIGHT” allowing the pan burner to
“float”. This is required for expansion & contraction of the pan burner.
