Ducane 3400 Hand Assembly, Disconnecting Cylinder, Excess Flow Control, Gas Leak Checks

CONNECTION Liquid Propane Gas Grills

The propane cylinder valve connection provided with this grill incorporates the four important safeguards listed:

Hand Assembly

1.Make sure the cylinder valve and all appliance valves are in their “OFF” positions.

2.When connecting regulator/burner valve assembly to cylinder valve, turn large plastic nut clockwise until it stops.

3.Gas will not flow unless plastic nut is fully engaged.

4.HAND TIGHTEN ONLY.

Disconnecting Cylinder

1.Turn cylinder valve and all appliance valves “OFF”.

2.Turn large plastic nut counterclockwise to disengage coupling.

WARNING: Do not use a tool to tighten the connection. Using a tool could damage the regulator coupling and could cause a leak resulting in serious bodily injury or death, or in a fire or an explosion causing damage to property.

Excess Flow Control

The propane regulator assembly incorporates a flow limiting device designed to supply the grill with sufficient gas flow, yet control any excess flow.

Rapid changes in pressure can trigger the flow limiting device. If the cylinder valve is turned to allow gas flow while a burner valve is open, the surge of pressure will cause the device to activate. The device will remain closed until the pressure is equalized.

This should occur within a 5-second time frame. If the flame remains low, shut off the gas valves, wait five seconds and relight grill one burner at a time.

To ensure that this does not cause difficulty in lighting the grill, follow these instructions:

1.Make sure all burner valves are OFF.

2.Open cylinder valve and wait 5 seconds.

3.Follow lighting instructions.

Temperature-Activated Shut-Off

The large plastic nut on the regulator assembly is designed in coordination with a check valve in the cylinder valve to shut off the flow of gas when exposed to temperatures between 240-300ºF.

In the event of a fire or hose break, one of the safeguards will function to control or stop the flow of gas from the propane cylinder. Never attempt to use damaged equipment.

IMPORTANT

When connecting or replacing any gas pipe with pipe threads or fi ttings, all joints must be sealed with leak-proof sealing compound approved for use with natural and propane gases. After making connections, check all joints for leaks using soapy water and a brush.

Gas Leak Checks

Never use a match or flame for leak detection. Use soapy water or testing solution. Brush the solution onto connection points and look closely for bubbles indicating escaping gas. If leaks are detected, shut off the main gas supply valve and securely retighten connections, then repeat the leak test.

On cabinet models, perform this operation before placing the tank into its storage compartment. After placing the tank in the compartment, recheck the tank to see if any connections were disturbed.

WARNING: Never use an open flame when testing for gas leaks. Use of an open flame may result in serious bodily injury or death, or in a fire or an explosion causing damage to property.

Liquid Propane Tank Safety Tips

•Remember to handle your portable liquid propane tank carefully when you take it to your dealer for a refill. Avoid dropping it or bumping it against sharp objects. Liquid propane tanks are sturdily constructed, but a series of hard jolts could dam- age the container.

•When transporting the tank to your local propane gas dealer, make sure the valve is closed tightly and the protective cover is in place. Prop the tank securely in an upright position so it can’t roll around your vehicle.

•If you plan to make stops for other shopping or errands, have your liquid propane tank filled at the last stop before going home. Again, see that the refilled tank is secure in an upright position, and when you return home, remove the refilled tank from your vehicle. Never leave a portable liquid propane tank inside a vehicle which may become overheated by the sun.

•Your local liquid propane gas dealer will gladly offer you additional safety tips.

Store Liquid Propane Tank Safely

Whether you’re between cross-country treks in your recreational vehicle or looking for a place to keep the liquid propane tank that provides fuel for your outdoor grill, keep in mind some basic safety rules about storing portable liquid propane tanks. Don’t store the tanks - whether full or empty - inside your home, the living area of an R.V., a garage, basement or workshop. It isn’t likely that liquid propane will leak from the tanks, but if it should, the fuel could be exposed to sparks from automobiles, power tools or other appliances. When storing or transporting your LP tank, it must remain in an upright position. Never lie your LP tank down on its side whether it is full or empty. Never store a spare tank near your grill.

CAUTION: Never transport or move your grill or grill tank without first closing the manual valve on your liquid propane gas tank.

CAUTION: Place dust cap on cylinder valve outlet whenever the cylinder is not in use. Only install the type of dust cap on the cylinder valve outlet that is provided with the cylinder valve. Other types of caps or plugs may result in leakage of propane.

The best place to store a liquid propane tank is in a shady or protected spot outdoors, behind your home or garage, but where it is out of reach of children. Liquid propane won’t evaporate, because it’s in a strong, closed container. And it won’t lose any of its clean-burning heat content, even if left outside year-round.

WARNING:When not connected to your grill, any LP gas tank must be stored in an upright position in a cool, shady, ventilated, outdoor location away from your grill or any other heat source. If this information is not followed exactly, a fire causing death or serious injury may occur.

Filling a Propane Tank

It is extremely important that your LP tank be filled properly when you take it to be refilled. Be sure to use a reputable LP dealer and ask him (and watch, if possible) how he fills the tank and knows when to stop. An overfilled LP tank can be dangerous. The proper way to fill a tank is by weight. The empty tank should be placed on a scale and the scale weights readjusted to a weight which would allow up to 80% of the total weight of propane (LP) to be put into the tank. When this weight is reached, the filling operation must be ended. If the tank is not completely empty, the scale readjustment

must be changed to consider the propane (LP) already in the tank.

WARNING: An LP (propane) tank is overfilled if it contains more than 80% by weight of its total capacity of propane (LP). An incorrectly filled or an overfilled LP (propane) tank can be dangerous. If this information is not followed exactly, a fire causing death or serious injury may occur. If a tank is overfilled and the weather causes the warming of the LP tank, (a hot day, tank left in sun or stored indoors) internal pressure is created due to expansion of the propane which in turn causes the LP gas to be released through the pres- sure relief valve on the tank. The pressure relief valve is a safety device required on 20 lb. propane tanks by the Depart- ment of Transportation to prevent a catastrophic tank failure due to excessive pressure. LP gas released from the tank is flammable and can be explosive.
