With an excess of pellets the igniter tries to light them but can't get enough oxygen to make a flame and just makes smoke which is full of flammable vapor. Then when the flame ignites it sets off the vapor laden smoke which is not really an explosion but a very rapid burn. That's why I always leave the lid open until the flame starts. You can tell by the sound when it does.
