REPRESENTATIVE ILLUSTRATION

CAUTION

A collision with the grill, as with any metal object, could cause
injury. Use care when moving a portable gas grill.

Moving the grill:

Move the grill slowly. DO NOT run with or pull the grill behind 
you; it could hit you from behind causing injury.

DO NOT move the grill while it is lit or hot, or with objects on 
the cooking surface(s) or side table(s).

After moving the grill:

Check all gas connections for leaks that could occur from the 
movement.

Check the venturi tubes to be sure they are still over
the orifices.

Steps to follow before storing grill:

Clean the grill.

Coat the burner lightly with cooking oil to retard rusting.

For outdoor use only. If the grill is stored indoors, detach and
leave the cylinder outdoors. If left outdoors, turn off the fuel 
supply to the L.P. cylinder and cover the grill for protection from 
the weather. Grill covers may be purchased from a grill dealer 
or manufacturer.

WARNING

If the grill is not in use, the gas MUST be turned off at the fuel
supply cylinder.

Place the dust cap on the cylinder valve outlet whenever the
cylinder is not is 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.

Moving and Storage

Troubleshooting

Problem: Grill will not light when the igniter
button is pushed or has incomplete burner
flame.

Possible Causes and Solutions:

1. Lack of fuel. Check to see that the cylinder valve is open and the

cylinder has fuel.

2. Make sure one of the burners is turned on. Allow up to four

seconds for gas flow to ignite.

3. Make sure the AA battery is fresh.
4. If burner lights with match but not igniter, check the ceramic

electrode position near the burner, the condition of the igniter wire
and its connections. Perform igniter test and replace any
damaged parts.

5. Check for spider webs or insect nest in venturi and clean venturi.
6. Misalignment of venturi on orifices. Position venturi over orifices.
7. Burner ports, orifices, valves or hose have blockage. Clean the

components.

8. Crimped fuel supply hose needs straightened.
9. Regulator failure or damaged hose need to be replaced by an

authorized service dealer.

10. Make sure the hose to the cylinder is properly assembled. See the

section titled “Connecting Type 1 L.P. Gas Cylinders”.

Problem: Yellow flame.

Possible Causes and Solutions:

1. Check for spider webs or insect nest in the venturi and clean

the venturi.

2. New burner may have residual oil which will burn off.
3. Clean off any food residue, grease or seasoning salts on the burner.
4. Air may be in the cylinder if the cylinder was not properly

purged. Use up remaining gas; the yellow flame may
disappear with use.

5. The venturi may be misaligned and needs to be lined up over

the orifice.
