You can either melt the chocolate and heavy cream in a double boiler on top of simmering water and mix until creamy or in a microwaveable bowl cooked in 15 second intervals and stirred until melted.
Pour melted chocolate into a warm fondue pot.
Pour the caramel into the center of the chocolate mixture. Do not stir.
Add the rum to the pot and ignite carefully using a lighter.
Allow the flame to burn out and stir gently to combine.
Sprinkle with pecans.
Keep fondue warm over low heat.
