The thermal conductivity $\\kappa(\\omega)$ of this model has $\\Re\\kappa(\\omega)=\\tilde\\kappa \\delta(\\omega)$, i.e. it is infinite for zero frequency $\\omega$. The weight $\\tilde\\kappa$ of the delta peak is calculated exactly by a lattice path integral formulation. Numerical results for wide ranges of temperature and anisotropy are presented.
