What to do if burner output on my Napoleon PRO500-3 is too low?

If the burner output on your Napoleon Grill's “high” setting is too low, accompanied by a rumbling noise and fluted ring blue flame, it could be due to a lack of gas, a pinched supply hose, a dirty or clogged orifice, spider webs or other matter in the venturi tube, or the propane regulator being in a “low flow” state. Check the gas level in the propane cylinder and reposition the supply hose if necessary. Clean the burner orifice and venturi tube. 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 turn the tank on slowly to allow pressure to equalize.
