PAN Burner Orifice Conversion

1.Inside the control compartment under firebox, locate alumi- num tube with flare fitting and adapter fitting on the left side. Loosen flare fitting and disconnect aluminum tube from adapter fitting. Use a 3/4" open end wrench (see Figure 3).

2.Carefully cut away the RTV silicone from the adapter fitting where it passes through the firebox bottom (see Figure 3). Remove adapter fitting from elbow fitting by turning counter- clockwise. Use an 11/16" open end wrench.

3.Inside firebox, locate two small burner hold down brackets on rear of pan burner. Remove screws with phillips screwdriver and carefully lift pan burner assembly up and out of firebox (Do not force the assembly during removal.) See Figure 4.

4.Remove elbow fitting with orifice from burner manifold by turning counterclockwise. Use a 3/4" open end wrench. Re- move NG orifice from elbow fitting. Apply a light amount of propane/LP resistant sealant to short threaded end of LP ori- fice (117, #56) supplied in kit. Thread LP orifice into elbow.

5.Apply light amount of propane/LP resistant sealant to long threaded end of orifice. Thread elbow fitting with orifice into burner manifold and tighten by turning clockwise. Use a 3/4" open end wrench. Make sure elbow fitting faces down.

6.Locate air shutter at end of burner manifold (see Figure 3). Loosen screw and adjust air shutter to fully open position. Re- tighten screw.

Note: Do not replace pan burner assembly in firebox at this time. Convert the tube burner and pilot assembly first (see Tube Burner Orifice Conversion, this page, and Pilot Orifice Conversion, page 4).
