OPD EQUIPPED CYLINDER HOSE & REGULATOR
OVERFILL PREVENTION DEVICE
1. The standard for outdoor gas appliances, ANSI Z21.58/
CAN/CGA-1.6, requires that appliances be used with
cylinders equipped with an Overfill Prevention Device (OPD).
2. The OPD is designed to reduce the potential for the overfilling
ofpropanecylinders,thusreducingthepossibility of relief valve
discharges of raw propane. The OPD causes a slower
purge/fill operation. Some consumers have been advised
by filling stations that these cylinders are “defective.” This is
not a defect. Some propane filling stations may not be aware
of this device and its effect on the purge/fill operation.
3. New OPDs coming onto the market have technology that
allows for much greater BTU outputs which will decrease the
amount of time it takes to purge a cylinder.
IDENTIFICATION
To identify these cylinders, the OPD handwheel has been
standardized to the shape shown.
1.
All models are equipped with a hose and regulator with a
QCC®-1 Quick Closing Coupling.
2.
The QCC® coupling contains a magnetic Flow Limiting Device
which will limit the flow of gas should there be a leak between
the regulator and the appliance valve. This device will activate if
the cylinder valve is opened while the appliance valves are open.
Be sure the appliance valves are off before the cylinder valve
is opened to
prevent accidental activation.
3.
The QCC® coupling incorporates a heat sensitive hand wheel
that will cause the back-flow check module in the QCC® cylinder
valve to close when exposed to temperatures between 240°
and 300°F. Should this occur, do not attempt to reconnect the hand
wheel. Remove hose/regulator assembly and replace with a new
one.
4.
The pressure regulator is set at 11 inches WC (water column)
and is for use with LP gas only. The hose and hose couplings
comply with CGA Standard CAN 1.83. No modifications or
substitutions should be attempted.
5.
Protect the hose from dripping grease and keep
the fuel supply
hose away from any heated surface(s), including the base
casting of the barbecue.
6.
Inspect the seal in the QCC® cylinder valve when replacing the
LP gas cylinder or once per year whichever is more frequent.
Replace the seal if there is any indication of cracks, creases, or
abrasion.
7.
Inspect and clean the hose before each use. If the hose is
cracked, cut, abraded or damaged in any way, the hose must be
replaced prior to the appliance being put into operation.
8.
For repair or replacement of the hose/regulator assembly
(see page "component list"),
contact your appliance dealer.
9.
CONNECTION
1.
Be sure cylinder valve and appliance valves are “OFF.”
2.
Center the nipple in the cylinder valve and hold in place. Using
other hand, turn the hand wheel clockwise until there is a
positive stop. Do not use tools. Hand tighten
only. When
making the connection, hold the regulator in a parallel with
the cylinder valve, so as not to cross thread the connection.
3.
Leak test connections. See “Leak Testing.” (page 5)
4.
Refer to lighting instructions. To avoid activating the Flow
Limiting Device when lighting, open cylinder valve slowly
with the appliance valves off. If the Flow Limiting Device is
accidentally activated, turn off cylinder valve and appliance
valves, wait 10 seconds to allow the device to reset, open
cylinder valve slowly, then open the appliance valve.
DISCONNECTION Always close LP cylinder valve and
remove coupling nut before moving cylinder from specified
operation position.
