screw for each burner). See Figure 18.
3. Remove LP burner orifice marked 55 from each orifice
fitting. See Figure 19.
4. Install natural gas burner orifice marked 49 into each
orifice fitting. Apply pipe compound to threads on ori-
fices prior to installation.
5. Place burners into grill and insert burner tubes over ori-
fice fittings. Secure each burner with one (1) 1/4-20 x
3/4 phillips screw from Step 2.
6. Grasp valve knobs and remove from valves.
7. The low input adjustment screws are located inside
the two valve stems. Use a small screwdriver to turn
each adjustment screw clockwise 1/4 turn (90 degrees).
When valves are in the "OFF" position, the slot in the
adjustment screw should be vertical. See Figure 20.
