  George AndersonAug 7, 2025
  Excessive flare-ups and uneven heat on your Napoleon Gas grill can be due to several reasons. First, check that the sear plates are installed correctly, with the holes towards the front and the slots on the bottom. Refer to the assembly instructions for guidance. Second, preheat the grill with both main burners on high for 10 to 15 minutes. Finally, regularly clean the sear plates and drip pan to remove grease and ash buildup. Do not line the pan with aluminum foil; instead, refer to the cleaning instructions.

Why is the heat low on my Napoleon Gas grill, even when the valve is on high?

  The low heat or low flame on your Napoleon Gas grill, even when the valve is turned to high, can be due to a few reasons. For propane grills, ensure you are following the correct lighting procedure: all gas grill valves must be in the off position when the tank valve is turned on. Turn the tank on slowly to allow pressure to equalize. See the lighting instructions for more details. For natural gas grills, the supply line might be undersized; the pipe must be sized according to the installation code. For both types of grills, improper preheating can be a factor. Preheat the grill with both main burners on high for 10 to 15 minutes.

What to do if the 'paint' is peeling inside the lid of my Napoleon ultra chef 485?

  If it appears that 'paint' is peeling inside the lid or hood of your Napoleon Gas grill, don't worry, this is not a defect. The finish on the lid and hood is porcelain and will not peel. The peeling is caused by hardened grease, which dries into paint-like shards that flake off. Regular cleaning will prevent this. See the cleaning instructions for proper maintenance.

  If the burners on your Napoleon Gas grill are burning with a yellow flame and there's a smell of gas, it could be due to a spider web or other debris in the burner, or an improper air shutter adjustment. Thoroughly clean the burner by removing it, following the general maintenance instructions. Also, a qualified gas installer should slightly open the air shutter according to the combustion air adjustment instructions.

What to do if the infrared burner on my Napoleon ultra chef 485 flashes back?

  Donald SilvaAug 25, 2025
  If the infrared burner on your Napoleon Gas grill flashes back (makes a loud 'whoosh' sound, followed by a blow-torch sound, and grows dim), turn the burner off and allow it to cool for at least two minutes. Relight the burner and burn on high for at least five minutes, or until the ceramic tiles are evenly glowing red. Ensure that no more than 75% of the grill surface is covered by objects or accessories. If the issue persists, turn the burner off, let it cool for two minutes, and relight it. After it cools inspect the burner very closely for cracks. If any cracks are found, contact your authorized Napoleon dealer to order a replacement burner assembly.
