OVERFILL PROTECTION DEVICE (OPD) ON
20 LB. PROPANE CYLINDER
Attention: Consumer be advised, this outdoor gas fireplace
must be connected to an LP gas cylinder incorporating an
OPD.
The OPD will help reduce the potential for the overfilling of the
propane cylinder, thus reducing the possibility of hydrostatic
relief valve discharges.
Overfill Protection Device Valve Function
1. As the cylinder is filled, the rising level of liquid propane lifts
the float to the stop position to prevent dangerous overfilling.
Does not affect the filling process or use of the cylinder.
2. At a safe filling level, the float cam triggers the pin to fall into
the recess of the cam, sealing this path off and preventing any
more liquid propane from flowing through the lower valve
body into the cylinder.
3. The propane builds up pressure in the chamber (center spring)
and pushes the piston up to form a seal, effectively stopping
the filling process.
4. The use of the propane from the cylinder allows the OPD to
reset itself for the next fill.
5. Connects to all standard or quick-connect couplings.
6. The Overfill Protection Device affects incoming liquid pro-
pane flow only. Does not affect normal propane gas discharge
when properly connected to the appliance regulator.
7. All propane cylinders should be filled by qualified profession-
als only.
Purging
1. Due to the decreased Btu delivery, purging may take longer.
2. To increase the speed of purging, open the outage valve during
release.
3. Reminder: Each new cylinder must be purged before filling.
4. For purging instructions, refer to NPGA 133-89(a).
Btu Delivery
The OPD valve has a size 56 orifice through which the propane
is released for consumption. Depending on the propane's tem-
perature and pressure, the release from the cylinder is approxi-
mately 125,000 Btu/hour.
IMPORTANT INFORMATION ABOUT YOUR
NEW TYPE-1 OUTDOOR GAS FIREPLACE
CONNECTION
Read all outdoor gas fireplace and related product literature
before connecting or using your outdoor gas fireplace, and read
the following information completely before attempting to con-
nect your outdoor gas fireplace to a propane cylinder.
Keep these instructions in a safe place. You may need to refer to
them when connecting other cylinders after filling.
Your new outdoor gas fireplace regulator is equipped with a
coupling nut. Do not attempt to connect any propane cylinder not
equipped with a mating Type-1 cylinder valve.
Connecting the Regulator to the Valve (Figure 1)
This Type-1 cylinder valve contains a backcheck which is
designed to prevent propane from flowing until the valve is
properly connecting to a regulator.
When connecting the regulator to the Type-1 cylinder valve, be
sure the pressure relief valve is directed away from the front of
the outdoor gas fireplace and away from any building. If the
pressure relief valve should open, the propane will then be
directed where it is likely to do the least harm if ignited.
WARNING: Do not insert any foreign objects into the
valve outlet. You may damage the backcheck. A damaged
backcheck can be the source of a leak. Leaking propane
may result in explosion, fire, personal injury or death.
Regulator Coupling Nut
The coupling nut connects to the large outside threads on the
valve outlet. To complete the connection, follow the steps below.
1. Be sure main burner knob is in the OFF position.
2. Make sure the cylinder valve handwheel is in the closed
position. Turn clockwise (left to right) to a full stop.
3. Remove the protective caps from the cylinder valve and
coupling nut.
4. Turn the coupling nut clockwise (left to right), to tighten to
a full stop. Be sure the coupling nut is not cross-threaded.

Qualified Installing Agency
Installation and replacement of gas piping, gas utilization equip-
ment or accessories and repair and servicing of equipment shall
be performed only by a qualified agency. The term "qualified
agency" means any individual, firm, corporation or company
which whether in person or through a representative is engaged
in and is responsible for (a) the installation or replacement of gas
piping or (b) the connection, installation, repair or servicing of
equipment, who is experienced in such work, familiar with all
precautions required and has complied with all the requirements
of the authority having jurisdiction.
The installation must conform with local codes or, in the absence
of local codes, with either the American National Standard
(National Fuel Gas Code) known as NFPA 54 and ANSI Z223.1
or CAN/CGA-B149.1 NATURAL GAS INSTALLATION CODE
or CAN/CGA-B149.2 PROPANE INSTALLATION CODE.
