Our model did not have this option. The cabinet below TV looks perfect to install one. Appreciate feedback from those who have done this. Dimplex is brand we're considering.
I cannot help on the installation, but I can say we really enjoy the fireplace in our motor home. It is nice on a cool morning to take the chill off. Good luck on the install.
