Troubleshooting - Napoleon Ultra Chef US405RSB-INFRARED User Manual

ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high temperatures
and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish the
castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high temperature
barbecue 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 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 removing cooking
grates 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. Do
not throw water into the grill to douse a flame. Also if the ceramic or interior of a burner becomes wet while not in use, later
operation of the burner can create steam, which may produce enough pressure to crack the ceramic. In addition, repeated
soaking of the ceramic will cause it to swell and expand. This expansion will cause undue pressure on the ceramic and
therefore it may crack and crumble.
i) Never throw water into the grill to control flare-ups
ii) 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 for
evidence of possible watersoaking. If ceramic appears to be wet, remove the burner from the grill. Turn upside
3. Impaired Ventilation of Hot Air From the Grill - In order for the burners to function properly, hot air must have a way to escape
the grill. If the hot air is not allowed to escape, the burners may become deprived of oxygen, causing them to back flash. If this
occurs repeatedly, the ceramic may crack. Do not cover more than 75% of the cooking surface with solid metal (ie. griddle or
large pan).
Problem
Low heat / Low flame when
valve turned to high.
Excessive flare-ups/uneven
heat.
Burners burn with yellow

TROUBLESHOOTING

Possible Causes
For propane - improper lighting
procedure.
For natural gas - undersized
supply line.
For both gases - improper
preheating.
Sear plates installed incorrectly.
Improper pre-heating.
Excessive grease and ash build
up on sear plates and in drip pan.
Possible spider web or other
debris, or improper air shutter
adjustment.
Solution
Ensure lighting procedure is followed carefully. All gas grill
valves must be in the off position when the tank valve is
turned on. Turn tank on slowly to allow pressure to equalize.
See lighting instructions.
Pipe must be sized according to installation code.
Pre-heat grill with main burners on high for 10 to 15 minutes.
Ensure sear plates are installed correctly. The archs
without slots should be located directly above the left and
right burners. When the sear plates are installed correctly,
six of the eight slots should be in valleys.
Pre-heat grill with main burners on high for 10 to 15
minutes.
Clean sear plates and drip pan regularly. Do not line base
with aluminum foil. Refer to cleaning instructions.
Thoroughly clean burner by removing. See general mainte-
nance instructions. Open air shutter slightly according to
combustion air adjustment instructions.
(This must be done by a qualified gas installer.)
