grates, or cooking surfaces. |
• Be sure to tighten all hardware (screws, nuts, bolts, etc.) |
at least once a year or each grilling season. |
WARNING
After each time the grill is set up or moved, and before lighting the grill, verify that the Valve Orifices are properly located inside the six openings to the Burners. One View Port for each of the six Valve Orifices is located underneath the grill as shown in Fig. 16. Remove the grease trays to reveal the six View Ports.

OF GRILL |
Condition The Grill
•Before using the grill for the first time or after storage,
operate grill 15 minutes on high setting, with lid removed, to burn away oil.
•Once the oil has burned away, check the burner flame per next step.
The Burner Flame
•Keep the cooking surfaces in place.
•Observe the burner’s flame from above, through the grates.
•Flames should appear similar to the good flame shown in Fig. 17 and as follows:
•A good flame should be blue with yellow tip.
•Some yellow tips on flames up to 1" in length are accept- able as long as no carbon or soot deposits appear.
•If flames are excessively yellow and irregular, the oil residue may not be completely burned off, or the venturi may be clogged or may not be properly positioned over the orifices. Allow grill to cool before repositioning venturi over valve and orifices.
•Grills that have been in use for a while sometimes begin to show more yellow flame. A
Clean the burner to remove residue and check for clogged burner holes or blocked venturi (see “Cleaning the Venturi” pg. 12).
•Regular use of your grill will actually help keep it operating more smoothly.
•Each grill may heat differently. Some units will heat some- what more to the center and back of grill. Flavor of grilled food will improve the more you use the grill and as you become familiar with it.

Holes in Burner 
Cleaning the Venturi
WARNING
Spider’s nests or wasp’s mud inside the venturi may cause fire at valve. If a fire occurs, immediately turn off gas supply at L.P. cylinder valve (see representative illustration in Fig. 18).
Note:
Spiders and small insects can spin webs and build nests inside the venturi tubes. This especially occurs in late summer and fall before frost when spiders are most active. These nests can obstruct gas flow and cause a fire in and around the burner valves. Such a fire can cause operator injury and serious damage to the grill. To help prevent a blockage and ensure full heat output, clean and inspect venturi tubes often (once or twice a month). NOTE: Water or air pressure will not normally clear a spider web.
Steps For Cleaning Venturi:
1.Remove the burners from grill.
2.Look inside lower end of venturi tubes for nests, webs or mud.
3.To remove the above obstructions, use an accessory flexible venturi brush or bend a small hook on one end of a
4.Inspect and clean the burner if needed.
5.Replace the burner assembly into the grill.
6.Make sure the valve orifices are inside the venturi tubes.
7.Secure burner back into grill bottom.
