10ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high temperaturesand weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish thecastings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high temperaturebarbecue paint. Protect surrounding areas from over-spray. Follow curing directions found on the can.PROTECTION OF INFRARED BURNERS - The infrared burners of your grill are designed to provide a long service life. However,there are steps you must take to prevent cracking of their ceramic surfaces, which will cause the burners to malfunction.Following are the common causes of cracks and the steps you must take to avoid them. Damage caused by failure to followthese steps is not covered by your grill warranty.1. Impact with Hard Objects - Never allow hard objects to strike the ceramic. Take care when inserting or removing cookinggrates and accessories into or from the grill. If these objects were to fall on the ceramic, it is likely to crack.2. Water or Other Liquids - Cold liquid contacting a hot surface in substantial amounts can cause the surface to break. Donot throw water into the grill to douse a flame. Also if the ceramic or interior of a burner becomes wet while not in use, lateroperation of the burner can create steam, which may produce enough pressure to crack the ceramic. In addition, repeatedsoaking of the ceramic will cause it to swell and expand. This expansion will cause undue pressure on the ceramic andtherefore it may crack and crumble.i) Never throw water into the grill to control flare-upsii) Do not attempt to operate the infrared burners in open air while raining.iii) If you find standing water in your grill (because of exposure to rainfall, sprinklers etc.), inspect ceramic forevidence of possible watersoaking. If ceramic appears to be wet, remove the burner from the grill. Turn upsidedown to drain the excess water. Bring indoors and allow to dry thoroughly.3. Impaired Ventilation of Hot Air From the Grill - In order for the burners to function properly, hot air must have a way to escapethe grill. If the hot air is not allowed to escape, the burners may become deprived of oxygen, causing them to back flash. If thisoccurs repeatedly, the ceramic may crack. Do not cover more than 75% of the cooking surface with solid metal (ie. griddle orlarge pan).TROUBLESHOOTINGProblem Possible Causes SolutionLow heat / Low flame whenvalve turned to high.For propane - improper lightingprocedure.Ensure lighting procedure is followed carefully. All gas grillvalves must be in the off position when the tank valve isturned on. Turn tank on slowly to allow pressure to equalize.See lighting instructions.For natural gas - undersizedsupply line.Pipe must be sized according to installation code.For both gases - improperpreheating.Pre-heat grill with main burners on high for 10 to 15 minutes.Excessive flare-ups/unevenheat.Sear plates installed incorrectly. Ensure sear plates are installed correctly. The archswithout slots should be located directly above the left andright burners. When the sear plates are installed correctly,six of the eight slots should be in valleys.Improper pre-heating. Pre-heat grill with main burners on high for 10 to 15minutes.Excessive grease and ash buildup on sear plates and in drip pan.Clean sear plates and drip pan regularly. Do not line basewith aluminum foil. Refer to cleaning instructions.Burners burn with yellowflame, accompanied by thesmell of gas.Possible spider web or otherdebris, or improper air shutteradjustment.Thoroughly clean burner by removing. See general mainte-nance instructions. Open air shutter slightly according tocombustion air adjustment instructions.(This must be done by a qualified gas installer.)
