Sorry, there was obviously some miscommunication involved here.
Without a doubt there are double walls from the blower located at the rear at floor level...up the entire rear of the stove and across the entire top of the stove. It can either exit horizontally out top front opening...or if that opening is blocked and the (11X19) opening is used...then heat exits vertically out that (11X19) opening.
It comes with an opening on the front (3 X 25) and an opening on the top (11X19) to distribute warm clean air into your home.
I'll reserve comment on the sides.
