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 of propane cylinders, thus reducing the
possibility 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 hand wheel 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 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
do not allow the
hose to touch any hot surface
, including the base casting
of the stove.
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 the hose before each use. If the hose is cracked, cut,
abraded or damaged in any way, the appliance must not be
operated.
8. For repair or replacement of the hose/regulator assembly,
contact customer service.
CONNECTION
1. Be sure cylinder valve and appliance valves are “OFF.”
2. Align the small end of the hose with the regulator fitting and
turn clockwise until tight.
3. 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
.
4. Leak test connections. See “Leak Testing.” (Page 6)
5. 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.
