What to do if Napoleon Grill burner output is too low?
- WWayne CummingsAug 14, 2025
If the burner output on your Napoleon grill's 'high' setting seems too low, accompanied by rumbling noises and a fluttering blue flame, several factors could be at play. First, check the gas level in your propane cylinder. Ensure the supply hose isn't pinched. Clean the burner orifice and the venturi tube to remove any obstructions like spider webs. Also, make sure you're following the correct lighting procedure: all gas grill valves should be off when you turn on the tank valve, and the tank should be opened slowly to equalize pressure. Refer to the lighting instructions for further guidance.
