What You Should know About your LP Dual Tank Assembly:
The Type I pigtail consists of a green nylon swivel nut attached to a hose by means of a brass nipple. The ny-
lon nut is designed for easy-grip and features a right-handed 1-15/16" ACME thread. The ACME thread al-
lows a smooth, convenient connection that does not require tools.
The nut swivels on a thermally sensitive sleeve that is engineered to yield when it reaches temperatures be-
tween 240°F and 300°F. This yielding allows a back-check in the cylinder valve to close, shutting off the flow
of gas from the cylinder.
The Type I pigtail also contains a flow-limiting feature specifically designed for the RV application. If there is
catastrophic damage to the regulator of the LP gas system, the device senses the higher rate of gas flow and
shuts down to a flow rate of 10 SCFH or less. However, it is not designed to detect all leaks, or totally shut off
the system in the event of a leak or failure of the system. Under certain conditions, such as when a cylinder
valve is opened, this flow control device will activate, causing a restriction in the supply of fuel to appliances.
The flow control mechanism will automatically reset within a few seconds (once the pressure has equalized in
the system), provided there are no leaks in the system and all appliances have been turned off.
To remedy a low or restricted flow condition, the following procedures should be followed each time the cyl-
inder is opened or restricted flow is evident (for example low flame or yellow flame at burner)
1. Turn main power switch on the smoker to off.
2. Open the LP gas cylinder valve slowly. DO NOT SNAP OPEN.
3. Be sure all connections have been tested with a soapy solution (non-ammonia dish washing liquid) or leak
detector solution CAUTION: Never use a match or other flame to check for leaks.
4. Wait at least 15 seconds before turning the smoker back on.
5. If operational difficulties continue, have the system inspected by a qualified LP technician.
The changeover regulator offers the convenience of changeover from empty to full gas cylinders.
Make sure there is propane in both cylinders before you start. Rotate the knob on the top front side of the regu-
lator until the indicator arrow points toward the cylinder you want to use first. This will be the "service" cylin-
der and the other will be the "reserve" cylinder. Slowly open BOTH cylinder valves. The indicator on the top
of the regulator will turn bright green. The indicator color will stay green as long as there is fuel coming from
the service cylinder. When the service cylinder empties, the regulator will start drawing from the reserve cylin-
der providing an uninterrupted fuel flow to the system. When it switches over, the indicator color changes
from green to red. This red color signals that the service cylinder is empty and needs to be filled. To remove
the empty cylinder, rotate the knob halfway between the two cylinders, the indicator will turn green and the
reserve cylinder becomes the service cylinder. Next, shut off the cylinder valve on the empty cylinder. Turn
the knob the rest of the way to the reserve cylinder, the reserve cylinder is now the service cylinder. Now dis-
connect the empty cylinder and have it refilled. After refilling, reconnect the pigtail and slowly open the cylin-
der valve. The full cylinder now becomes the reserve cylinder. Check that all connections are tight and there is
no gas leak, use a soap and water solution as described in the instructions of how to check for a gas leak in this
manual.
