What to do if the Napoleon PTH31GT Patio Heater burner output on high is too low?

If your Napoleon Patio Heater's burner output is too low on the 'high' setting, and you notice a rumbling noise with a fluttering blue flame, here's what to check: * Ensure there is enough gas in the propane cylinder. * Make sure the supply hose isn't pinched, and reposition it if necessary. * Clean the burner orifice and venturi tube to remove any obstructions. * Also, make sure you followed the lighting procedure carefully, with all valves off when you turn on the tank valve, and turn the tank on slowly to equalize pressure. The issue may be caused by the propane regulator being in a 'low flow' state.
