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. Remove NG orifice from elbow fitting. Apply a light amount of
propane/LP resistant sealant to short threaded end of LP orifice (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. Retighten screw.
Note:
Do not replace pan burner assembly in firebox at this time.
Convert the tube burner and pilot assembly first (see Tube Burner
