Burner and Orifice

■ Proper location of the burner with respect to the orifice is
important. To verify the proper installation of the venturi
tube, use a screwdriver to remove the grill top. The venturi
tube must be located over the orifice fitting. See Fig. 26
(grill top not shown).

Fixing A Fuel Leak

If you detect a leak:
1. Stop a leak by tightening the loose joint, or by replacing
the faulty part with a replacement part recommended
by Coleman. DO NOT attempt to repair the cylinder if it
should become damaged; the cylinder MUST be replaced.
2. If you are unable to stop a leak, remove the cylinder from
the grill. DO NOT use the grill until the leak is corrected.
When to test for leaks:
1. Perform a leak test each time the gas supply cylinder is
connected to the regulator. Leak test anytime a part of the
gas system is replaced.

Start-Up Check List

Failure to follow these safety steps before using the grill
each time could result in a fire that could be hazardous to
you, your appliance or property. It is especially important to
observe these steps after the grill has been stored, moved
or cleaned.
1. Regularly check the burner venturi tubes for blockage
from an insect nest. Read "Cleaning the Venturi" in the
section titled "Care, Maintenance, and Cleaning" , and also
the section titled "Troubleshooting" .
2. Check that all the burner venturi [A] are set over the valve
outlets [B] correctly. The valve orifice [C] must be inside
the venturi. (Fig. 28)
3. Use only the gas specified.
4. Keep the grill on a level surface.
5. Keep the grease pan empty at start up.
