Beckett CG10, CG50, CG25, CG15 instruction manual Gas Gun Installation Replacement Part Numbers

￿￿￿￿￿￿	Use authorized replacement parts
	only. Restrictors are precision-ma-

chined parts and O-rings are rated for fuel contact. Do not attempt to replicate or modify any parts. Refer to Table 1.

The gun assembly is secured inside

￿￿￿￿￿￿ the air tube by a spring-loaded jacking screw. It is spring loaded in order to control the force it can impose on the gun assembly. When installing the jacking screw look inside the air tube to verify that the pointed tip of the jacking screw pin is seated into the small slot on the locating pad on top of the gun. There is also an external verification of correct assembly: when the screw is fully tightened, the e-clip on the top of the center pin should come flush with the top of the screw. Refer to Figure 3.

1.Remove the jacking screw (B) from the housing to free the internal gas tube (C).

2.Gently rock the internal gas tube (C) to loosen the tube from the burner housing (D).

3.Inspect the O-rings and insure that they are prop- erly lubricated. (A silicon O-ring lubricant is recom- mended, but automotive chassis or bearing grease is an acceptable substitute.)

4.Referring to Figure 2, place the restrictor (F) with pre-attached, pre-lubricated O-ring (G) into the internal gas tube (C). Use your hand to press the restrictor into the tube. The O-ring will hold the restrictor in place.

5.Insure that the O-ring (H), attached to the outside diameter of internal gas tube, is properly lubricated and seated against the flange on the internal gas tube.

6.Install the internal gas tube (C) back into the hous- ing, refer to Figure 1. Fit the end of the tube into the external gas manifold (E).

7.Re-install the jacking screw (B). (Refer to the above notice for installation details.)

8.Fill out and place the supplied Conversion Data Plate adjacent to the rating plate.

9.Complete and attach the supplied Adjustment Data

￿￿￿￿￿￿	With the gas restrictor installed, as
	shown in Figures 1 & 2, all burner air

adjustments and gas manifold pressure adjustments for propane will be approximately the same as the natural gas adjustments shown in the burner manual, or printed on the “Mfr’s Settings” label on the burner housing.
