The L.P. gas cylinder has a Type 1 cylinder
valve with a back-check module in its outlet
that will not permit gas to flow until an
evacuation device is installed. To purge the
L.P. gas cylinder, the back-check module must
be opened with an evacuation device.
A. Hose-end valve with a bleed port: 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: L.P.
gas cylinder evacuation can be accomplished
during each purging by using a Type 1
connection. The Type 1 valve outlet has 1-
5/16” external ACME right-hand thread that will
accept this connection.
After purging or filling an L.P. gas
cylinder, do not insert a POL plug into the
valve outlet. Insertion of this 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 in the USA,
refer to: Safety Bulletin NPGA # 133, “Purging
L.P. Gas Cylinders,” and Safety Bulletin NPGA
#130, “Recommended Procedures for Filling
Cylinders.”

CYLINDER VALVES
CAUTION:
When using a cylinder exchange, be sure the
exchanged cylinder is a Type 1 cylinder; a 510
POL cylinder will not fit a Type 1 regulator.
Purge new cylinders before
filling. This tank is easily filled with a standard
CGA 510 POL filling connection.

Take These Instructions to the L.P. Gas Dealer
Do not fill an L.P. gas cylinder
beyond 80% full. If this information is not
followed exactly, a fire causing serious injury
or death may occur.
DANGER:
Purging and filling of L.P. gas
cylinders must be performed by personnel who
have been thoroughly trained in accepted L.P.
gas industry procedures. Failure to follow this
instruction may result in explosion, fire, severe
personal injury or death.
DANGER:
