How to fix a Napoleon Prestige 450 when the burner won't light with the igniter?
- A
  Andrew PowellAug 21, 2025
  If your Napoleon Grill burner won't light with the igniter but lights with a match, possible causes include a dead or incorrectly installed battery, a loose electrode wire, the wrong replacement igniter, an improper gap at the electrode tip, or lifting flames on the burner. Replace the battery with a heavy-duty 'AAA' battery, installed with the positive terminal up. Check that the electrode wire is firmly pushed onto the terminal on the back of the igniter. Ensure that one spark systems use a one spark igniter. Ensure the gap between the electrode end and the collector box is between 1/8 - 3/16", adjusting by bending the box. Closing the air shutter slightly might also help.

How to fix low heat or low flame on my Napoleon Prestige 450?
- J
  Joseph DorseyAug 25, 2025
  The low heat or low flame issue on your Napoleon Grill when the valve is turned to high can stem from a few reasons. * For propane grills, ensure you're following the correct lighting procedure, with all gas grill valves off when you turn on the tank valve. Turn the tank on slowly to allow pressure to equalize. Refer to the lighting instructions for the correct procedure. * For natural gas grills, the supply line might be undersized; ensure the pipe is sized according to the installation code. * For both gas types, improper preheating could be the cause. Preheat the grill with both main burners on high for 10 to 15 minutes.

  If your Napoleon Grill burner won't light with the igniter but lights with a match, the problem may be due to a dead or incorrectly installed battery. Replace it with a heavy-duty battery. Also, check that the electrode wire is firmly pushed onto the terminal on the back of the igniter and that the lead wires from the module to the ignition switch (if equipped) are firmly attached. Ensure you're using the correct replacement igniter (one spark systems must use a one spark igniter). Make sure the collector box is tight and the gap between the electrode end and the collector box is between 1/8” - 3/16” (3mm-5mm), adjusting by bending the box if needed. Finally, try closing the air shutter slightly.

Why does my Napoleon Grill have excessive flare-ups and uneven heat?
- R
  Robert BakerAug 29, 2025
  Excessive flare-ups and uneven heat in your Napoleon Grill can occur if the sear plates are installed incorrectly, if the grill isn't preheated properly, or due to excessive grease and ash buildup. Make sure the sear plates are installed with the holes towards the front and the slots on the bottom. Pre-heat the grill with all main burners on high for 10 to 15 minutes. Regularly clean the sear plates and drip pan, and avoid lining the pan with aluminum foil or other materials that can obstruct grease flow.

Why is the heat low on my Napoleon Grill even when the valve is on high?
- M
  Monica CopelandAug 30, 2025
  Low heat or flame on your Napoleon Grill, when the valve is on high, can be due to a few reasons. For propane grills, it could be an improper lighting procedure. For natural gas grills, it may be an undersized supply line. For both, it may be improper preheating. Ensure you follow the lighting procedure carefully, with all gas grill valves in the off position when you turn on the tank valve slowly to equalize pressure. The gas pipe must be sized according to the installation code. Pre-heat the grill with all main burners on high for 10 to 15 minutes.

What to do if "paint" is peeling inside the lid of my Napoleon Grill?
- J
  juan58Sep 1, 2025
  The "paint" peeling inside the lid or hood of your Napoleon Grill is likely hardened grease, not a defect in the porcelain finish. Regular cleaning will prevent this build-up. The grease dries into paint-like shards that flake off.

Why is the burner output on my Napoleon Grill too low?
- K
  Katie WangSep 6, 2025
  If your Napoleon Grill's burner output is too low on the “high” setting, accompanied by a rumbling noise and fluttering blue flame, several factors could be responsible. Begin by checking the gas level in your propane cylinder. Ensure the supply hose isn't pinched and reposition it if necessary. A dirty or clogged orifice could also be the culprit, so clean the burner orifice. Additionally, inspect the venturi tube for spider webs or other material and clean it out. Lastly, for propane grills, make sure the lighting procedure is carefully followed: all gas grill valves must be in the off position when the tank valve is turned on, and the tank should be turned on slowly to allow pressure to equalize. Refer to the lighting instructions.
