One other thing to keep in mind, If you use an electric starter... you know the ones that look like a mini oven element, only keep it plugged in for 8-10 minutes otherwise it can overheat and explode too.
From the Maverick website...
The instructions above tell you to remove the electric starter from the charcoal after 8 minutes. The reason for this is that your electric starter will attain a temperature of 1000°F. This temperature will hasten the deterioration of your starter and with sufficient wind; the charcoal will melt the sheath of the element. If you leave you starter in the charcoal and if it is still plugged in, there is danger of explosion as the sheath reaches the melting point.
