Just as far as the technical stuff goes, Frank can die if his wood burns. He can obviously be killed by normal means, but I'm not sure if the wood would burn as a result of Frank dying. However the fire created by the wood is the fire of life so it makes sense that if Frank's life is burning out, so would the firewood.
