1. | Determine which side the gas line will be coming into the fire- |
| place. |
2. | Using a hammer and screw driver, remove knockout plug from the |
| side of the pan that corresponds to the gas line (see Figure 6). |

Adapter Fitting
3. | Unscrew burner inlet fitting from burner manifold. |
4. | Place burner manifold in pan with threaded opening facing |
| open knockout plug. |
5. | Using thread sealant (resistant to the action of propane/LP gas) |
| on larger end of fitting, screw the burner inlet fitting through |
| hole and into burner manifold (see Figure 6). Tighten using |
| a wrench. |
6. | Using burner clamp, screw, and nut provided, assemble clamp |
| to pan (“U” style and triple burners only). This will hold the |
| burner manifold in place. |
