Note: Be sure all pipe threaded connections are tight, and have thread compound to prevent leaks.

1.Remove burner inlet fitting from front burner (installed in burner pan, see Fig- ure 8).

2.Make sure ports on front burner are facing the front (open side) of burner pan. Refit if needed.

3.Using thread sealant (resistant to the action of propane/LP gas) on larger end of fitting, screw the burner inlet fitting through the hole and into the front burner (see Figure 8). Tighten using a 7/8" wrench. If using propane/LP gas, see Propane/LP Gas Conversion, page 10.

4.Apply thread sealant compound to the 3/8" male threads of the burner inlet fitting. Thread the manifold block (see Figure 8) onto the burner inlet fitting. Use the bottom hole of the block.

5.Apply thread sealant to the 1/8" brass pipe nipple and thread it onto the mani- fold block. Tighten with a 7/16" wrench.

6.Slip the air restrictor over the 1/8" pipe nipple. Apply thread sealant to the male threads and install the rear burner nozzle onto the fitting. Tighten with a 9/16" wrench.

7.Place the grate assembly over the burner pan. Install the rear burner bracket onto the grate with the 2 black Phillips head #10 screws provided. Do not tighten at this time (see Figure 9).

8.Install the "U" burner from the left side with the open end in the front (see Fig- ure 9). Hold the rear of the burner higher than the bracket. Slide the burner over the air restrictor fitting. Lower the rear of the burner into the slots on the burner bracket. Install the burner clip and tighten the nuts and screws.

9.Install 3/8 flare x 3/8 male pipe elbow into the inlet of the manifold block. Install the pipe plug into the top of the manifold block. Use thread sealant.
