Purging and Evacuating Devices for L.P. Gas Cylinders with Type 1 Cylinder Valves

CAUTION

After purging or filling an L.P. Gas cylinder, DO NOT insert a POL plug into the valve outlet. Insertion of the plug will prevent the back-check from closing. Use ONLY the provided cap and strap attached to the outlet. Close the cylinder valve knob before returning the cylinder to the customer.

For proper purging procedures refer to:

In the US: Safety Bulletin NPGA# 133, “Purging L.P. Gas Cylinders”, and Safety Bulletin NPGA #130, “Recommended Procedures for Filling Cylinders”.

A. Hose end valve with a bleed port (Fig. 17):

Purging can be accomplished using a hose end valve containing a bleed port which also allows for evacuation without the use of an adapter.

B. Hose end valve without a bleed port:

When a hose end valve does not have a bleed port, a separate device must be used for evacuation.

C. Purging using a Type 1 connection (Fig. 18):

L.P. Gas cylinder evacuation can be accomplished during each purging by using a Type 1 connection. The Type 1 valve outlet has an external 1 5/16" ACME right-hand thread which will accept this connection.

TYPE 1

WARNING

This procedure MUST be performed OUTDOORS only! Be sure the L.P. cylinder valve is closed. Attach to the grill. Read and follow the directions on the cylinder and fuel hose safety tags.

CAUTION

In the connection process, the grill side of the connection will seal on the back-check in the valve, resulting in a slight resistance. The connection requires about one-half to three-quarters additional turn to complete the connection. To disconnect, turn counterclockwise. Tighten by hand only. DO NOT use tools.

1.Check that the cylinder valve is closed by turning the cylinder knob clockwise to a full stop.

2.Check that all the grill burner knobs are in the off position.

3.Remove the protective caps from the cylinder valve and coupling nut. NOTE: The coupling nut connects to the large outside threads on the valve outlet.

4.Hold the regulator in one hand and insert the nipple into the valve outlet. Be sure the nipple is centered in the valve outlet. Hand-tighten the coupling nut, taking care not to cross-thread the connection (see Fig. 19).

5.Turn the coupling nut clockwise, tighten to a full stop.

If you cannot complete the final connection, disconnect the regulator and repeat steps 4 through 6. If you are still unable to complete the connection, DO NOT use this valve and regulator!

6.Check that the hose has no kinks or sharp bends and clears areas that will become hot during use. Never put strain on the hose where it joins a fitting.

7.BEFORE lighting grill, check all connections for leaks using the procedure as shown in the section titled “LEAK TESTING”.
