  Michelle PhillipsAug 15, 2025
  Excessive flare-ups and uneven heat in your Napoleon Grill can be caused by several factors: * Sear plates might be installed incorrectly. Ensure they are installed with the holes towards the front and the slots on the bottom. Refer to the assembly instructions. * Improper preheating. Preheat the grill with both main burners on high for 10 to 15 minutes. * Excessive grease and ash build-up on sear plates and in the drip pan. Clean sear plates and the drip pan regularly. Do not line the pan with aluminum foil. Refer to cleaning instructions.

How to fix low heat or low flame on my Napoleon P665NSS when the valve is on high?
- E
  Erin ThompsonAug 18, 2025
  Low heat or flame on your Napoleon Grill when the valve is turned to high can be due to several reasons: * **For Propane:** Improper lighting procedure. Ensure the lighting procedure is followed carefully. 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. Refer to the lighting instructions. * **For Natural Gas:** Undersized supply line. The pipe must be sized according to the installation code. * **For Both Gases:** Improper preheating. Preheat the grill with both main burners on high for 10 to 15 minutes.

What to do if the burner output on my Napoleon P665NSS is too low on the 'high' setting?
- A
  Amanda DicksonAug 22, 2025
  If the burner output on your Napoleon Grill is too low on the 'high' setting, accompanied by a rumbling noise and fluttering blue flame, it could be due to: * Lack of gas. Check the gas level in the propane cylinder. * The supply hose is pinched. Reposition the supply hose as necessary. * Dirty or clogged orifice. Clean the burner orifice. * Spider webs or other material in the venturi tube. Clean out the venturi tube. * Propane regulator in “low flow” state. Ensure the lighting procedure is followed carefully: 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.

What causes the rear and side burners on my Napoleon Grill to not light with the igniter but light with a match?
- S
  Shawn BoydAug 27, 2025
  If the rear and side burners on your Napoleon Grill do not light with the igniter but light with a match, the possible causes are: * Dead battery or battery installed incorrectly. Replace with a premium heavy-duty battery. * Loose electrode wire or switch terminal wires. Check that the electrode wire is firmly pushed onto the terminal on the back of the igniter. Check that the lead wires from the module to the ignition switch (if equipped) are firmly pushed onto their respective terminals. * Lifting flames on the burner. Close the air shutter slightly; see the previous problem description for more details.

Why does it look like the 'paint' is peeling inside the lid of my Napoleon Grill?
- R
  Richard CruzSep 5, 2025
  The 'peeling paint' inside the lid or hood of your Napoleon Grill 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. Refer to the cleaning instructions.
