9MAINTENANCE INSTRUCTIONSIt is recommended that this gas grill be thoroughly inspected and serviced annually by a qualified serviceperson.Turn off the gas at the source and disconnect unit before servicing. Maintenance should only be donewhen the grill is cool, to avoid the possibility of burns. A leak test must be performed annually, and when-ever any component of the gas train is replaced.ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due tohigh temperatures and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots onthe castings. To refinish the castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove anyresidue, and paint with high temperature barbecue paint. Protect surrounding areas from over-spray. Follow curingdirections found on the can.PROTECTION OF INFRARED BURNERS - The infrared burners of your grill are designed to provide a longservice life. However, there are steps you must take to prevent cracking of their ceramic surfaces, which will causethe burners to malfunction. Following are the common causes of cracks and the steps you must take to avoid them.Damage caused by failure to follow these 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 remov-ing cooking grates and accessories into or from the grill. If these objects were to fall on the ceramic, it is likely tocrack.2. Water or Other Liquids - Cold liquid contacting a hot surface in substantial amounts can cause the surface tobreak. Do not throw water into the grill to douse a flame. Also if the ceramic or interior of a burner becomes wetwhile not in use, later operation of the burner can create steam, which may produce enough pressure to crack theceramic. In addition, repeated soaking of the ceramic will cause it to swell and expand. This expansion will causeundue pressure on the ceramic and therefore 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 ceramicfor evidence of possible watersoaking. If ceramic appears to be wet,remove the burner from the grill. Turn upside down to drain the excess water. Bring indoors and allow to dry thor-oughly.3. Impaired Ventilation of Hot Air From the Grill - In order for the burners to function properly, hot air must have away to escape the grill. If the hot air is not allowed to escape, the burners may become deprived of oxygen, causingthem to back flash. If this occurs repeatedly, the ceramic may crack. Do not cover more than 75% of the cookingsurface with solid metal (ie. griddle or large pan).DRIP PAN - Slide the drip pan out for easy cleaning. It should be cleaned frequently (every use) to avoid greasebuildup. Grease and excess drippings pass through to the drip pan, located under the gas grill, and accumulate inthe disposable grease tray below the drip pan. Accumulated grease can cause a fire hazard. Do not line the drippan with aluminum foil or sand, as it can prevent the grease from flowing properly. The pan should be scraped outwith a putty knife or scraper, and all the debris should be scraped into the disposable grease tray. This tray shouldbe replaced every two to four weeks, depending on gas grill usage. For supplies, see your Napoleon Gas Grilldealer.CLEANING THE OUTSIDE OF THE GAS GRILL - Do not use abrasive cleaners to clean any painted, porcelainor stainless steel parts. Porcelain enamel components must be handled with additional care. The baked on enamelfinish is glass like, and will chip if struck. Touch-up enamel is available from your Napoleon Gas Grill dealer. Exte-rior grill surfaces should be cleaned while warm to the touch, with warm soapy water. To clean stainless surfaces,use a stainless steel cleaner or a non-abrasive cleaner. Always wipe in the direction of the grain. Do not use steelwool, as it will scratch the finish. Stainless steel parts will discolour when heated, usually to a golden or browncolour. This discolouration is normal and will not affect the performance of the grill.INFRARED BURNERS - Because of the high intensity of the infrared burner, most drippings and food particlesthat fall onto the burner surface are immediately incinerated. However, some debris and residue may remain. Toremove this residue after cooking, turn the grill on high with lid closed for 5-10 minutes.
